ABSTRACT |
The flexural strength distribution of alumina ceramics was observed using ball-on-3 ball test after thermal shock into the distilled water of 25$^{circ}C$ Crack distribution was also observed by dye-penetration after thermal shock test. Fracture probability of alumina ceramics by ball-on-3 ball test was studied and compared with that by 3-point bending test. The crack distance from the center of thespecimen showed the stronger effect on the flexural strength by ball-on-3 ball test than the crack density |
