, were thought as an effective means of grain refinement for Mg-Al series alloys[5-7]. For example, SRINIVASAN et al[8] and NAM et al[9] reported that adding Al-10Sr master alloy to a Si-containing... phases in Al-Sr master alloys (for a given alloy in contact with the melt for a given time), thereby enhancing the efficiency of modifiers, and this refinement of Al4Sr phases could be achieved......
was fabricated by LSM Company of England. The AZ61 alloy was prepared by melting pure Mg (99.9%, mass fraction), Al (99.9%, mass fraction), Zn (99.95%, mass fraction) and Al-10Mn master alloy in an electrical...% addition of Al5Ti1B.

was discussed. When the liquid aluminum-magnesium was used as the reductive agent, the all-recovery exceeds 80% and the concentration of Sc in master alloy prepared exceeds 1.9%. The best reducing reaction...Preparation of Scandium-Bearing Master Alloys by Aluminum-Magnesium Thermoreduction 尹志民1,白兰1,姜锋1 (1.Institute of Materials Science and Engineering, Central South University, Changsha 410083, China......
Grain refinement of AZ31 magnesium alloy by new Al-Ti-C master alloys HAN Guang(韩 广), LIU Xiang-fa(刘相法), DING Hai-min(丁海民) Key Laboratory for Liquid-Solid Structural Evolution... through the reaction Ti(solute)+Al4C3(s)→TiC(s)+Al(l). With the addition of 1% Al-1Ti-1C master alloy, the average grain size of AZ31 is reduced sharply from 850 μm to 200 μm, and the grain......
Grain refinement of AZ31 magnesium alloy by Al-Ti-C-Y master alloy许春香,卢斌峰,吕正玲,梁伟摘 要:Al-Ti-C-Y master alloy was prepared by combining SHS technique... master alloy consisted of α-Al, TiAl3, TiC and Al3Y phases, and exhibited good grain-refining performance of AZ31 alloy. Morphology of α-Mg changed from coarse dendritic to fine equiaxed......
Grain refinement of hypoeutectic Al-Si alloy preparedwith ELTA by Al-4B master alloy WANG Ming-xing(王明星), MENG Xiang-yong(孟祥永), LIU Zhi-yong(刘志勇),LIU Zhong-xia(刘忠侠), WENG Yong-gang(翁永刚), SONG Tian... in the hypoeutectic Al-Si alloy prepared by using ELTA was investigated, and compared with those of Al-5Ti, Al-5Ti-1B and Al-4B master alloys in the similar alloy prepared by using pure Al. The results indicate......
