Abstract:

High temperature alloys were important materials for key components of aircraft engines, and shot peening was a critical step in the manufacturing process of blade parts. Through the high-speed impact of the projectile on the surfaces of the workpieces, residual compressive stress might be introduced to the surfaces, thereby offsetting some working loads and improving the fatigue performance of the components. Therefore, studying the shot peening processes of high-temperature alloys was of great significance for improving the service performance and reliability of key components in aircraft engines. This paper introduced the research status of high-temperature alloy shot peening processes in terms of simulation methods, surface integrity of high-temperature alloy shot peening, and fatigue performance of high-temperature alloy shot peening. Finally, the shortcomings of existing research and future research directions were analyzed.

Key words: high temperature alloy, shot peening, surface integrity, fatigue performance

摘要:

高温合金是航空发动机关键构件的重要材料,喷丸加工是叶片类零件工艺过程的关键环节,通过弹丸在工件表面的高速撞击,能够在表层引入残余压应力,从而抵消部分工作载荷,提高构件的疲劳性能,因此,研究高温合金喷丸工艺对改善航空发动机关键构件的使役性能与可靠性有重要意义。针对喷丸工艺模拟方法、高温合金喷丸表面完整性和高温合金喷丸疲劳性能三方面的研究成果,介绍了高温合金喷丸工艺的研究现状,分析了现有研究存在的一些不足,并指出了未来的研究方向。
