To understand the effect of alloy stoichiometry on the microstructural development and mechanical behavior of γ-TiAl- based materials, it is necessary to have a determination of the phase relationships for the TiAl ...
Small amount(0.5-0.8at.%) of niobium addition to the multicomponent alloys based on Fe3Al(Fe-28Al-5Cr-0.5Mo-0.05Zr-0.05B-0.1Ce) results in the microstructural refinement and the increase in the yield strength at tempe...
Preparation of P2W15M15Mo2NbO627- was reported in the paper. It was characterized by elementry analysis, IR,UV, polarography, 183 W-NMR and XPD spectra. All results showed the structure of the heteropoly anion was the...
The experimental results of niobium enrichment in laboratory and in blast furnace in Baotou Iron and Steel Corporation were reported.The effects of temperature,constituents of slag and silicon content in hot metal on ...
