Abstract

The article discusses the production of large-diameter «ring» capsules with a diameter-to-height ratio of more than 8 and massive large-diameter capsules with a diameter of up to 1000 mm for subsequent production of disk blanks by hot isostatic pressing. The features of filling the capsules with granules in a horizontal position are considered. The shape change of compact blanks after hot isostatic pressing is analyzed and shrinkage coefficients are calculated. The factors that affect the shape change of compact disk blanks and the shrinkage coefficients are examined.
