A model has been developed to simulate the heat transfer behavior during spark plasma sintering (SPS) process and by using the pure spherical copper particles as an example, the temperature distribution and the neck size evolution of the powder particles have been studied.
以球形铜粉为研究对象, 对颗粒内部温度分布和颈部尺寸变化进行了模拟计算和分析,模拟结果表明:SPS过程中颗粒内部的温度分布极不均匀,烧结颈部的长大速率在烧结过程中并不一致。
