I came across the word while reading about  Heat Treatment of Plain Carbom Steels and the explanation was not easy to understand.

It is Widmanstatten Structure, not Wandermanstateen, and is\na structure characterized by a geometrical pattern resulting from the formation of a new phase along certain crystallographic planes of the parent solid solution. The orientation of the lattice in the new phase is related crystallographically to the orientation of the lattice in the parent phase. The structure was originally observed in meteorites but is readily produced in many other alloys with certain heat treatment.\n\n\nU can go to find some links with the right spelling.\n:)

There is some research in this area.  There apparently are two types of decomposition.  Most references I see list 400-500C, but the research reference gives two temp ranges.

Instead of trying to explain it in text,\nI made a little file as an example.\nTry downloading this file.\nGood luck!

I think you'd better to go to Wikipedia and check for some terms and definitions first.\nYou can find the wiki using simple words in explaining different things.

it's just a summary..dont be afraid. its basically the way you understand the concept.maybe you can throw in your own little example.

I don't believe very many people will answer your question because it's hard to understand what it is you're asking .

Your teacher is crazy and using words that are not correct.  Though I believe that they mean "untwister".  Please tell your teacher to use correct terms.  If you want to impress them, tell them the "untwister" is actually called a topoisomerase.

There are literally thousands of grades of steel out there. Each one having different properties including tensile strength, carbon content, etc.  If you are wanting to know about a certain application, its best to consult an engineer. If you are just wanting to learn a little about it, just get a book about engineering materials.

met·al·lur·gy (mĕt'l-ûr'jē) \nn.\nThe science that deals with procedures used in extracting metals from their ores, purifying and alloying metals, and creating useful objects from metals.\nThe study of metals and their properties in bulk and at the atomic level.\n\nMetals are shaped by processes such as casting, forging, rolling, extrusion, sintering, metalworking, machining and fabrication. With casting, molten metal is poured into a shaped mould. With forging, a red-hot billet is hammered into shape. With rolling, a billet is passed through successively narrower rollers to create a sheet. With extrusion, a hot and malleable metal is forced under pressure through a die, which shapes it before it cools. With sintering, a powdered metal is compressed into a die at high temperature. With machining, lathes, milling machines, planing machines and drills are used to cut the cold metal to shape. With fabrication, sheets of metal are cut with guillotines or gas cutters and bent into shape.\n\n"Cold working" processes, such as rolling and fabrication, where the product’s shape is altered while the product is cold, can increase the strength of the product by a process called work hardening. Work hardening creates microscopic defects in the metal, which resist further changes of shape.\n\nVarious forms of casting exist in industry and academia. These include sand casting, investment casting (also called the “lost wax process”), permanent mold casting and continuous casting.\n\nWelding is a technique for joining certain ferrous metals and certain aluminium alloys. The metals in the weld and on both sides of the join are generally similar alloys. Brazing is a technique for joining copper-based metals.\n\nMetals can be heat-treated by annealing, quenching and case hardening to alter properties of toughness, hardness or resistance to corrosion. Annealing is used to make a shaped product tougher by reducing the effects of work hardening. Quenching and case hardening are used to make a shaped product harder.\n\nElectroplating is the main surface treatment technique and involves bonding a thin layer of another protective metal such as gold, silver, chromium or zinc to the surface of the product to reduce corrosion

to temper something means that you are heat treating it... it is not possible to "temper" something by adding another ingredient.  (temper means heat)\n\n Annealed glass which has been heated to a temperature near its softening point and forced to cool rapidly under carefully controlled conditions is described as "heat-treated glass." The heat treating process produces highly desirable conditions of induced stress (described below) which result in additional strength, resistance to thermal stress, and impact resistance.

mixture of iron and carbon produces steel but there may be some chromium in it.

It's not a bad word, just out-of-date -- like Negro.  I think the history of the mulatto experience (especially in the Americas) and the connotation assigned to the word by some of it's users is what upsets people.  As a 'technical mulatta' I'll tell you...I could give a damn.

Whoa......not quite so simple to explain on here...I was researching it for family reasons and this is a great article I found.

Can you clarify your question? It is very hard to understand.\n\nThanks

Its the word again. They don't know the difference.  Maybe some will look it up\nIllegal or legal--maybe repeat post and they will see the difference. Sometimes it takes that to understand. Than we can work on what raciest is.\n\n\nClueless

Your question is not clear ... you will need to explain more clearly what you need.
