各種熱處理に伴う殘留應力の研究(第7報)析出に伴ふ殘留應力について

The cooling stress restored in quenched Ag-Ca alloy is released as the precipitation due to continued aging, the faster the aging temperature elevates. In the case of AI-Cu alloy, the residual stress slightly increased at first up to the period of the formation of the cluster and then gradually decreases up to the precipitation of the θ phase, no sign corresponding to the formation of θ'.
