Influence of Composition and Breaking Process on Microstructure of Al-Fe-V-Si Heat Resistant Aluminum Alloy

摘要

Alloy composition of thin strip Solidification Microstructure Effects of larger, Al-8.5Fe-1.4V-1.7Si and Al-11.7Fe-1.15V-2.4Si alloy. At 20 m/s and wheel line speed and 0.7 × 105Pa jet pressure difference process thin slices of tissue, can see in addition to changes in grain size and a-Al grain accounts for the proportion also vary. The Al-8.5Fe-1.4V-1.7Si alloying degree is relatively low, the alpha -Al grains occupy more volume fraction, while the Al-11.7Fe-1.15V-2.4Si alloy alpha-Al grain volume fraction is relatively small.
