Effects of High-Temperature Tempering on Mechanical Properties and Microstructure of SA738 Gr.B Steel

Effects of High-Temperature Tempering on Mechanical Properties and Microstructure of SA738 Gr.B Steel

In this paper, JMatPro thermodynamic software, OM, SEM, TEM, and EPMA were used to study the microstructure and mechanical properties of SA738 Gr.B nuclear power steel after tempering at 630–710 °C. When tempered within the range of 630–670 °C, a huge amount of M<sub>3</sub>C and MC carb...
