Description

technical field [0001] The invention relates to the technical field of automobile stamping dies, in particular to an energy-saving heat treatment method for automobile stamping dies. Background technique [0002] Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called cold stamping die (commonly known as cold stamping die). Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. [0003] When the aluminum alloy is quenched and heated, vacancies are formed in the alloy. During quenching, due to the rapid cooling, these vacancies are "fixed" in the crystal before they can be removed. Most of these vacancies in supersaturated solid solutions are combined with solute atoms. Since the supersaturated solid solution is in an ...
