Several advanced forming processes for nonferrous alloy sheets were introduced.Plastic forming technologies,especially warm forming processes,were developed for magnesium alloy,titanium alloy and aluminum alloy sheets.Magnesium alloy sheet warm forming process,thermal differential stamping process,sheet warm hydroforming process,sheet press forging process and warm stretch bending of magnesium alloy profile were presented.These processes had the perspective applications in the production of electrical,communication,computer sheet parts and automotive sheet parts.Sheet thermal stress forming process,hot bulge forming process,laser bending process and creep age forming process for titanium alloy parts were developed and used.As the increasing of aluminum alloy application,amount of high strength aluminum alloy with poor ductility and difficult forming was increased.The expansion of the application fields of them leads to the development of aluminum alloy sheet warm hydroforming process and press forging process.
