Southwest Technique... words: Mg-Zn-Y-Zr alloy; extrusion ratio; solid state recycling; processing temperature 1 Introduction Magnesium alloys have been widely used in electronic, automotive and aerospace industries, due......
was preserved for ready-use; the concentrations of the manganese and chloride in solid phase were analyzed, and the XRD (X'Pert-Pro, the harrow material is copper) analysis was carried out after the solid... to separate solid and liquid phase. The concentration of manganese in liquid phase was analyzed in order to calculate the solubility of Mn2(OH)3Cl in water. This step was repeated several times to make sure......
, China) Abstract:Strontium doped lanthanum manganite (LSM) powders were synthesized by three different routes: azeotropic distillation, sol-gel and solid state reaction respectively. The LSM samples, made by azeotropic distillation and sol-gel methods were prepared by firing at 1000 ℃ for 6 h, and the LSM sample, made by solid state reaction method was produced by sintering at 1400 ℃ for 18 h......
at these temperatures. In fact, the Co3Ta phase is reported to form a continuous ternary solid solution extending from the Laves_C36_Co3Ta to the Laves_C36_Co2Ti phase [13]. The Co3Ti phase also has... type Co3Ti phase. 3) Isothermal sections in the Co-rich region of the Co-Ti-Ta system at 1 000, 1 100 and 1 200 °C are constructed based on the measurements in this work. The determined solid......
and silicate. The individual fired pellets are hardened by solid phase diffusion and the racemose sinter are consolidated by both solid phase diffusion and liquid phase bonding, the latter is 30% in sinter.
