Conclusions

  1. 1.

    The most objective data upon the size of particles in dispersion-strengthened alloys are provided by electron diffraction microscopy.

  2. 2.

    The method of extraction and subsequent electron microscopical examination of particles ensures high reliability in determinations of particle size parameters and enables analysis to be carried out at any stage of alloy preparation.

  3. 3.

    The x-ray method of determination of mean particle sizes gives reliable results when few inclusions more than 1000 Å in size are present. The method can also be recommended for the evaluation of relative changes in the size of strengthening phase particles under the action of various factors. In investigations of this type, the presence of a large number of coarse particles is not an obstacle.
