Abstract
A manufacturing method according to one aspect includes performing a first process of refining crystal grains of the metal member, performing a second process of releasing residual stress of the metal member after the first process, and performing a third process of applying residual stress to the metal member after the second process.
Claims8
A manufacturing method of a metal member with residual stress, the manufacturing method comprising:
- plastically deforming the metal member to refine crystal grains of the metal member;
- heating the metal member so as to maintain the refined state of the crystal grains to release residual stress of the metal member after the crystal grains of the metal member are refined;
- and
- performing a laser peening, a cavitation peening, a water jet peening, or a low plasticity burnishing (LPB) to apply residual stress to the metal member after the the metal member is heated.
