Effects of vibration and grain refiner on microstructure of semisolid slurry of hypoeutectic Al-Si alloy ZHAO Jun-wen(赵君文), WU Shu-sen(吴树森), XIE Li-zhi(谢礼志), AN Ping(安 萍), MAO You-wu(毛有武) State... of vibration and grain refiner on the microstructure of semisolid slurry of hypoeutectic Al-Si alloy were studied. The impact of vibration on the convection of liquid was conducted by using a system......
, of the cooling slope on the process to make semisolid slurry were investigated. The results show that these factors affect the behaviors of the semisolid slurry on the cooling slope. The tilt of the slope is the factor that has major influence on the behavior of the semisolid slurry. The cooling roll is developed from the result of the research of the cooling slope. The rotating cooling roll can......
Fabrication of AZ61-1.0%Y antiburning magnesium semisolid slurry ZHAO Ming-juan(赵明娟)1, 3, ZHAO Long-zhi(赵龙志)1, 2, 3, ZHOU Bing-feng(周冰峰)2, YAN Hong(闫 洪)2 1. Key Laboratory of Ministry... of the semisolid slurry was characterized by a metallography microscope. The results show that the fine circular solid phase distributes uniformly in the slurry when the stirring temperature ranges from 600......
