The Effect of ECAE on the Ballistic Response of AZ31
The equal channel angular extrusion (ECAE) process that refines the grains by severe plastic deformation has been noted to increase the high strain rate compressive strength of metals, such as magnesium alloy, AZ31. However it is not known if the improvement in the properties translates to improvement in the ballistic properties. In this study, ballistic experiments were performed on magnesium AZ31B that were ECAE processed by the 4Bc route. The targets were cut from orientations that exhibit disparate mechanical responses. The complex failure process was characterized by photonic Doppler velocimetry.
