The experimental regularity and the mechanism of affecting the specific saturation magnetization(4πσ)of WC-Co cemented carbides were studied by varying alloy
In this paper the heteropoly complexes K<sub>n</sub>[Ga(H<sub>2</sub>0)MW<sub>11</sub>O<sub>3</sub>9)]·xH<sub>2</sub>0 [M=Cu(Ⅱ), Co(Ⅱ), Cr(Ⅲ),Fe(Ⅲ), Mn(Ⅳ)] have b
An inverted torsion pendulum has been used to study the high temperature internal friction of an Al-0.22wt% Zr alloy.Theexperimental result has shown that the g
