Effect of Different Heat Treatments on Mechanical Properties of AISI Steels

Abstract

Heat treatment has great importance on the mechanical properties of materials. This paper reports experiments on effects of heat treatment on the mechanical and microstructures behavior of AISI 1040 and AISI 1060 steel. To analyze the effect of different heat treatments, AISI 1040 specimens were prepared through quenching, quenching and tempering, normalizing and spheroidizing. To understand effect of tempering time/temperature and annealing time on AISI 1060 steel specimens were prepared through annealing and tempering. Tensile test and hardness test were performed on steel specimens. The mechanical properties of steel specimens were correlated with the microstructure of steels.
