STUDY OF THE EFFECT OF TECHNOLOGICAL MODES FOR PRODUCTION OF DISPERSION-STRENGTHENED COPPER BOND FOR DIAMOND TOOLS ON ITS MECHANICAL PROPERTIES Smirnov V.M., Ph.D. (Physics and Mathematics), Associate Professor, e-mail: vms53@inbox.ru Balmin A.E., Post-graduate Student, e-mail: balmin98@mail.ru I.N. Ulianov Chuvash State University, 15 Moskovsky Prospekt, Cheboksary, 428015, Russian Federation Abstract The paper presents the results of a study of the influence of the processing time of the Cu-0.3Al1Ti-0.3C powder mixture in an attritor on the average granule size and sintering mode on the mechanical properties of the dispersion-strengthened Cu-Ti-Al-C-O-Sn copper binder. It is shown that the minimum average size of Cu-0.3Al-1Ti-0.3C granules and the maximum hardness of the Cu-Ti-Al-C-O-Sn binder material is achieved at a time of processing granules in the attritor equal to 120 min. The influence of temperature and sintering time on the hardness and ultimate compressive strength of the Cu-Ti-Al-C-O-Sn binder material made using mechanically alloyed Cu-0.3Al-1Ti0.3C granules with a treatment time in the attritor of 120 min is studied. It is shown that the ultimate compressive strength of the investigated binder material increases with increasing sintering temperature and especially strongly, more than 2 times, at a sintering temperature of 800 °C. Keywords Dispersion-strengthened copper bond, mechanically alloyed granules, tin powder, diamond tools, hardness, compressive strength.
