摘 要：The tensile properties of alloy steel 35CrMoA were measured by dynamic tension experimental apparatus,and the stress-strain curves of the material at strain rate range from 10-2/s to 103/S were obtained.The fracture appearance and metallurgical structure were observed for the recovered specimens.The influence of strain rates on mechanical properties and microstructure of the 35CrMoA steel was analyzed.Based on the experimental data of mechanical properties,the JC constitutive parameters were fitted for 35CrMoA.
