HEAT TREATMENT OF ADDITIVELY MANUFACTURED ALUMINUM ALLOY

Abstract:

A method for heat treating an additively manufactured A205 aluminum alloy component ("AM205 component") to produce a uniform grain distribution within the AM205 component is disclosed. The method includes solution aging the AM205 component at a first temperature for a first time period, wherein the first time period is less than five hours and overaging the AM205 component after the solution aging.
