REVIEW ON WHROUGHT SUPERALLOY AND EQUIAXED CRYSTAL CAST SUPERALLOY MATERIALS AND THEIR APPLICATION BASIC THEORIES

Some application basic theories related to the research and development of wrought superalloys and equiaxed grain cast superalloys were reviewed simply.The main contents are wrought superalloys and mechanisms of effect of minor elements;equiaxed crystal cast superalloys and creep mechanisms;and hot-corrosion resistant superalloys and discovery of new phase transformation as well as interaction effect of creep-fatigue-environment.
