A Novel Criterion of Mixing Time in Gas-Stirred Ladle SystemsJun Zhang22. School of Metallurgy and Resource, Anhui University of Technology摘 要:A novel criterion of mixing time in gas-stirred ladle systems was proposed in this paper. The essential difference between the previous criterion and the present one is that the former is based......

, 10, 15, 20) alloys with nanocrystalline and amorphous structures were prepared by melt spinning technology. The structures of the as-cast and spun alloys were characterized by X-ray diffraction (XRD... facilitates the glass forming of the alloys. Both the Nd-addition and the melt spinning significantly improve the gaseous and electrochemical hydrogen storage kinetics of the alloys. The addition of Nd......
words: Cu-Cr alloy; liquid phase separation; melt spinning; rapid cooling 1 Introduction Cu-Cr alloys containing 20%-50%Cr have been widely investigated because they are the most important... not widely used. In order to obtain refined microstructures, in our prior work[10] we prepared Cu-Cr ribbons containing 3%-25%Cr by melt spinning. It was found that a lot of larger Cr particles were......
