Impact toughness of multilayer steel materials at low temperatures

IOP Conference Series: Materials Science and Engineering, 2019
Abstract The results of a number of studies show that there are ways to drastically change the temperature dependence of the impact strength of structural steels, which at first glance have a paradoxical character. It was established that when the test temperature decreases down to cryogenic temperatures, the work of failure of impact ...

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.
