Modern methods of heat treatment

In the introduction given subject is focused on basic heat treatment (HT) types, on which selected, the most perspective HT ways follow-up, including their analyses and/or physical metallurgical principles. Further, structures stability and instability conditions are discussed, which occur in case of up-to-day types of surface treatment of metal materials, e.g. after electo heating, plasma or laser exposition. Heat treatments of chosen nonferrous metals are integral part of subject. Up-to-day HT technologies enable to reach promising mechanical-metallurgical steels properties under economical advantageous conditions and favourable energy demands.
