Latest Patents

Qing Ma holds a patent for a method titled "High power x-ray welding of metal-matrix composites." This invention provides a novel technique for joining MMCs using high power x-rays as a volumetric heat source. The method involves directing x-rays to the weld line between two adjacent MMC materials, creating an irradiated region or melt zone. The x-rays utilized have a power density greater than about 10⁴ watts/cm², which is essential for achieving the necessary heat to join the materials effectively. Importantly, the reinforcing material within the MMCs remains uniformly distributed in the melt zone, ensuring that the strength of the composites is not compromised.
