TC4钛合金是国内外用量最多、使用范围最广的一种钛合金,已成功地在多种先进的航空发动机上得到了应用。国内装有TC4钛合金压气机盘和叶片的航空发动机,有些已经通过了长期地面试车,有些已经经历了一定时间的飞行考验。国外采用TC4钛合金做压气机部件的发动机也很多。 自行设计的某型涡轮风扇发动机一级TC4钛合金风扇盘示于图1a。本文通过对此盘榫槽部位裂纹(图1b)的分析,提出钛合金使用中
TC4 titanium alloy is the most used at home and abroad, the most widely used titanium alloy has been successfully in a variety of advanced aviation engines have been applied. Domestic aircraft engines equipped with TC4 titanium compressor discs and blades, some of which have passed long-term ground tests, have experienced some flight tests. Foreign TC4 titanium alloy compressor parts do a lot of engines. A self-designed turbo fan engine TC4 titanium alloy fan tray is shown in Figure 1a. In this paper, by analyzing the crack of mortise and tenon groove (Fig. 1b), it is proposed that titanium alloy should be used
