The influence of post-thermal treatments on microstructure and mechanical properties in A20X alloy fabricated through powder bed fusion
Abstract
This study compares the impact of two separate post-thermal treatments on microstructure and mechanical properties in novel Al-Cu-Ti based alloy (A20X) fabricated by the powder bed fusion additive manufacturing method. As-built samples of A20X were thermally treated by either undergoing solution heat treatment and ageing (T7) or hot isostatic pressing (HIP) and ageing. While both the heat treatment methods produced similar tensile properties, superior fatigue performance throughout the entire fatigue load range was obtained in the HIP and aging condition. A novel pore shape classification approach was developed to investigate the influence of each stage of the post-thermal treatments on porosity and individual pore shapes using X-ray microcomputed tomography. This novel approach uses existing pore shape classification techniques to not only categorise pore shapes but also quantify the volume associated with individual pores. It was found that the T7 procedure resulted in increasing internal defect density and altering the shape of pre-existing pores while HIP collapsed all the detectable internal pores of the as-built material prior to the aging process which led to the change in the shape of reopened pores. A detailed fractography analysis showed processing induced defects significantly influence fatigue life. Novel findings in this study provide a useful tool to determine the effects of different heat treatment procedures on the changes in unavoidable processing-induced defects and the mechanical properties, and to better understand the interdependency between pores and fatigue life in lightweight high-strength A20X alloy. The superior tensile and fatigue properties of this alloy with its high-temperature performance make A20X a desirable candidate for safety-critical aerospace applications.
