Effects of Ti Addition on Properties of Zr-Cu-Fe-Al Amorphous Alloy System
The bulk Zr65-xTixCu20Fe5Al10(x=0,2,4,6,8)alloys with ϕ2 mm were prepared by injection copper mold casting.Effects of Ti addition on the amorphous forming ability and mechanical properties of Zr65-xTixCu20Fe5Al10(x= 0,2,4,6,8)alloy system were investigated by X-ray diffraction,differential scanning calorimeter,compression tests and scanning electron microscope.The results indicate that the alloy achieves optimal amorphous forming ability when x=2,where the supercooled liquid zone ΔTx,the reduced glass transition temperature Trg,the amorphous form-ing capacity parameter γ,the compressive strength,and the plastic deformation are 73 K,0.564,0.401,1 905 MPa and 12%,respectively,and the compressive strength and plastic deformation ability are desirable,which is attributed to the formation of a large number of shearing bands.
