抄録

A DC pulse resistance-sintering process is introduced to reduce the long processing time in the net shape sintering process of parts including intermetallic compounds by a hot-pressing (HP) process with chemical reaction between copper and aluminum powders and titanium and aluminum powders. By the DC pulse resistance-sintering mixed powder materials are sintered directly by a phenomenon of microscopic electric discharge between the particles using a DC pulse generator under a punch pressure in a graphite die. The powder mixtures of Cu-33 at % Al and Ti-50 at % Al were milled by a mechanical alloying (MA) process. The MA powder mixtures were sintered using the DC pulse resistance-sintering process. It has been confirmed that the mechanical properties obtained in a short processing time of only about 10 min by the resistance-sintering processes are as same as those in a long processing time of 2-3 hours by the HP process.
