Investigation of Fiber-Reinforced Metal Matrix Composites Using a High Energy-Rate Forming Method.
Abstract
The objective of this program was to investigate fiber-reinforced metal matrix composites by a High Energy-Rate Forming method (HERF). Phase 1 consisted of constituent characterization, preparation of compatibility specimens and tensile screening tests on seven composite systems: SiC Whisker/Ti-6Al-4V; SiC Whisker/Ti; Al2O3 Whisker/Ti-6Al-4V; Al2O3 Whisker/Ti; Al2O3 Whisker/Ni; Al2O3 Whisker/Fe-Cr-Al; and SiC Filament/Ti-6Al-4V. Phase 2 consisted of process development and optimization, followed by characterization of one of two systems selected during Phase 1 (SiC filament in Ti-6Al-4V). The filament system provided improved high temperature stress-rupture properties. Rule-of-mixtures tensile strengths were obtained with 28 vol % specimens. The Ni-Al2O3 whisker system could not be fabricated with powder metallurgy techniques due to fiber breakage.
