Texture and residual strain in SiC/Ti-6-2-4-2 titanium matrix composites

PDF Version Also Available for Download.

Description

Residual strain and texture variations were measured in two Titanium matrix composites reinforced with Silicon Carbide fibers (Ti/SiC) having the same composition but fabricated by dramatically different processing routes. In both specimens the Titanium matrix comprised an {alpha}/{beta} alloy (Ti-6242) containing approximately 35% by volume of continuous SiC fibers. In one case the matrix was produced by a plasma spray (PS) route and the other by a wire drawing (WD) process. The resulting textures in the matrix differ significantly, from approximately random for the PS matrix to 6.25X random in the WD matrix. No significant differences in matrix residual strains ... continued below

Description

Residual strain and texture variations were measured in two Titanium matrix composites reinforced with Silicon Carbide fibers (Ti/SiC) having the same composition but fabricated by dramatically different processing routes. In both specimens the Titanium matrix comprised an {alpha}/{beta} alloy (Ti-6242) containing approximately 35% by volume of continuous SiC fibers. In one case the matrix was produced by a plasma spray (PS) route and the other by a wire drawing (WD) process. The resulting textures in the matrix differ significantly, from approximately random for the PS matrix to 6.25X random in the WD matrix. No significant differences in matrix residual strains between the composites prepared by the two procedures were noted. Plane-specific elastic moduli, measured in load tests on the unreinforced matrices also showed little difference.
