Effects of temperature on the microstructural evolution and mechanical properties of copper − bearing medium manganese steel during tempering

Materials & Design
This work introduced the effects of higher tempering temperatures on the microstructural evolution of Cu − bearing medium Mn steel. After quenching steel at 860 °C for 1 h, it was tempered at 600, 640, and 670 °C for 2 h.
