Glass formation adjacent to the intermetallic compounds in Cu-Zr binary systemYinxiao Wang,Jiahao Yao,Yi LiShenyang National Laboratory for Materials Science, Institute of Metal research, Chinese... kinetics, here we present our findings that bulk metallic glasses are readily formed near intermetallic compounds, far away from the traditional region of glass forming near eutectics. While......
A Study of the Specific Heats of the Compounds in the Sm2O3-BaO-CuO System乔芝郁,袁文霞,邢献然,成向荣摘 要:<正> By means of X-ray diffraction and adiabatic scanning calorimeter,the specific heatsof five compounds in the Sm2O3-BaO--CuO system,such as Sm2BaO4,Sm2CuO4,BaCuO4,Sm2BaCuO5,SmBa2Cu3O7-x,from -150℃ to 800℃ have been measured.It is found that the specific......
Prediction of the Gibbs Free Energies of Formation of Intermediate Compounds in a Binary SystemLi Ruiqing General Research Institute for Non-ferrous Metals,Beijing摘 要:<正> A method for predicting the Gibbs free energies of intermediate compounds in a binary system has been presented,based upon the regulations of the Gibbs free energies of formation......
. As the brazed joints by the Al-based filler are known to be very brittle with low fatigue resistance and impact strength[6], temperature much more than 1 100 °C, those two groups of filler alloys..., the dissimilar joints between Ti and stainless steel were dominated by the Ti-based intermetallic compounds (IMCs), e.g. (Ti, Zr)2(Fe, Ni), TiFe, TiCu, and Ti2(Fe, Ni), due to a significant dissolution......
