Self-diffusion coefficients obtained in model sintering experiments

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

Conclusions

A description is given of the correct procedure for processing results of model sintering experiments for the purpose of finding coefficients of self-diffusion. It is shown that the large quantity of published data on X vs t relationships has been processed without taking into account the strong influence of the initial stage of rapid contact growth, which is followed by a stage of slow growth, on the value of D determined from the X vs t relationship.
