Effects of Hydrostatic Pressure on Solidification Phenomena of Al-Si binary alloys(I);Metallurgical Study
Al-Si이원계 합금의 응고현상에 미치는 정수압의 영향(I);금속 조직적 연구
Abstract
The effects of pressure during solidification on macro-and micro-structures have been studied in pure aluminium and Al-Si alloys. The application of pressure during solidifcation accelerated both equiaxed and columnar dendritic-growth due to stimulating of equiaxed survival and faster preferential growth of primary dendrites against the parallel direction of heat flow. Burden-Hunt model was modified to express the significant changes of CET behaviours under pressure. A further point to be noted was that greatly fine eutectic silicon flakes (
