Abstract:
With the continuous development of modern technology, the intersection between different disciplines and the application of outfield technology in metallurgical process, a new interdisciplinary subject, special metallurgy, was formed. Self-propagating high-temperature synthesis (SHS)metallurgy, as a branch of special metallurgy, is one of the most important research field. By the immediate release of chemical reaction heat of the reaction system itself , SHS-Metallurgy method can quickly form an ultra high transient temperature field, thus realizing fast and efficient preparation of the high melting point metals and compounds. This paper systematically discusses the production and present application situation of the high melting point ultrafine metal powder, ultra-fine boride ceramic powder and the latest research results on SHS-Metallurgy in the preparation of the high melting point ultrafine metal powder; the production and present application situation of titanium-based alloys and copper-chromium immiscible alloy, its preparation disadvantages such as high cost, long and complex process, and the latest research results on aluminothermic reduction-multistage depth reduction in the direct preparation of titanium-based alloys and copper-chromium immiscible alloy.
