合金材料位错物理应用之高温合金通用公式、系统验证与成分设计

Abstract

本文是“合金材料位错物理”理论框架的首篇应用成果。从位错物理的核心方程出发,系统推导了高温合金(特别是镍基单晶高温合金)的通用性能预测公式,涵盖γ相强化、固溶强化、蠕变寿命四大核心性能。基于18种典型高温合金(含CMSX-4、René N5、DD6、IN738、IN740H、GH3536、CM247LC等)的实验数据,对公式预测精度进行系统验证。结果表明:室温屈服强度平均绝对误差28MPa(相对误差3.2%),760℃屈服强度平均绝对误差35MPa(相对误差3.8%),1100℃/137MPa蠕变寿命预测误差大部分在±15%以内。与现有预测方法相比,本公式具有物理意义清晰、参数数量少、无需大量实验拟合的优势。基于该公式,进一步给出两个新配方——低Re单晶合金CSU-LRe1和铸造多晶合金CSU-LC1,并提供实验室制备工艺参数。
