improves with increasing Cr content. It is indicated that Cr addition can benefit pesting control in MoSi2. Key words: molybdenum silicides; pesting; oxidation; alloying ... stabilizer) added alloys with pure C40 structure did[12]. However, a study on the effect of Al concentration on pesting in MoSi2 showed that even as low as 5% (molar fraction) Al, i.e., single-phase......
; Abstract: Uniform nanoparticles of molybdenum nitride were synthesized by temperature-programmed reaction(TPR...). Results show that the material consists of a pure phase of γ-Mo2N nanoparticles with average diameter of about 16 nm. The material presents a specific capacitance of 172 F/g in 1 mol/L H2SO4......
Elastic-plastic analytical solution for centric crack loaded by two pairs of point shear forces in finite plate ZHOU Xiao-ping(周小平)1, LING Tong-hua(凌同华)2 1. School of Civil Engineering...: The near crack line analysis method was used to investigate a centric crack loaded by two pairs of point shear forces in a finite plate, and the analytical solution was obtained. The solution......
, TIAN Jia-min (State Key Laboratory of Powder Metallurgy, Central South University, Changsha 410083, China) Abstract: The pure molybdenum and MT alloys were prepared by powder metallurgy process. The oxidation behavior and ablation behavior in oxyacetylene of pure molybdenum and MT alloys at 1200℃ were studied. The results indicate that the oxidation of pure molybdenum arises from defects......
