Abstract
An object of the present disclosure is to provide a method for manufacturing an aluminum alloy plastically-processed article, capable of preventing a burning crack from occurring due to processing heat generated during plasticity processing while maintaining a solution-treatment temperature of an aluminum alloy material for ensuring a mechanical strength thereof. A method for manufacturing an aluminum alloy plastically-processed article, includes a step of performing a solution treatment for an aluminum alloy material by heating and maintaining the aluminum alloy material at a solution-treatment temperature, a step of performing plasticity processing for the aluminum alloy material subjected to the solution treatment, and steps of cooling the plastically-processed aluminum alloy material at a time at which the step of the plasticity processing is completed, and aging the cooled aluminum alloy material. The method further includes pre-plasticity-processing cooling step of cooling the aluminum alloy material subjected to the solution treatment.
