Study on liquid structure feature of Al100-xNix alloy with resistivity and rapid solidification method

In this paper, the liquid structure of Al100 - xNix alloys (x = 0, 2, 2.7, 5) was mainly studied with resistivity and rapid solidification method, the resistivity of liquid alloy increases with the increase of the temperature and Ni content, and shows the linear and nonlinear change successively; the various tests on melt-spun Al-Ni alloy show that the alloys, which contained amorphous structure and treated with higher melt temperature, have a favorable corrosion resistance and hardness, which can reflect and verify the liquid feature from rapidly solidified alloy and amorphous structure. These results indicate that the melt structure becomes homogeneous and disordered with rising temperature, and temperature-induced liquid-liquid structure change occurs at 850-950 degrees C. Based on these results explored the melt structure from different aspects, we describe this melt structure and discuss shallowly the relationship between the melt and amorphous structure.
