摘要
本文介绍LY-12铝合金在常温至400℃动载下(应变率为 10~3/秒),屈服强度的测试及研究。采用一维Hopkinson压杆实验装置及管式高温炉。利用一维应力波传播理论及应变片直接测量两种方法,得到了LY-12铝合金的屈服强度随温度变化的曲线。
This paper introduces the yield strength measurement of LY-12 aluminium alloy under dynamic loading in temperature interval from room temperature to 400℃.This research utilizes one dimensional split Hopkinson pressure bars and the tubular furnace. The average stress-strain curves of specimens can be measured under different temperature conditions based on one dimensional theory of stress wave propagation and thier stress - strain curves also can be detected by strain gages directly. The yield strength and yield strength temperature curve can be obtained.
