摘　　要：用Setaram Multi HTC高灵敏热分析仪在准平衡和动态两种情况下对一组经过电解渗氢/均匀化退火处理的N18锆合金的相变进行了研究。结果表明,随着氢含量的增加,N18的α/β相转变温度逐渐降低,并且β相转变越多,氢含量的影响越小;用JMAK模型可以很好地模拟氢对N18合金相演化过程的影响。The transformation behavior of N18 alloy with and without hydriding was investigated using Setaram Multi HTC high-temperature and high-sensitivity calorimeter. The results showed that the α/β phase transformation temperatures decreased with the increase of the hydrogen content, and the lower transus temperature was more affected by hydrogen than the higher one. It was easy to simulate the phase evolution in N 18 alloy using the JMAK model.
