alloy can be achieved by addition of Al-Ti-B master alloys. The phases in Al-5Ti-1B master alloy have been studied by OM, TEM and EPMA analyses. The results show that the Al-5Ti-1B master alloy contains α-Al, TiB2 and Al3Ti. The effect of the Al-5Ti-1B master alloy on the grain refinement of A357 alloy has been gained. The mechanism of grain refinement in A357 alloy by Al-Ti-B master alloys is also......
formability for magnesium alloys. Recent results indicate that Sr additions such as Al-Sr master alloys that have been widely used in industrial practice especially for the modification of Al-Si alloys, 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......

Effects of various Mg-Sr master alloys on microstructural refinement of ZK60 magnesium alloy CHENG Ren-ju(程仁菊)1, PAN Fu-sheng(潘复生)1, 2, YANG Ming-bo(杨明波)3, TANG Ai-tao(汤爱涛)1 1...; Abstract: The effects of various Mg-Sr master alloys......
addition of Ti is believed to increase the grain refinement efficiency of Al4C3-containing Al-Ti-C master alloys in AZ31 alloy. Key words: Mg-Al based alloys; grain refinement; Al-Ti-C master alloys; Al4C3..., it is deduced that the size of Al4C3 particles in the Al4C3-containing Al-Ti-C master alloys is a key point for their grain refinement on Mg-Al based alloys, and the addition of Ti plays an important role......
