A super-fine compound powder,Ag/SnO2+La2O3+Bi2O3,has been obtained using the chemical coprecipitation method.And a new contact material,Ag/SnO2+La2O3+Bi2O3,was
The microhardness and elastic modules of the materials were measured using the Nano Indenter II, which is a new measuring system for the mechanical properties o
The effect of hydrogen on the microstructures and superplasticity of a Ti3Al-Nb alloy was studied. The results showed that hydrogenation made the volume fractio
