Conclusions

  1. 1.

    Universal gauges have been developed for the continuous, automatic monitoring and recording of the shrinkage of metal powder parts during sintering. The gauges can be used in conjunction with furnaces of all types, at temperatures up to 3000°C, with an error of not more than 2%.

     
  2. 2.

    Automatic shrinkage determination makes it possible to conduct thorough investigations into the sintering kinetics of various materials with the aim of establishing the laws governing sintering processes.

     
  3. 3.

    Using data yielded by automatic shrinkage measurements, it is possible to determine the density of metal powder parts during sintering when the initial compact density γ0 and an experimental coefficient K are known.
