Research on Whisker-Reinforce Metal Composites. (2005)
Lare,Paul J., Ordway,Fred, Hahn,Henry
The thermal stability of Al2O3 whiskers in a 2.5% Si-Al alloy matrix was investigated by heating composite samples to 370C in air for exposure times up to 7500 hours. No significant deterioration in...
Research on Whisker-Reinforced Metal Composites. (2005)
Lare, Paul J., Ordway, Fred, Hahn, Henry
Techniques for processing as-grown whisker mats of Al2O3 and beta-SiC were improved. Nonwhisker debris could not be eliminated from the Al2O3 whiskers, but was significantly reduced compared to...
Improvement of the Transverse Strength of Continuous Filament Reinforced Light Alloys. (2002)
Swindells,Frank E., Lare,Paul J.
This research was directed toward improvement in the transverse properties of light alloys reinforced with Borsic fibers. Encapsulation of approximately 10% of silicon carbide whiskers, aligned...
Lare,Paul J., Ordway,Fred, Hahn,Henry
Experimental efforts to fabricate composite samples of a Ni-Cr-Fe alloy reinforced with Al2O3 filaments are described. Sapphire filament/polystyrene layup sheets were sandwiched between sheets of...
Research and Development of Discontinuous Fiber Reinforced Light Alloy. (1998)
Hermann,Robert A., Lare,Paul J., Ordway,Fred, Hahn,Henry
Two approaches to the preparation of titanium alloy composites reinforced with silicon carbide fibers without objectionable fiber-matrix reaction were studied: (1) interposing a protective coating of...
Silicon Carbide Whisker-Metal Matrix Composites. (1998)
Ordway,Fred, Lare,Paul J., Hermann,Robert A.
Aluminum alloy composites reinforced with silicon carbide whiskers were prepared by liquid-phase hot pressing of aligned whisker-powder bodies. Biaxial (x-y) alignment was obtained by filtering a...
Fabrication and Testing of Sapphire-Reinforced Superplastic Ni-Cr-Fe Alloy Composites. (1998)
Lare,Paul J., Ordway,Fred, Hahn,Henry
Progress toward the fabrication of composites of Ni-Cr-Fe alloy reinforced with Al2O3 filaments is described The sapphire filament material was found to vary in strength with the density and...
Development of Whisker-Reinforced Light Alloys. (1998)
Hermann, Robert A., Lare, Paul J., Ordway, Fred, Hahn, Henry
The objectives of the program were to fabricate and characterize magnesium alloy/alpha-SiC whisker composites and investigate methods for producing titanium/SiC whisker composites. Magnesium alloy...
