| Abstract Scope |
The residual stresses formed during the casting process can vary in size and distribution depending on their interaction with the microstructure, which directly affects the reliability of the product. In this study, the surface residual stresses of aluminum alloys manufactured by High Vacuum Die Casting (HVDC) were measured by a portable XRD instrument (ì-X360s) and compared with the residual stress prediction simulations to evaluate the agreement with the measured values. In addition, a Design of Experiments (DOE) was performed with the von Mises stress change after grinding as the response variable and microstructure characteristics (area fraction, average diameter, and sphericity of the á-Al phase) as the main factors. After evaluating the statistical significance of each factor, the correlation between residual stress and microstructure was analyzed. |
