摘要
利用帽形试样和分离式Hopkinson压杆试验技术 ,研究了船用 90 7A钢在 γ≈ 10 5s- 1的条件下的高应变率行为 ,通过对形成转变带温度场的理论计算和透射电镜分析 ,对该钢绝热剪切带的微结构演化 。
The high strain rate behaviors of 907A steel with the shear strain rate of ≈10 5s -1 have been investigated by Split Hopkinson Bar and hat shaped specimen. The microstructure of evolution of transformed band in this steel has been examined by the theoretical computation of temperature field and the analysis of transmission electron microscopy (TEM). Dynamic recrystallization and phase transformation in adiabatic shear bands has also been discussed.
