Dynamic Properties of LY-12 Aluminum AlloyIts Punching Shear Fracture Strength at High Temperatures
-
摘要: 本文介绍LY-12铝合金从常温到400 ℃高温下,动态冲塞剪切破坏强度的测试及研究结果,并给出了该种材料静态压剪破坏强度的测量结果。在上述温度范围内,LY-12铝的动态冲塞剪切破坏强度与其静态结果之比为1.3∶1~4∶1,表明随着温度的升高,动态的强度远大于同温度的静态结果。Abstract: This paper describes the measurements of the punching shear fracture strength of LY-12 aluminum alloy from room temperature to 400 ℃, and the static shear strength in the same temperature range. The ratio of the dynamic punching shear to the static is about 1.3∶1 at room temperature to 4∶1 at 400 ℃. It shows that the high temperature dynamic strength is considerably higher than that of static.
