摘要: Abstract The dynamic tensile test of 0.11C-0. 62Si-1.65Mn TRIP steel was carried out at different strain rates and temperatures. results show that both temperature rate affect the retained austenite transformation. At high rates, uniform elongation decreases, whereas total energy absorption increase. strength is less sensitive. With raising temperature, reduced mechanical properties generally deteriorate, especially 110 °C. However, excellent were obtained 50 °C 75
