用冲击能量法,对低延性SiC颗粒增强铝基复合材料得到冲击能外还得到动态屈服载荷、最大载荷、失稳载荷以及应变等多种参量,综合分析了温度对各种参量的影响,提出了总能量与温度关系曲线上的第一峰可作为低延性材料的最佳使用温度。

In this paper, these parameter, impact energy, yield stress, maximum stress, and strain have been obtained using impacting energy testing for SiCp reinforced aluminum matrix composites with low ductility. Effect of temperature on these parameters has been analyzed, and it has been suggested that the first peak value in relationship curve about total energy and temperature are acted as the optimum used temperature.
