Temperature dependence of the grain size of NbC0.80

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Summary

A study was made of the effects of temperature in the range 1600–3300°K on the grain size of the nonstoichiometric niobium carbide NbC0.80. The energy of activation of the grain growth process was found to be 65.5 kcal/mole; this value leads to the conclusion that the grain growth process is controlled by boundary and surface diffusions.
