摘要
Abstract
The K2ZrF6 was used as modifiers for the modification of ZL114A alloy,the microstructure and tensile properties of as-cast and T6 ZL114A alloy with different pouring temperature and cooling rate were investigated.The results show that modification of ZL114A alloy is the best at 710～720 ℃ pouring and with metal mold,α-Al matrix is mainly a larger isometric grains,most of the eutectic silicon is fine fibrous or short rod.关键词
