Abstract为了研究激光辅助成形样件的疲劳性能及喷丸处理的作用规律,以2024铝合金板材为对象,对原始、激光辅助成形以及激光辅助成形后再喷丸等样件的微观组织、显微硬度、残余应力和拉-拉疲劳性能进行了对比分析研究。结果表明:激光辅助成形后,样件的组织和微结构未发现明显变化,但其硬度和残余拉应力水平有所下降;喷丸处理的激光辅助成形样件表层组织改变、显微硬度提高、其拉-拉疲劳寿命显著提高,不仅高于激光辅助成形样件,也高于初始样件。
Other AbstractWith the 2024 aluminum alloy plate as the main object,microstructures,microhardness,residual stresses and tension-tension fatigue properties of as-machined aluminum samples,laser aided forming samples and shot peening samples were studied.The results show that microstructures of laser aided forming sample were not varied obvious,but microhardness and extensive residual stress decreased;and surface microstructures were varied and microhardness was raised in shot peening samples.Shot peening can greatly improve fatigue properties.Tension-tension fatigue lives of shot peening samples were not only higher than laser aided forming samples,but higher than as-machined aluminum samples.
