The effects of different heat-treatment process on Cu-Zn-Cr alloy s hardness are studied.

Cu-Zn-Cr alloy was prepared by Ingot Metallurgy.

The results show that: The first,Cu-Zn-Cr alloy is .

The role of organic additive in electroplating process of amorphous Cr-C alloy were studied.

In order to obtain chromium containing zinc alloy coating with excellent performance,mechanical plating technologies of Zn-Cr and Zn-Al-Cr alloy coatings were developed through varying the kind and amount of activator and promoter on the basis of mechanical plating technologies of Zn and Zn-Al coatings.

Ageing Behavior of Rapidly Solidified Cu-Cr-Sn-Zn Alloy;

A model of the non-linear relationship between parameters of age processes and hardness and conductivity properties of Cu-Cr-Sn-Zn alloy is established by the artificial neural network(ANN).
