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 nucleation of finely dispersed metastable Mg2Si precipitates in the subsequent aging treatment. The quench...
The 356 alloys which are different in the composition of Sr and Fe elements were heavily deformed by equal channel angular extrusion. The large acicular silicon in the unmodified alloy and the Fe-bearing phases act as crack initiators and provide easy paths for fracture. After extruded for 5 passes, the acicular silicon and Fe-bearing phases are obviously refined and rounded, both of which resulted...
