影响钛合金蠕变行为的因素分析

Factor Analysis on Creep Behavior of Titanium Alloys

摘要:

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，扩散蠕变和位错蠕变等。一些得要的内外因素，如温度，组织结构等对钛合金的蠕变性能都有影响，且对不同蠕变类型其影响也不同。本文主要综述和分析了蠕变参数，组织结构，合金元素硅等对钛合金位错里面变行为的影响以及提高蠕变阻力的各种可能机制。

Abstract:

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. Some important factors, such as temperature, time and microstructure, influence the creep property of Ti alloys due to the different creep types. This paper reviews the effects of creep parameters, microstructure, and Si element on the dislocation creep behavior of Ti alloys, and the possible mechanism of improving the creep resistant of alloys are also discussed.
