Abstract

See full text

This method for setting aging conditions is provided with: a step for acquiring a master curve (20) indicating the relationship between an aging condition parameter and a material strength parameter by executing an aging process on a standard material; a step for acquiring a fitting point (A) indicating the value of the material strength parameter of a subject material of which the chemical component parameters and/or metal structure parameters differ from those of the standard material; a step for acquiring a corrected aging curve (30) by correcting the master curve (20) in a manner so that a portion of the master curve (20) corresponds to the fitting point (A); and a step for setting aging conditions for the subject material on the basis of the corrected aging curve (30).
