【摘要】 研究了锆２、锆４合金管材在高压釜内氢氧化锂溶液中，于３６０℃、１８６ＭＰａ条件下进行不同时间的渗氢后试样的吸氢特性。试样的吸氢变化具有锆合金氧化增重类型的特点，即抛物线型的变化和转折点，另外还显示了氢氧化锂溶液的浓度对吸氢量（１００ｍｇ／ｋｇ以下）有明显的影响。更多还原

【Abstract】 Hydrogen absorption in lithium hydroxide water solution for zircaloy2 and zircaloy4 was investigated under condition of 360/18.6 MPa in autocave test. The results show that the hydrogen absorption kinetics has the same characteristic as that of the alloys oxidizing weight gain, i.e., the parabolictype transition and a transition point. The concentration of lithium hydroxide has remarkable influence on the amount of hydrogen absorption (<100 mol/L).更多还原
