Carbon-carbon composites increasingly are being used for plasma-facing component (PFC) applications in magnetic-confinement plasma-fusion devices. They offer substantial advantages such as enhanced physical and mechanical properties and superior ther

The effect of composition and porosity on the strength and toughness of a binary oxide, HfTiO4, was investigated. This material has several interesting characteristics: (a) a near-zero thermal expansivity (in polycrystalline form) arising from a nega

Boron carbide, in nuclear reactor neutron absorber applications, generates large quantities of helium, some of which is trapped in small bubbles within the grains. Transmission electron microscopy was used to examine the size distribution, shape, and

Young's modulus at room temperature and the fracture surface energy, up to 1200°C, were determined for boron carbide specimens with 0 to 15% porosity. Sonic modulus measurements indicated that the Young's modulus decreased as porosity increased in a

The system HfO/sub 2/-TiO/sub 2/ was investigated in the 0 to 60 mol percent TiO/sub 2/ region using x-ray diffraction analysis, differential thermal analysis, melting-point studies, and dilatometry. For samples quenched from 1500 and 1250/sup 0/C, s

Thermal expansion is determined by measuring interferometrically the relative displacement of two fibers attached to specimens. Coherent monochromatic light from a laser incident upon the two adjacent fibers produces a Fraunhofer fringe pattern. Rela

The leading LMFBR control rod material, B/sub 4/C, was examined by SEM, TEM, and X-ray diffraction after irradiation up to 80 x 10/sup 20/ captures/cm/sup 3/ between 500/sup 0/ and 920/sup 0/C. Bulk swelling was found to be the result of elastic and

Grain growth was studied at 1300°, 1400°, and 1500°C in nearly theoretically dense (0.1 to 0.8% porosity) hot-pressed magnesium oxide (99.99+%) and magnesiowustite (0.10 and 0.48 wt% Fe2O3). Small amounts of porosity had large effects on the kinet
