Effect of Heat Treatment on Microstructure and Mechanical Properties of Heat-resistant Cast Steel

Liiu Zhao-jing

Abstract

After normalizing and tempering heat treatment for G-X12CrMoWVNbN10-1-1 heat-resistant cast steel, observe the microstructure of the steel on casting, normaling and tempering state respectively; cooled in air and oil after austenitic, research the effect of quenching rate on the microstructure and mechanical properties; tempering in different high temperature after normaling; research the effect of tempering temperature on microstructure and mechanical properties.
