N18锆合金的氢致α/β相演化研究
Study of Hydrogen Induced α/β Phase Evolution in N18 Zirconium Alloy
【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。
【Abstract】 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 tem-perature was more affected by hydrogen than the higher one.It was easy to simulate the phase evolution in N18 alloy using the JMAK model.
