Investigation of the Effect of Heat Treatment Parameters on Mechanical Properties of AISI 4140 Alloy Steel by Quenching in Water

Yusuf YILMAZ, Ethem KESTI


Abstract: In this study, the changes in the mechanical properties of AISI 4140 alloy steel, which was hardened by quenching in water, and then tempered by different temperatures, as a result of tempering at different temperatures were investigated experimentally. In this study, tensile and impact test specimens were prepared. These specimens were collected in 2 groups. While the first group of these samples was subjected to hardening by quenching only, the samples in the other group were also subjected to tempering processes after quenching. As a result of the heat treatments, these samples were subjected to tensile tests according to TS 138 EN 10002-1/2004 and to impact tests according to TS EN 10045-1/1999. As a result of the experiments, the changes in the mechanical properties of the samples, which were hardened by quenching, were investigated at different tempering temperatures.
