Abstract

Grain growth inhibition by inert third phase particles during liquid phase sintering has been investigated in Mo-Ni alloys containing Al2O3 particles sintered at 1460° C. The grain growth is inhibited slightly by the Al2O3 particles, and this result is explained in terms of the shielding of material precipitation at the contact area and of the suppression of material precipitation around the contact area, which is determined by the dihedral angle between the molybdenum grain and the Al2O3 particle. The result is compared to those obtained earlier with specimens containing highly soluble third phase particles.
