Performance of Commercial and Research Grade SiC Whiskers in a Borosilicate Glass Matrix
Autor: Peter D. Shalek, Frank D. Gac, John V. Milewski, John J. Petrovic
Dry blending of the whiskers and glass powder yielded composites of satisfactory, but not optimum, homogeneity. The whiskers inhibited composite densification, but this could be remedied by modifying the hot-pressing conditions. All types of whiskers

Tensile mechanical properties of SiC whiskers
Autor: D. L. Rohr, John V. Milewski, Frank D. Gac, John J. Petrovic
Publikováno v: Journal of Materials Science. 20:1167-1177
An initial evaluation has been made of the tensile mechanical properties of SiC whiskers synthesized by a vapour-liquid-solid process. A micro-tensile tester and associated testing techniques were developed for this purpose. The SiC whiskers exhibit

Growth of beta-silicon carbide whiskers by the VLS process
Autor: John V. Milewski, Frank D. Gac, S. R. Skaggs, John J. Petrovic
Publikováno v: Journal of Materials Science. 20:1160-1166
Beta-silicon carbide whiskers are being grown by a vapour-liquid-solid (VLS) process which produces a very high purity, high strength single crystal fibre about 6μm in diameter and 5–100 mm long. Details of the growth process are given along with
