Metal-metal laminar composites for high temperature applications

From proceedings of the symposium on failure modes in composites; Boston, MA (8 May 1972). A study was conducted of the potential of laminar metal- - metal composites for elevated-temperature use. Most of the composites consisted of multiple layers or laminae of tungsten alternated with laminae of Nichrome V, a ductile, weaker, but oxidation-resistant alloy. Composites with 50 vol % of each phase made from 0.0025-cm, 0.0125-cm, or 0.050-cm laminae, were tested in tension and stress rupture at temperatures of 871 and 1093 deg C and in impact at 23 and 524 deg C. A tension and a short time stress-rutpure test was conducted on specimens of 77 vol.% W--Re- W- C/23 vol.% Inconel Alloy 600 at 1093 deg C. (auth)
