ABSTRACT: For the local defects such as thinning and thickening in the process of hot stamping of titanium alloy shells, the evolution process, mechanism and causing thinning of the equivalent stress strain at different casting temperatures are analyzed, and the results show that the equivalent stress after forming decreases with the increase of temperature and the minimum thinning is at 800˚C. It is necessary to formulate a reasonable stamping and turning process for the hot stamping forming of large diameter thin-walled titanium alloy, and the hot treatment after stamping forming is very necessary; a reasonable turning process can improve the qualified rate of finished products.
