In Fe-20Cr-4Al-Y alloys with (0.13~0.73) wt% Y,Y-containing phase was observed.Its Y content andcrystal structure were identical with those Of YFe<sub>9</sub> phas
The mechanism of thermal decomposition of rare earth acetate hydrates(Ln(Ac)<sub>3</sub>·nH<sub>2</sub>O,n=5,forLn=La;n=4,for Ln=Pr→Lu,Y,except Pm)has been st
By using surface effects(Auger electron spectroscopy,X-ray photoelectron spectroscopy,polar Kerreffect)and volume effects(magnetization,torque curve)the physical pr
In this study,fluorinating vaporization combined with ETV-ICP-AES technique was used to determineyttrium for which refractory carbide is easily formed.The absol
