EFFECT OF COOLING RATE ON THE SOLIDIFICATION BEHAVIOR OF AC AlSi 7 Cu 2 ALLOY
2007
unpublished
This paper describes the effect of cooling rate on the size of the grains, SDAS and thermal characteristic results of the AC AlSi 7 Cu 2 cast alloy. The solidification process was studied using the cooling curve and crystallization curve at solidification rate ranging from 0,16 up to 0,71 C•s-1. It was determined that higher solidification rate increases the aluminum dendrite nucleation temperature and solid fraction at the dendrite coherency point, which implies that mass feeding is extended.
