本文件建立了一个测试程序，用于确定飞机涡轮发动机清洁和维护材料导致钛合金零件应力腐蚀开裂的倾向性。通过确定与清洁和维护材料接触对预应力钛合金在随后加热至高温时开裂倾向的影响，对具有代表性的钛合金进行评估。

This document establishes a test procedure for determining the propensity of aircraft turbine engine cleaning and maintenance materials for causing stress-corrosion cracking of titanium alloy parts. The evaluation is conducted on representative titanium alloys by determining the effect of contact with cleaning and maintenance materials on tendency of pre-stressed titanium alloys to crack when subsequently heated to elevated temperatures.
