Abstract:Through modular pressing and sintering, the Cu-C powder metallurgy samples were made and the process was investigated. The results show that there exist expanding mechanism and shrinking mechanism in sintering process, and whether the sintering body is shrinking or expanding depends on the interacting between the two mechanisms, and the HD sintering model is in keeping with the actual sintering process.

 

Key words: powder metallurgy; sintering mechanism; sintering model; Cu-C material
