Abstract

Abstract: The annealing and annealing-aging processes are employed to control the austenite volume fraction,austenite stability, and VC precipitates in hot-rolled Fe-10.2Mn-0.41C-2.2Al-0.6V medium manganese steel to optimize the mechanical property combination, respectively. The results show that the yield strength, tensile strength and total elongation of the annealed-aged medium manganese steel are obviously improved. A large amount of nano VC particles are the main factor for increasing the yield strength.

Key words: medium manganese steel, aging process, austenite, work hardening
