|Abstract:||The Weibull statistical model with three parameters has been used to assess the repeatability of the high pressure die-castings made by an Al-Mg-Si-Mn alloy. It was found that the round samples had a maximum Weibull modulus, indicating the best repeatability. The machined samples exhibited the second best of Weibull modulus. Among the square samples, the 2 mm thick samples had the lowest and the 5 mm thick samples had the highest Weibull modulus, indicating that the repeatability was worsened for the castings with thinner wall thickness. The microstructural uniformity and porosity levels are critical factors in determining the repeatability of high pressure die-castings.|
