Abstract： The sound velocities along the release path of annealed LY12-Al are measured by using a velocity interferometer system for any reflector (VISAR) technique. The shear modulus and yield strength are then obtained. Comparison of the experimental results with those of unannealed LY12-Al shows that anneal has little influence on sound velocities and shear modulus though it weakens the yield strength considerably, and changes the dependence of yield strength upon shock stress. The ratio of shear modulus to yield strength of unannealed LY12-Al increases with shock stress monotonically while that of annealed LY12-Al exhibits much more complicated behaviour.
