外文摘要：A novel melting infiltration by ultrasonic vibration was investigated and applied to fabricate Ti6A14V(TC4)lattice structure-reinforced Mg-10Gd-2Y-1Zn-xZr(refer to VW92 hereafter,x=0,0.5 wt％)alloy matrix composites.The edge-to-edge matching model indicates that the well-matching and possible orientation relationships(ORs)between the α-Mg and α-Ti,[10-10]α-Mg//[11-23]α-Ti in(0002)α-Mg//(10-10)α-Ti possesses the smallest misfit of 0.4％(fr),and thus the α-Mg grains can nucleate on the TC4 lattice structure.Interfacial reaction occurred in the TC4/VW92+0.5 wt％Zr composites,and the reac-tion product was confirmed to be Al2Zr3,AlZr2 and α-Ti(Zr)particles formed by continuous solution of Zr-Ti.Among the interfacial products,the AlZr2 phase is a brittle phase with high-volume fraction,which is not conducive to the load transfer.But generally speaking,the α-Ti(Zr)and the α-Mg tend to form a coherent interface,which is beneficial for improving the interfacial bonding strength of composites.
