Abstract:

THE EFFECT OF ALUMINA PARTICLES ON THE NUCLEATION AND GROWTH OF CRACKS THROUGH SILVER CHLORIDE MATRIX HAS BEEN INVESTIGATED. IT HAS BEEN FOUND POSSIBLE TO PROMOTE FIBROUS CRACKING IN DISPERSION-STRENGTHENED SILVER CHLORIDE UNDER NOTCHUMPACT CONDITIONS AT TEMPERATURES AT WHICH SILVER CHLORIDE ALONE CLEAVES BRITTLELY. THE MODIFICATION OF FRACTURE BEHAVIOR IS THOUGHT TO BE DUE TO THE RELAXATION OF HYDROSTATIC STRESS BENEATH A NOTCH BY THE NUCLEATION OF CAVITIES NEAR ALUMINA PARTICLES
