摘要
本文探讨了CuZnAl合金相变过程中内耗的变化规律、产生机制以及加热速度对内耗的影响。结果表明:CuZnAl合金高内耗的产生是由其特有的相变机制引起的,并和加热速度有关。
The variety and mechanism of internal friction of CuZnAl shape memory alloy in shape transformation,and the influence of heating rate on internal friction are experimentally studied in this paper.The results show that the high internal friction of CuZnAl alloy attributes to its special phase transformation nature,and also depends on heating rate.
