The effect of trace Sc on the quench sensitivity of AL–7Si–0.6 Mg alloys

The Jominy end quench test has been adopted to investigate the effect of trace scandium on the quench sensitivity of Al–7Si–0.6 Mg alloys. The results show that at a lower quenching rate, the preferred precipitation of the Al3Sc phase inhibits the formation of a β′-Mg2Si phase, promoting the nucleat...
