Influence of strain rate on deformation mechanisms of an AZ31 magnesium alloy
Original language description
The paper reports mechanical properties of magnesium alloy AZ31 deformed at low and high srain rates. Material was prepared using squeeze casting technology. Compresion test were deformed at an initial strain rate of 0,000083 1/s at temperatures betweenroom temperature and 300 grad.Celsius. Dynamic compression Hopkinson test were carried out at room temperature with impact velocities ranging from 11,2 to 21,9 m/s. Transmission electron microscopy investigations showed significant dislocation and twinsdensities. Results are discussed considering the importance of the activation volume determined in the stress relaxation tests obtained at the low strain rate and quite separately, the importance of adiabatic shear banding at hihg strain rates.
