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...

Divecha, Amarnath P., Lare, Paul J., Hahn, Henry

Fabrication and Testing of Sapphire Filament Reinforced Superplastic Ni-Cr-Fe Alloy Composites. (2002)

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...

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...

Research and Exploratory Development on the Fabrication and Characterization of Fiber Reinforced Light Metal Alloy Composites. (1998)

Lare,P. J., Hermann,Robert A., Hahn,Henry

Discontinuous beta-SiC whiskers and chopped C filaments were used as a reinforcement for strengthening 7178 and 2024 Al alloys. The C fibers were coated with Cu to improve wetting. Tensile properties...

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...
