The invention relates to a processing method for eliminating the residual stress of the light alloy material, and is suitable for eliminating the quenching residual stress of various shapes and size light alloy materials. The method comprises the following steps of after quenching treatment, carrying out cryogenic treatment on the light alloy material; after subzero treatment, rapidly transferringthe light alloy material into a steam box for quenching heat treatment; and then carrying out air cooling to room temperature. The method disclosed is not limited by the size and shape of the material, the residual stress of the light alloy material is greatly reduced, and the strength and toughness of the light alloy material are synchronously improved.
