Abstract:
Abstract: Diffusion in amorphous alloy melts is an important kinetic parameter to describe the properties in melts. Different from the normal alloy melts, the diffusion behavior of amorphous alloy melts tend to have their own unique properties, such as presented a typical slow diffusivity and a complex temperature dependent. But the researches on atomic diffusion are still at a preliminary stage whether in domestic or international study due to technical and theoretical difficulties. This paper mainly introduced some measurement techniques of the diffusion coefficient, including our self-designed sliding cell method, which combined the merits of the traditional long capillary method and the shear cell method, and ruled out the undesired atomic diffuse occurs in heating process. It’s concerned as an effective way to measure the diffusion coefficients. In addition, based on the diffusion results and models of the amorphous alloy melts, the diffusion research in amorphous alloy melts were summarized and discussed.
