Latest Patents

One of his latest patents is titled "Diffusion bonding of titanium alloys with hydrogen-assisted phase." This invention involves a titanium-base alloy that undergoes an elevated temperature phase transformation, which is diffusion bonded to a second phase at an accelerated rate or reduced temperature. This is achieved by manipulating the phase transformation with an alloying element that can be easily introduced and removed from the titanium piece. The introduction of hydrogen into the titanium alloy reduces the temperature of the phase transformation, allowing for repeated cycling through the phase transformation before or during bonding. This process reduces the flow stress through transformation plasticity.

Another significant patent is "Interstitially protected oxidation resistant carbon-carbon composite." In this invention, carbon fiber bundles in a carbon-carbon composite are protected against oxidation by coating them with a protective layer consisting of an underlayer of boron carbide and an overlayer of silicon carbide. This innovative approach enhances the durability and performance of carbon-carbon composites in various applications.
