| 摘 要： | 本文利用DSC（差示扫描量热仪）、热膨胀法、共振法研究稀土Ce对超低膨胀合金马氏体相变温度的影响，并对3种方法测试结果加以比较。研究发现，3种相变温度测试方法所得出的实验规律一致，即添加适量Ce，能降低超低膨胀合金的马氏体相变温度，有助于提高超低膨胀合金的低温组织稳定性。热膨胀法和共振法所测得结果较为接近，两者的测试结果较DSC法所测得的结果更准确。

| Abstract: | The influence of cerium on the martensitic transformation temperature of Super-Invar alloy was investiga- ted by DSC, thermal dilation method and resonance method. It is found that the experimental laws are identical with results by the three methods of martensitic transformation temperature measuring. The additon of appropriate ceri- um will decrease the martensitic transformation temperature of Super-Invar alloy and increase the cryogenic structure stability of Super-Invar alloy. The results obtained by thermal dilation method and resonance method are similar. The Ms temperature obtained by thermal dilation method and the resonance method is more reliable than DSC re- sults. |
