Tensile Properties and Deformation Behavior of Beryllium at Different Strain Rate AITranslate
Abstract AITranslate
The strain rate tensile tests of isostatie beryllium were carried out with the universal testing ma- chine at room temperature. The fracture and plastic deformation behavior of beryllium were investigated by using SEM and EBSD techniques. The results show that with the increase of strain rate, the strength of beryllium is increased, but the ductility is decreased and the stress intensity factor of beryllium material is also decreased. In addition, during the stretching process, the slip is the main mechanism of plastic deform- ation. The twin crystals have no obvious effect on plastic deformation for the isotropic effect of mechanical properties of isostatic beryllium,and have little contribution to the plasticity of beryllium.
