ECAP加工对SiCp/ZL108铝基复合材料韧性的影响
Equal-Channel Angular Pressing of PMMC: Effect on toughness
本文采用等通道转角挤压对6%SiCp/ZL108铝基复合材料进行加工，研究其常温和低温冲击韧性。研究结果表明，经过ECAP挤压6道次试样，其低温冲击韧性，在20°C到0°C温度范围内，随温度的降低而下降，在0°C到-35°C温度范围内，随温度的降低而升高。经ECAP加工后的复合材料，冲击韧性为11.9J/cm2，是未经ECAP加工复合材料冲击韧性（1.3J/cm2）的9倍。
Equal channel angular pressing (ECAP) was applied to the 6%SiCp/ZL108 composite, and the impact toughness at ambient temperature and at low temperature were investigated. The results showed that the impact toughness of composite which was processed 6 passes, was decreased with the depressed temperature from 20°C to 0°C, and was elevated from 0°C to -35°C. The impact toughness of as-cast sample is only 1.3J/cm2, but the impact toughness increased to 11.9J/cm2 after processing 5 passes by route C.
