MANUFACTURING METHOD OF HIGH STRENGTH ALUMINUM ALLOY LAMINATE MOLDED BODY
Document Type and Number:
Japanese Patent JP2017155291
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for manufacturing an aluminum alloy laminate molded body capable of being supplied to practical uses by controlling temperature during lamination to make high strength.SOLUTION: There is provided a method for manufacturing an aluminum alloy laminate molded body by laminating a raw material metal powder consisting of an alloy containing aluminum as a main metal by a lamination method. During lamination of the raw material metal powder, overaging temperature Trepresenting maximum hardness of an aging curing curve is calculated by using the aging curing curve representing changes of hardness of the laminate by lamination temperature, which is made per lamination time when lamination is completed, and lamination temperature is maintained constant in a temperature range of 0°C or (T+20°C) through lamination or the lamination temperature is changed in a temperature range of 0°C or (T+20°C).SELECTED DRAWING: Figure 2
