Preparation and Property Study of CuCr Alloy Based on SHS

Abstract:

Copper oxide and pure chromium being as raw materials,CuCr contact composites can be fabricated through the self-propagating high-temperature synthsis technology,then the microstructure of the samples was observed under a metallographic microscope and the effects of different chromium content on hardness and electric conductivity of CuCr alloys were studied.The experiment's results showed that the SHS reaction of CuO-Cr-Al system could react drastcally,give off a lot of heat and CuCr alloy could be obtained simply as well as with low cost. With the increase of the chromium content, the hardness of the CuCr alloy was elevated, but the electric conductivity was decreased.
