Investigation of the Rate Dependences of the Stress of Plastic Flow and Fracture of Mn2-Si Steel at Normal and Elevated Temperatures
摘要
Abstract
The Hugoniot elastic limit and spall strength of reactor Mn2-Si steel under shock compression were measured by recording and subsequent analysis of the wave profiles. The temperature-rate dependences of the resistance to high- strain rate and fracture of steel at normal and elevated temperatures are determined. The results of measurements of the strength characteristics of steel under spall are supplemented by a metallographic analysis of the fracture zone and compared with data for 15Kh2NMFA reactor steel and Armco iron.
