Electrical resistance and structure of short-range order alloys based on nickel at high temperatures

The research is considered with Ni-Cr and Ni-Cr(20)-C, high-temperature alloys. The purpose of the work is to reveal a character of the interaction for low concentrations of alloying elements with 3d-transition metals. In the result of the study anomalies on the isotherms of the specific electrical resistance and a number of structural characteristics, as well as the hysteresison separate polytherms have been discovered. The experimental results have shown a complicated microheterogeneous structure of diluted solutions of the systems studied about the melting temperature point. It has been determined, that at heating of commercial and a number of model alloys above a completely definite temperature for every alloy a structure of a final product is improved, service properties are increased. The results of the experimental study of the specific electrical resistance and structure of commercial alloys have been used to develop a new melting processAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
