Effects of Heat Treatment on Microstructure of High ...
Today's advanced steels are required to possess high strength and ductility. This can be accomplished by producing appropriate microstructures with a certain volume fraction of retained austenite. The resulting microstructure depends on material's heat treatment and alloying. High ultimate strengths and sufficient elongation levels can be obtained by various methods, including quenching ...

Austenitic Manganese Steel |
Apr 03, 2014· Austenitic Manganese Steel. Increasing manganese and carbon contents led to increasing brittleness up to % manganese. At manganese contents above 10 % however, the steel became remarkably tough. The toughness increased by heating the steel to 1000 deg C followed by water quenching, a treatment that would render carbon steel very brittle.
