Rhodes, C G

Microstructures of hot-pressed UC specimens were examined to determine the sintering characteristics relative to temperatures of 518 to 1490 deg C and pressures of 10 to 46 k atmos. Measurements of the volume percent porosity of each sample were made by lineal analysis. The causes of inter-granular microcracks observed in the specimens are discussed. X-ray-diffraction studies of hot-pressed samples indicate that the grains were fragmented into subgrains and the size and perfection of the subgrains varied with the pressing temperature. (B.O.G.)
