Effect of Al sub 2 O sub 3 Particles on the Growth Kinetics of Molybdenum Grains in Liquid Nickel

Grain growth inhibition by inert third phase particles during liquid phase sintering has been investigated in Mo--Ni alloys (96Mo--4Ni, 95Mo--5Ni) containing Al sub 2 O sub 3 particles sintered at 1460 deg C. The grain growth is inhibited slightly by the Al sub 2 O sub 3 particles, and this result i...

Summary:Grain growth inhibition by inert third phase particles during liquid phase sintering has been investigated in Mo--Ni alloys (96Mo--4Ni, 95Mo--5Ni) containing Al sub 2 O sub 3 particles sintered at 1460 deg C. The grain growth is inhibited slightly by the Al sub 2 O sub 3 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 Mo grain and the Al sub 2 O sub 3 particle. The result is compared to those obtained earlier with specimens containing highly soluble third phase particles. 14 ref.--AA
