4340 steel bars were austenitized at 850° C for 1h followed by heating at 700° C for 90min
and quenching into a salt bath at the temperature range of 300–450° C for 1h to obtain dual …

Abstract A steel containing Fe–0.20 C–1.57 Mn–1.55 Si–0.0029 P–0.0018 S (wt%) was
treated by quenching and partitioning (Q&P) and quenching and tempering (Q&T) process …

The alteration of material tensile properties is inevitable after material subjects to irreversible
damage. This paper is devoted to quantify the influence of pre-fatigue damage on the …

In engineering applications, to increase productivity and to decrease production costs, the
selection of the proper engineering material is essential. At that point, machining operations …

The microstructure and wear behavior of a 500 Brinell hardness (HB) grade wear-resistant
steel tempered at different temperatures were investigated in this study. The tempering …

Ultrahigh-strength low alloy 42CrMo4 steels, widely used in the automobile industry, were
heat treated by two different cycles, namely: conventional austempering above the …

Most failures in steel materials are due to fatigue damage, so it is of great significance to
analyze the key features of fatigue strength (FS) in order to improve fatigue performance …
