摘　　要：论述了GH 132合金在540℃下的蠕变行为及蠕变寿命的可靠性统计分析。试验指出,通过多次时效处理可以提高合金的蠕变延性,改善合金的缺口敏感性。The creep behavior of superalloy GH132 at 540℃ after different aging treatments and statistical analyses of reliability on creep life were described in this paper. The tests shown that the creep ductility were increased and the notch sensitivity of alloy were improved through multiple aging treatments.

关 键 词：合金 蠕变 缺口敏感性 可靠性
