| Abstract: | A comparative study of the resistance of alumina-based ceramic materials with different grain-boundary phases to delayed fracture is described. The tests were conducted by the method of dynamic fatigue in air, water, and a salt solution. It is shown that the ceramics with an alkali-free vitreous phase has a higher resistance to subcritical crack growth than the material with an alkali-containing grain-boundary phase.Translated from Ogneupory i Tekhnicheskaya Keramika, No. 11, pp. 2 – 4, November, 1996. |
