Title
Effects of Solidification Rate and Quenching Temperature on the Microstructures of Hypereutectic Al-Si Alloy
이정무 , 강석봉 Jung Moo Lee , Suk Bong Kang
Abstract
Effects of solidification rate and quenching temperature on the microstructures were investigated in hypereutectic Al-Si alloy. In the phosphorus-treated alloy the primary silicon size reduced with increasing solidification rate in the range of 0.6-10℃/sec, while in the non-treated alloy it was not sensitive to the solidification rate in the same range. There exhibited a transition point of primary silicon size with quenching temperature during the solidification of hypereutectic Al-Si alloy.
