Latest Patents

One of Tzy C Peng's latest patents is for an advanced titanium composite. This titanium alloy features greatly increased specific strength and enhanced thermostability. The alloy consists of a titanium matrix in which fibrous dispersoids are formed in situ. These dispersoids are rod and/or plate-shaped, with a diameter or depth of about 0.1-0.5 microns and an aspect ratio of about 5-10. A typical alloy has the composition A-X, where A is titanium or a titanium alloy, and X is boron, carbon, nitrogen, or mixtures thereof, including silicon.

Another significant patent involves a laser melt spin atomized metal powder production process. This method utilizes a spinning metal source and a laser beam to melt the surface layer of the source and atomize it. The laser beam is directed at a glancing angle along the surface of the spinning metal source, which spins at a high speed of 10,000-30,000 revolutions per minute. The atomized metal is rapidly solidified in an inert gas atmosphere, achieving very high cooling rates up to 10^6 degrees Celsius per second. This process results in very small and uniformly distributed particles of rapidly solidified metal, typically having a narrow particle size distribution from about 50-150 microns, with a high percentage of particles below 100 microns.
