Abstract:

Based on the analysis of distortion reason of aluminum alloy precision parts and the comparison of conventional methods of eliminating residual stress, one of the ideal methods to eliminate residual stress by cryogenic treatment was proposed. The effect of cryogenic treatment on residual stress and dimensional accuracy of blank ware investigated. The results show that cryogenic treatment can effectively eliminate residual stress and improve dimensional stability.

Key words: cryogenic treatment, aluminum alloy precision parts, distortion, residual stress
