Grain refinement of superalloy K4169 was achieved by adding refiners into the alloy melt and their effects on the mechanical properties were investigated. The t
The superplasticity of coarsed grain AZ31 magnesium alloy was investigated in the temperature range of 623-723 K at strain rates from 10-3 to 10-1 s-1. It is fo
Magnetite was modified by reaction with alkaline solution containing Co2+ and Fe2+ to obtain a cobalt ferrite layer on the surface of particles.The influences o
