Study about the phase structure of titanium alloy material used in semi-armor piercing warhead

Referring to the bumping experiment data, the dynamic yield pressure and phase structure of the titanium alloy material used in warhead is analyzed from macroscopical side and microcosmic side. Some conclusions are gained that the dynamic peak yield stress and side direction expansion is bigger with the strain rate increasing, the section becomes more nonuniform, the cut brim becomes apparent, the gradient is bigger and the damaged area enlarges within longer distance.
