金属熔体扩散的研究进展
摘要
Diffusion in liquid metals is significant in materials engineering as a key parameters for materials design, and also a long standing topic in the study of transport properties in condensed matter physics. Due to experimental difficulties, few great progresses have been reported in the past several decades. In China, both experimental and theoretical researches are very rare. By introducing the latest diffusion measuring techniques including the in-situ X-ray radiography and neutron scattering methods, we systematically describes the current melt diffusion measurement techniques, and the experimental results obtained on the ground and under the microgravity conditions in space. The theoretical models concerning the diffusion mechanisms are also explained briefly. Finally, we point out the problems and prospective future in the field of metallic liquid diffusion.
