The effects of Al3Ti4B master alloy on microstructure, mechanical and corrosion resisting properties of Mg-7Al-0.4Zn-0.2Mn alloys were studied. The results show that the average grain size of alloy decreases when the addition of Al3Ti4B is less than 0.3%(mass fraction). The microstructure is refined remarkably when adding 0.3% Al3Ti4B, the average grain size decreases from 135 to 30μm. When the Al3Ti4B addition is more than 0.3%, the grain size increases with the increase of Al3Ti4B. The… CONTINUE READING
