| Abstract Scope |
The requirement for light weight in automative and aerospace applications has been the focus point in many studies. Lately, the effect of Rare-earth element addition to Al-Si alloys has begun to be investigated in detail. The aim is to establish higher tensile properties in thin sections. In this work, different ratios of Er, Eu and Dy were added to A356 alloy. T6 heat treatment was carried out with aging temperatures of 145, 160, 180 and 200C. 10 cylindrical bars were cast for statistical analysis. Weibull distributions were used to check the reproducibility of test results. It was found that Dy addition had made 356 more brittle while Er addition increased elongation at fracture. The toughness and reliability was found to be the highest in 0.1wt% Er added alloy. |
