Abstract: An aluminum alloy plate includes peritectic elements and Mg. Wherein plate thickness of the plate is represented as t (mm), a range within ±0.01×t from t/2 is represented as a central portion, a range within ±0.01×t from t/4 is represented as a quarter portion, and a range within 0.02×t from a top surface in the plate thickness direction is represented as a superficial portion, concentration of the peritectic elements is such that a concentration difference between in the central portion and in the quarter portion, and a concentration difference between in the central portion and in the superficial portion are 0.04% (mass %) or less. In addition, concentration of the Mg is such that a concentration difference between in the central portion and in the quarter portion, and a concentration difference between in the central portion and in the superficial portion of the plate thickness are 0.4% or less.

Abstract: The present disclosure relates to a method for producing an aluminum alloy rolled material for deformation molding, the method including: a step of performing homogenization treatment of an ingot including an aluminum alloy with predetermined composition; a step of cooling the aluminum alloy after the homogenization treatment so that an average cooling rate in an ingot thickness of ¼ part from 500° C. to 320° C. is 30° C./h to 2000° C./h; and a step of starting hot rolling at 370° C. to 440° C. and winding the hot-rolled aluminum alloy at 310 to 380° C., in which the method for producing an aluminum alloy rolled material for deformation molding further includes a step of retaining the aluminum alloy after the cooling step for 0.17 hours or more at a heating temperature before rolling set within a range of 370° C. to 440° C. before the hot rolling.

Abstract: In accordance with a program, a processor obtains a plurality of manufacturing parameters and a measured value of an at least one property of an alloy material, calculates a pre-predicted value based on a first manufacturing parameter included in the plurality of manufacturing parameters using a prediction expression describing a relationship between the first manufacturing parameter, and a pre-predicted value of the property representing a roughly calculated value of a target predicted value that is a target value of the property, calculates a difference between the pre-predicted value and a measured value of the property, and trains a model using a training data set including a second manufacturing parameter and the difference, to generate a trained model that is used to predict the at least one property.
