Abstract (en)
This invention relates to a method for manufacturing a light metal forging material provided as a material to be subjected to a forging process for obtaining a light metal forged member, by charging a light metal molten material into the molding cavity of a specified molding die so as to form a forging material and subjecting the forging material to a specified heat treatment before the forging process, there is generated a blister attributed to internal gas expansion in the material, thereby, in obtaining a finished product made of light metal by forming a forging material and forging the material, a blister associated with heat treatment is reliably prevented from being generated in a product (forged member) through this forging process. <IMAGE>
