i was listening metal and rock since i was 5...i loved it so much...but there is one thing that i just couldn't understand...really quot;what is the difference between death and heavy metal??quot; i am sure that death metal have a lot of screaming in every song,but i just cannot figure that out!.. :P thank again..
a metal is a chemical element whose atoms readily lose electrons to form positive ions (cations), and form metallic bonds between other metal atoms and ionic bonds between nonmetal atoms.[ and Metalworking is the process of working with metals to create individual parts, assemblies, or large scale structures
Metal working is, generically, the permanent deformation of a piece of metal. Can be done many different ways. Hot working is defined as working the metal at the recrystallization temperature (the temperature at which a cold worked structure will be fully recrystallized in 1 hour). As a rule of thumb, the rexstal temp is one half the absolute melting point for pure metals (the homologous temperature). This rule of thumb can be off significantly when you are dealing with alloys, particularly highly alloyed compositions. In these cases, the alloying can increase the recrystallization temperature and, therefore, require higher temperatures to achieve hot working. Hope this helps.
