摘　　要：通过压制压力、烧结温度和烧结时间对WC／Cu压坯组织和性能的影响，研究了粉末冶金颗粒增强复合材料的烧结特点，确认了WC颗粒对烧结的阻碍作用，认为WC／Cu压块不能通过简单烧结来达到致密化。The effects of pressure, sintering temperature and sintering time on the microstructures and properties of WC/Cu compacts are studied. The characteristics of the particle reinforced for com-posites are also investigated. It is confirmed that WC particles have obstructive effects on sintering and the WC/Cu compacts can not be densified by common sintering. The reliable processing parameters for the preparation of WC/Cu composites are given in this paper
