In the context of forging, this is where a piece of metal is heated before it undergoes intense pressure and heat until it becomes malleable enough to be worked. It*s also where metal is heated in a crucible or mold to melt it down and create a solid shape
The high temperatures that are used to forge metal can cause it to become brittle or crack. That*s why the material needs to be tempered after being forged into shape. This means that it has been heated and cooled several times 〞 which makes it more malleable and less susceptible to cracking when subjected to even more pressure than before.
