Effect of Ti on the properties of Zr55Cu30Al10Ni5 amorphous alloy
The effects of Ti addition on the thermal stability and mechanical properties of Zr55Cu30Al10Ni5 based alloy were studied.The results show that Zr55Cu30Al10Ni5 can be improved by adding an appropriate amount of Ti element.The thermal stability and amorphous forming ability of Zr55Cu30Al10Ni5 amorphous alloy.With the increase of Ti element content(x=0,0.5,1,1.5,2,2.5),the thermal stability of Zr55Cu30Al10Ni5 amorphous alloy increases first and then decreases.When x=2,the amorphous forming ability of the amorphous alloy is the strongest.The proper addition of Ti is also beneficial to improve the hardness,compressive fracture strength and plastic deformation ability of Zr55Cu30Al10Ni5 sample.When x=2,the hardness of the amorphous alloy reaches 533.56.With the increase of Ti element content,the strength and plasticity of the amorphous alloy increase first and then decrease.When x=0.5,the breaking strength of the amorphous alloy is 2 111 MPa,and the plasticity is 5.02％,which is 1.8 times the plasticity of the amorphous alloy without Ti element.
