Dynamic Yield Strength and Spall Strength Determination for AerMet 100 Steels

摘要

Well-controlled impact studies have been conducted on 'as-received' and heat-treated AerMet 100 steel alloy samples to determine their dynamic material properties. In particular, gas gun and time-resolved laser interferometer have been used to measure the fine structure in the particle velocity profiles resulting from symmetric plate impact. Impact velocities ranged from 0.40 km/s to 0.90 km/s. These experiments have allowed us to estimate the dynamic yield and span strengths of the 'as-received' and heat-treated AerMet 100 steel.
