and Cu-Cr are in liquid and solid two-phase regions. However, once the liquid phase separation takes place, the solidification of primary crystals would stop or not occur because the Gibbs free energy... not carry out fully in rapid cooling. The Cr particles, as shown in Fig.6, will be finer. Due to the liquid phase separation, the supersaturation solid solution of Cr in Cu was obtained......
[10,14-15]: (1) where Nn is the quantity of latent heterogeneous nucleation particles in unit volume melt; da is the average atom diameter of nucleation solid phase; XL,eff is the effective alloy concentration[10-16], and its value is always less than 1. XL,eff approaching 1 shows that the composition of solid phase approaches that of the melt. For the binary alloy, XL,eff=XL,A/XS......
Fabrication and electrochemical performance of solid oxide fuel cell components by atmospheric and suspension plasma spray XIA Wei-sheng(夏卫生)1, 2, YANG Yun-zhen(杨云珍)3, ZHANG Hai-ou(张海鸥)2, WANG Gui...; Abstract: The theory of functionally graded material (FGM) was applied in the fabrication process of PEN (Positive- Electrolyte-Negative), the core component of solid......
. The microstructure analysis reveals that a part of Zr solves into the Mo matrix , which enhances the tensile strength of the alloys, while the other part of Zr forms oxide second phase particles. However, over-dose oxide particles would generate negative influence on the property of the alloy. Key words: Mo-Zr alloy; solid solution; second phase particles 钼由于具有熔点高,强度大,硬度高,导电导热性好,热膨胀系数低,耐磨损和抗腐蚀性能强及良好的抗热震性能和耐热......
