The State of Art on Research and Application of Dental Alloy Materials;

The combinatorial method has been widely used in various areas related with alloy materials for their phase-diagram,mechanical properties,anti-corrosion properties,and so on,and shows obviously its advantage in fast discovery and optimization of new kinds of alloy,with the help of the successful development and applications of nano-indentation,microstructure analysis and composition ana.

The article introduces several element analysis methods including graphite stove atomic absorption spectrometry,which is used to analyze alloy material,as well as their application circumstances.

A Preliminary Study of Teaching Reform of Metal Material of Power Plant;

Two kinds of specimens made of a kind of TaW alloy material with high strength and high melting point about 3 000 ℃ are processed by a traditional EDM(Electrical Discharge Machining) and a powder mixed EDM separately,and its surface characteristics are tested.

According to the experimental data of the high frequency electrical parameter of the communication product shield unit,the trace metal element influence on the electromagnetic shielding of aluminum alloy material is analyzed in this paper.
