钛合金的蠕变行为是非常复杂的。通常蠕变行为可以分为低温蠕变、晶界滑移蠕变、扩散蠕变和位错蠕变等。
The creep behavior of ti alloys is complicated and can usually be divided into low temperature creep, grain boundary slip creep, diffusion creep and dislocation creep, so on.
退变质过程以黄铁矿变斑晶生长、矿石糜棱岩的形成、二次退火和化学再活化为特征。
Retrograde metamorphism at Hongtoushan is characterized by porphyroblastic growth of pyrite, formation of ore mylonite, secondary annealing and chemical remobilization.
在晶界上形成形态复杂稳定的碳化物能阻止空洞的连接，从而延长了蠕变第三阶段，增加了断裂时间。
The stable eutectic carbides with complex morphologyprevent coalescence of grain boundary voids and therefore prolong tertiary creep stage and rupture time.
