The purpose of this work is a study of the influence of the energy consumptions in electric-discharge sintering on the sintering temperature, phase composition, porosity, hardness, and specific electric resistance of a copper-tin-abrasive sintered composite. The investigations were made on specimens in the form of 50 x 6 x 4 mm parallelepipeds sintered from an electrocorundum composite. The structural transformations were studied by x-ray diffraction on a DRON-2.0 instrument in CuK/sub gamma/-radiation and metallographic analysis. It is established that by changing the specific energy consumption, parts with different structures and properties are obtained from this composite by electric discharge sintering.
