Twenty-one elements were screened for solubility in selected titanium-carbide compositions at 1600°C. Tin, lead, and aluminum were found to dissolve to an appreciable extent only in carbide compositions very near the titanium-titanium carbide phase

The thermal diffusivity of mullite-ZrO{sub 2}-SiC{sub w} materials was determined from 25 to 1,000 C for composites in which the ZrO{sub 2} had different amounts of monoclinic and tetragonal phase, and varying SiC{sub w} content. At 25 C the thermal

The oxidation of SiC whiskers, contained in alkoxide-derived mullite-based matrices and exposed in air at 1000--1350 C for up to 1000 h, has been studied by analytical TEM, high-resolution SEM, and XRD. Silicon carbide whiskers were effectively prote

The McLachlan equation, which incorporates both effective medium models and percolation, was used to predict the volume fraction-conductivity relationships of insulator-conductor composites, and results were compared with experimental data. Two compo

Nanophase-structured composites were fabricated by heat treating hot-pressed 2H-wurtzite SiC-AlN solid-solution specimens of 25, 50, and 75 mol% AlN within the spinodal decomposition zone. Heat-treatment conditions were 1750°C for 150 h, in flowing

A composite consisting of 30 wt% SiC whiskers and a mullite-based matrix (mullite-32.4 wt% ZrO 2 -2.2 wt% MgO) was isothermally exposed in air at 1000°-1350°C, for up to 1000 h. Microstructural evolution in the oxidized samples was investigated usi

The electrical behavior of hot-pressed mullite composites reinforced with 10, 20, and 30% SiC whiskers (SiCw) was evaluated in the frequency range 100 Hz–10 MHz and compared with 2 GHz data as well as dc resistivity measurements. It is found that t

A series of SiC-AlN compositions of 0, 10, 25, 50, 75, 90, and 100 mol% AlN were hot pressed at 2100°C for a 1 h soak at a pressure of 35 MPa under vacuum. 2H-wurtzite SiC-AlN solid-solution structures were formed for compositions with 25-100 mol% A
