Grain Refining Efficiency of SHS Al-Ti-B-C Master Alloy for Pure Aluminum and Its Effect on Mechanical PropertiesXu-Guang An1,Ying Liu1,2,Jin-Wen Ye1,Lin-Zhi Wang1,Peng-Yue Wang11. School... master alloy was successfully prepared by self-propagating high-temperature(SHS)reaction from an Al-Ti-B4C system with molten Al.Microstructure and phase characterization of the prepared......
January 2010 Abstract: Al-5Ti-1B master alloy was added into Mg-14Li-1Al (LA141) alloy and then LA141 sheets were prepared by extrusion and cold rolling. The effect of the addition level of Al-5Ti-1B... and plastic formability of the LA141 sheets. The results show that the optimal addition level of Al-5Ti-1B master alloy into LA141 alloy is 1.25% (mass fraction) and LA141 alloy has the finest grains......
effects of Fe in Al alloys. In general, Ni is added to Al alloys in the form of Al-Ni master alloys. So Al-Ni master alloy is very important material. Metal nickel has useful bulk properties such as good electrical conductivity and fracture toughness. So it is ideal anode materials to produce Al-Ni master alloy. If Al-Ni master alloys were successfully produced in industrial cell using Ni-based......
