一、前言振动时效具有消除残余应力,稳定金属零件尺寸的作用,与热时效相比具有节约能源、降低成本、提高生产效率、改善劳动条件、设备简便、易于操作、便于实现机械化自动化等优点,常用于铸、锻、焊等黑色金属和有色金属构件的处理。1906年美国首次发表了振动消除应力专利。然而,对振动消除应力的机理研究工 I. Introduction Vibration aging has the effect of eliminating residual stress and stabilizing the size of metal parts, saving energy, reducing costs, improving production efficiency, improving working conditions, Commonly used in casting, forging, welding and other ferrous metals and non-ferrous metal components. The United States for the first time in 1906 issued a vibration elimination stress patent. However, the mechanism of vibration stress relief workers
