用示差扫描量热分析法研究了冷却速率对 Cu Zn Al Mn Ni记忆合金 Ms点的影响 .结果表明 ,在冷速为 1 5℃ / min至 5℃ / min及在 0 .2℃ / min至 0 .1℃ / min这两个区间内 ,Ms点变化均较小 .但冷速为 5℃ / min至 0 .2℃ / min时 ,Ms点下降幅度大
The effect of cooling rate on the Ms point of Cu Zn Al Mn Ni memory alloy was investigated by differential scanning calorimetry. The results show that at cooling rate of 15 ℃ / min to 5 ℃ / min and temperature of 0.2 ℃ / min When the cooling rate was 5 ℃ / min to 0.2 ℃ / min, the Ms point decreased greatly
