Abstract : Studies have continued toward elucidating means whereby high volume percent alpha alumina whiskers loadings can be incorporated into refractory metal matrices to yield high strength composite structures. These studies used titanium and zirconium hydrides as sources of oxide reactive agents and vacuum metallizing of whiskers to promote their liquid metal infiltration. Vacuum metallizing of whiskers with chromium appears promising toward securing nichrome/alumina whisker composites where the whiskers are present in high volume content. (Author)
