Research of Burn Mechanism and Testing Method of Titanium Alloy

摘要: 研究了飞机用BT20和OT4钛合金材料烧伤后力学性能和电导率随烧伤温度及烧伤时间的变化关系。分析了使用电导率法和硬度法检测钛合金烧伤程度的特点。试验结果表明，钛合金的电导率、硬度和强度均与烧伤温度和烧伤时间呈一定关系，因此可通过测定电导率和硬度的方法确定钛合金的烧伤程度。

Abstract: The relationships between mechanical property and conductivity of titanium materials used in a plane varied with burning temperature and time were researched. The characteristics of burning extent with conductivity testing method and hardness testing method were analyzed. Testing result showed that there were sorne certain relationship between the conductivity and hardness with the burning temperature and burning time, so it was possible to identify the burning extent with conductivity testing method and hardness testing method.
