Alumina dispersion strengthened copper(ADSC) alloy was produced by internal oxidation.The hardness,ultimate tensile strength and electrical conductivity measure
The strength of the deformation-processed Cu-Fe in-situ composite was conducted by material test system(MTS). The results show that the strength increases with
Perovskite-type SrTiO3 powders were prepared by using strontium acetate, tetrabutyl titanate and sodium hydroxide via direct hydrolysis-precipitation process. A
