抄録

Cu-Ti-B powders prepared by mechanical alloying were compacted and then sintered in a temperature range of 873-1273K. Changes in microstructure and mechanical strength of the sintered comacts with the sintering were investigated. Inter-metallic compound TiB₂ is formed through the sintering. The formation of TiB₂ phase is accelerated with increasing of sintering temperature. When the compact was sin-tered for prolonged time at high temperature, copper-rich grain is formed at contact region between the particles. Result of hardness measurement in the sintered com-pacts exhabits two peaks with sintering time in the temperature range of 873-1073K. The hardness value reachs the first peak in less than about 20ks and the secound peak requires longer sintering time than 70ks. Both peak values of the hardness decrease with the increasing of sintering temperature. It is confirmed by three-points bend-ing test that bonding strength between particles increases with increasing of sintering time.
