摘　　要：研究了烧结温度和保温时间对Cu-1.5wt%Cr复合材料相对密度、电导率、硬度和抗弯强度的影响。结果表明,提高烧结温度和延长保温时间可提高Cu-1.5wt%Cr复合材料的相对密度(可达到96%),降低电阻率,改善导电性,但同时会降低其硬度和抗弯强度。对上述性能变化的原因进行了分析。The effect of temperature and duration of sintering on the relative density, conductivity, hardness and bending strength of Cu-15wt% Cr composite was studied. The results show that for Cu-15 wt% Cr composite, the relative density will become higher（amounting to 90% ） , the resistivity be decreased and the conductivity become better, however,the hardness and bending strength will be decreased with both the increase of sintering temperature and the prolongation of duration. The causes resuhing in the above variation in properties were analyzed.
