Large products from refractory carbides

Conclusions A technology was developed for making large blanks of zirconium and niobium carbides. The technique includes slip preparation, preforming of the blanks by hot casting or hot extrusion, and hot die casting in vacuum at 2200°C.Using this method articles were made whose density was 96–97% of the theoretical. There were no internal defects according to ultrasonic control checks.Translated from Ogneupory, No. 6, pp. 49–52, June, 1967.
