英文摘要	In this paper, a sery of (Ti0.5Ni0.5-xZrx)80Cu20(x=0, 0.02, 0.04, 0.06, 0.08) was successfully achieved in the levitation melting and water-cooling copper suction. We have prepared amorphous composite materials with continuous organization gradient through the control of Zr addition amount and studyed its structure and mechanical behavior and influence of trace of Zr adding to structure and mechanical behavior of amorphous composite materials. The results show that the temperature gradient of solidification process determines the temperature gradient of composite materials, from surface to center mainly for the amorphous phase, martensite phase and austenitic dendrites. It has precipitated the B2-Ti(Ni, Cu) supercooled austenite phase and the B19'-Ti(Ni, Cu) thermal induced martensite phase on as-cast amorphous substrate. Stress induced martensite phase transformated after adding loads. Diffraction peak of martensite gets stonger than when it was as-cast and martensite prefers orientation. This series amorphous alloy's amorphous formation ability reduces after increaseing firstly and austenite's contents was declining and transformation induced plasticity decreases, so the plastic was getting low and the intensity reduces after increaseing firstly. © 2015, Chongqing Functional Materials Periodical Press Co.
