    View this video on the Forging process! Open-die forging can produce forgings from a few pounds up to more than 150 tons. Called open-die because the metal is not confined laterally by impression dies during forging, this process progressively works the starting stock into the desired shape, most commonly between flat-faced dies. In practice, open-die forging comprises many process variations, permitting an extremely broad range of shapes and sizes to be produced. In fact, when design criteria dictate optimum structural integrity for a huge metal component, the sheer size capability of open-die forging makes it the clear process choice over non-forging alternatives. At the high end of the size range, open-die forgings are limited only by the size of the starting stock, namely, the largest ...

Structural engineering is a specialized branch of civil engineering that entails analyzing and designing structures -- things like buildings, bridges and even concert stages. Engineering is a big discipline that involves a systematic approach to designing solutions to problems experienced in the real world. There are many different fields of engineering, like mechanical engineering, electrical engineering, civil engineering, chemical engineering and systems engineering. And within these categories there are various subcategories-- and structural engineering is a subcategory of civil engineering. Transcript Ever wonder how tall buildings can withstand windy days, or why bridges don't collapse when large trucks drive over them? The answer is structural engineering. Structural engineers use physics and math to design and analyze the sturdiness of structures, things like bridges, buildings, concert stages, and even roller coasters. Don't get me wrong. Designing any one of these things can involve multiple types of engineering, but it's structural engineering that's responsible for making sure that that structure won't collapse or fall over. You see, a structure must be able to handle the forces or loads that it's likely to experience. Take a skyscraper, for example. It not only has to support itself, but also all the people and furniture inside the building, and then external factors, like wind, snow, or an earthquake. The materials and geometry that make up a structure influence how it may respond to those forces. Different materials have different properties, like strength, weight, and flammability, that can influence a structure's sturdiness. For example, steel is generally stronger, and weighs more than wood, and different geometric shapes work better for different purposes. For example, a square or rectangular base can typically hold more weight than a triangular base. Structural engineers perform calculations to determine the best materials and shapes to use in order to build a study structure. The next time you find yourself at the top of a roller coaster, you can thank structural engineers for doing their part to make sure it's nice and sturdy.

Thinking natural disasters. When you think of natural disasters, there are several that come to mind. You have earthquakes, volcanoes, tornadoes, hurricanes. But, if I show you marshmallows, and I show you toothpicks, and tell you that we’re about to do an experiment that has to do with natural disasters, you’re gonna be, like, “Wait, what? Marshmallows and toothpicks, and natural disasters? But you.” Yeah, we’re going to do that, and I have a challenge for you. This is your challenge: I need you to get a bag of marshmallows, and you know what I love about this, is if your marshmallows ever get stale, the worst thing to do as a scientist is to throw them out. You can reuse anything, rather than making it into garbage. Now, you have a challenge, and your challenge is this, can you create a multi-story structure, a structure, I think, that people can build? So, you have to make it multi-floored, which means more than one or two, I would say. And, here’s the kick, after you build it, it has to be standing. You’re not allowed to hold it up. It has to be free-standing and stable. Stable on the table. Gravity should not be knocking it down. Then, we’re going to simulate an earthquake. So, after you’re done, and you've made this really awesome structure, made out of only marshmallows and toothpicks, we’re going to shake the table, and we’re going to make an earthquake. And you can be, like, “Earthquake.” Just tremble and vibrate. And if your structure is still standing after 30 seconds of your simulated earthquake, you, my dear, are an engineer. And check this out. Your structure’s actually gonna be three-dimensional, and all you need are marshmallows, and all we need are toothpicks. It doesn't matter if they’re the pointy type or the flat type, but, marshmallows are actually cylinder shapes. So, take a marshmallow, take a toothpick, put it through. You kinda have, it looks like you’re going to be working out with it, but you’re not. Now, think about how we can take this, and turn it into a really awesome three-dimensional shape. I’m going to start with this square, and then I’m going to build it up, and turn this square into a cube. Now I’m going to start going higher, just like this. And the beauty about this experiment is, a bag of marshmallows is so inexpensive. Toothpicks, pretty much anybody has toothpicks at home. And, I can learn so many amazing concepts of engineering, building, gravity, center of gravity. You see, you really want this structure to have this amazing centered gravity, so that, If you really think about it, gravity’s always trying to knock you down. In fact, unfortunately, when we get a little older, you start to lean forward, because in your lifetime, your body has done nothing but battle gravity. Which is why our backs arch as we get older. But, now look. I just made a three-dimensional cube. This is exactly one floor high. But the challenge is, could you create multi floors. And, as you get it to go higher and higher, it has to be stable. Stable on the table. You do not want it to be not balanced. The rules are you’re not allowed to hold it up. This is a challenge. And you’re only allowed to use toothpicks; you’re not allowed to get Scotch tape. Okay? That’s the challenge. And, as you can see already, mine is starting to lean. Gravity’s always pulling on it. I’m only gonna make mine three toothpicks high, just because I don’t need to make it bigger. That’s gonna be your challenge. Then, I’m gonna simulate an earthquake, and then, I’m gonna see if my structure is still standing. And, there are other things that you can do, actually, to try to make your structure more stable. Questions like, ‛What happens if you added toothpicks across the squares?’ Something like this. Would this help? Would this help? Science is all about asking questions. Test them, and see what happens. That’s two toothpicks high, and now I’m gonna go three toothpicks high. And by the way, if you don’t have marshmallows, you can actually use gumdrops. My whole point of this is, you can build and learn about structure and engineering and earthquakes, using any materials that you have at home. Uh-oh, gravity. Stop. There we go, it does get a little harder as you get higher. You gotta realize that, and you guys are gonna get frustrated. Starts to look like the leaning Tower of Marshmallows. And, I’m just going to put my toothpicks across the top, and then I’m gonna shake the table, and it’s earthquake time. Will my structure still be standing? Will it fall? I

The most common application is metallurgical. Heat treatments are also used in the manufacture of many other materials, such as glass. Heat treatment involves the use of heating or chilling, normally to extreme temperatures, to achieve a desired result such as hardening or softening of a material. Heat treatment techniques include annealing, case hardening, precipitation strengthening, tempering, normalizing and quenching. It is noteworthy that while the term heat treatment applies only to processes where the heating and cooling are done for the specific purpose of altering properties intentionally, heating and cooling often occur incidentally during other manufacturing processes such as hot forming or welding... Metallic materials consist of a microstructure of small crystals called "grains" or crystallites. The nature of the grains (i.e. grain size and composition) is one of the most effective factors that can determine the overall mechanical behavior of the metal. Heat treatment provides an efficient way to manipulate the properties of the metal by controlling the rate of diffusion and the rate of cooling within the microstructure. Heat treating is often used to alter the mechanical properties of a metallic alloy, manipulating properties such as the hardness, strength, toughness, ductility, and elasticity. There are two mechanisms that may change an alloy's properties during heat treatment: the formation of martensite causes the crystals to deform intrinsically, and the diffusion mechanism causes changes in the homogeneity of the alloy. The crystal structure consists of atoms that are grouped in a very specific arrangement, called a lattice. In most elements, this order will rearrange itself, depending on conditions like temperature and pressure. This rearrangement, called allotropy or polymorphism, may occur several times, at many different temperatures for a particular metal. In alloys, this rearrangement may cause an element that will not normally dissolve into the base metal to suddenly become soluble, while a reversal of the allotropy will make the elements either partially or completely insoluble. When in the soluble state, the process of diffusion causes the atoms of the dissolved element to spread out, attempting to form a homogenous distribution within the crystals of the base metal. If the alloy is cooled to an insoluble state, the atoms of the dissolved constituents (solutes) may migrate out of the solution. This type of diffusion, called precipitation, leads to nucleation, where the migrating atoms group together at the grain-boundaries. This forms a microstructure generally consisting of two or more distinct phases. Steel that has been cooled slowly, for instance, forms a laminated structure composed of alternating layers of ferrite and cementite, becoming soft pearlite. Unlike iron-based alloys, most heat treatable alloys do not experience a ferrite transformation. In these alloys, the nucleation at the grain-boundaries often reinforces the structure of the crystal matrix. These metals harden by precipitation. Typically a slow process, depending on temperature, this is often referred to as "age hardening". Many metals and non-metals exhibit a martensite transformation when cooled quickly(with external media like oil,polymer,water etc.). When a metal is cooled very quickly, the insoluble atoms may not be able to migrate out of the solution in time. This is called a "diffusionless transformation." When the crystal matrix changes to its low temperature arrangement, the atoms of the solute become trapped within the lattice. The trapped atoms prevent the crystal matrix from completely changing into its low temperature allotrope, creating shearing stresses within the lattice. When some alloys are cooled quickly, such as steel, the martensite transformation hardens the metal, while in others, like aluminum, the alloy becomes softer... https://en.wikipedia.org/wiki/Aluminium
