    Thermodynamics of sintering - ScienceDirect

    The energy changes in sintering are usually small, so the rate of change during sintering is slow. In the case of the 26 μm bronze powder shown in Fig. 1.1, which has a solid–vapor surface energy of 1.7 J/m 2, the energy per unit mass stored as excess surface area is about 50 J/kg. But not all of this energy can be consumed during sintering ...

In a compact that contains only iron powder particles, the solid state sintering process would generate some shrinkage of the compact as the sintering necks grow. However, a common practice with ferrous PM materials is to make an addition of fine copper powder to create a transient liquid phase during sintering.
