Basics of Quench Process Hardening of Powder Materials and Irons in Liquid Media

In the paper fundamentals of steel parts quench process in liquid media are considered which used for designing new technologies such as intensive quenching that results obtaining fine and nano – bainitic microstructure. These include French law transient nucleate boiling establishing during media, duration, when film is absent, self regulated thermal process. Based on listed fundamentals, versions austemering processes via cold proposed. That allows microstructure hardened materaials. Examples performing austempering provided by author paper. The proposed method combined with martensite transformation may appear supercooled austenite amount less than 50%. Ideas can be engineers scientists dealing materials heat treatment processes.
