STUDIES OF THE REINFORCEMENT OF METALS WITH ULTRA HIGH STRENGTH FIBERS (WHISKERS)

Abstract

In a project dealing with the reinforcement of high-temperature metals with high-strength fibers, the main emphasis was on the refinement of techniques for mixing, extruding and sintering 80/20 Ni-Cr alloy with CaCl2 to produce composites with more reliable and consistent tensile strengths. Marked reinforcement of the alloy occurred with Al2O3 whi kers, uing CaCl2 as a wetting agent. Vacuum treatment of the raw mix did not reduce the variability signific ntly. A double sintering process yielded reliable tensile strength data, bu the parameter which causes variability in softening points was not found. (Author)
