Studies of the Reinforcement of Metals with Ultra High Strength Fibers (Whiskers).
Abstract
Ide ifiers: Whiskers, Composite materials. The feasibility of reinforcing Nichrome or other high temperature alloys with high strength Al2O3 fibers (whiskers) was examined experimentally. The primary problems were the development of a strong bond between the metal matrix and the fibrous non-metallic reinforcing phases, and the development of a method to produce dense composites useful ultimately as structural shapes in which the reinforcing fibers are oriented with respect to stress. An extrusion process for producing such composites with oriented structures was developed. The process can be utilized in commercial practice at an anticipated reasonable cost for production of wire, sheet, bar, and uniform cross section of rod stock. Heat treatment in air of a composite containing excess Cr metal resulted in the most significant findings with respect to bond development and a survey. An Al2O3-Cr2O3 Nichrome bond producing useful strength was formed at least in part. (Author)
