Abstract
The empirical rate equations of solid state reactions such as recovery of deformed metals, clustering, and transient creep are all of the same type, referred to here as recovery kinetics. For two systems, transient creep in fcc metal crystals and the first stage of tempering of Fe–C and Fe–Ni–C martensite, the rate equations were analysed 30 years ago using the increment technique. These results can be used to deduce the common physical principles which govern the mechanisms operating in the various systems. From this basis, it can be concluded that the densification kinetics in the intermediate stage sintering of certain ceramic green pellets is also a type of recovery kinetics. Initial experimental results are shown to support this conclusion.MST/1048
