Re: metal that gets stronger when heated
Any metal can get stronger when heated if you're talking about the right temperature range. If the metal is below its ductile-brittle transition point, then heating it will make it more ductile, which will in turn make it tougher. But for most mundane metals, that transition point is very low.Originally Posted by The Last Spartan

probably some metal with a high melting point (if my chemistry is right) like tungsten

Re: metal that gets stronger when heated
Are you thinking of various memory metals like nitinol (or something like that)? When you expose them to heat they snap back into their orignial shape but I don't know about getting stronger.
In "The Core" unobtanium got stronger as it was heated. Hollywood wouldn't show us something that isn't real would they?

Re: metal that gets stronger when heated
I have not heard of a metal that gets stronger when heated. However I do know any metal can be made stronger by heating and cooling it at the proper rates.

doesnt that make cracks, and/or the metal becomes warped ??

no, steel is hardened by heating/cooling. sword smiths used clay to coat parts of the steel they want to cool slowly to control whether or not they want a soft or hard steel. a good sword will have hard steel on the cutting edge and soft steel elsewhere so absorb impacts.
you can also fold steel while it's hot and maleable and cool it to give it sort of a grain/molecular pattern that makes it stronger as well
i imagine this can be done with other metals/alloys as well

Re: metal that gets stronger when heated
Its called heat treating. The hotter you get a metal and the quicker you cool it off, the harder it gets. However hard metal is also brittle, so there is always a balance.
