Effect of Quenching and Tempering and Austempering Treatments on the Microstructural Evolution and Mechanical Properties of High-Strength Bolt Steel
This study systematically compares the effects of quenching and tempering (Q&T) and austempering on the microstructural evolution and mechanical properties of 42CrMo and 40CrNiMo high-strength bolt steels. The steels were subjected to Q&T or austempering after austenitization, and their microstructures, tensile propert...
