Abstract

The method for manufacturing a plastic worked article includes the steps of shaping an article for plastic working by a semisolid molding in which molten metal including both a solid phase and a liquid phase is introduced into a die; performing a pre-plastic working heat treatment on the article for plastic working for causing blisters by expanding gas cavities included in the article for plastic working; and forming a plastic worked article by plastic working the article for plastic working after the pre-plastic working heat treatment. The plastic working of the article for plastic working is performed in such a manner that a tensile stress applied direction at a tensile stress applied portion to which tensile stress is principally applied in actual use of the plastic worked article substantially accords with a plastic flow direction at a portion of the article for plastic working corresponding to the tensile stress applied portion.
