| Abstract: | In this study, the effect of melt quality and quenching temperature on the mechanical properties of 2024, 6063 and 7075 was investigated. The alloys were produced by Strain Induced Melt Activated (SIMA) method. T6 heat treatment was carried out by quenching in two different temperatures: 20 °C and 80 °C. Scanning electron microscope analyses were carried out on the fracture surfaces. In addition, reduced pressure tests were carried out to correlate the mechanical test results with metal quality. The results were analysed by Weibull statistics. It was found that samples quenched at 80 °C showed better mechanical properties and there was a good correlation between bifilm index and Weibull distributions. |
