振动时效技术,从本世纪六十年代问世以来,已有近30年的历史。与传统的自然时效、热时效相比,虽然它还是较年青,但具有广泛应用前途。 1.振动时效概述振动时效可以降低、均化铸造件、焊接件、锻造件的内部残余应力,提高工件的综合 Vibration aging technology, since the advent of the sixties of this century, has nearly 30 years of history. Compared with the traditional natural aging, thermal aging, although it is still relatively young, but has a wide range of applications. 1. Vibration Aging Overview Vibration aging can be reduced, the homogenization of casting, welding parts, forging internal residual stress and improve the synthesis of the workpiece
