  • Extreme creep resistant nano-crystalline metallic materials
    Patent number: 10766071
    Abstract: Novel metallic systems and methods for their fabrication provide an extreme creep-resistant nano-crystalline metallic material. The material comprises a matrix formed of a solvent metal with crystalline grains having diameters of no more than about 500 nm, and a plurality of dispersed metallic particles formed on the basis of a solute metal in the solvent metal matrix and having diameters of no more than about 200 nm. The particle density along the grain boundary of the matrix is as high as about 2 nm2 of grain boundary area per particle so as to substantially block grain boundary motion and rotation and limit creep at temperatures above 35% of the melting point of the material.
    Type: Grant
    Filed: February 14, 2018
    Date of Patent: September 8, 2020
    Assignee: The United States of America as represented by the Secretary of the Army
    Inventors: Laszlo J. Kecskes, Kristopher A. Darling, Rajiv S. Mishra, Yuri Mishin, Kiran N. Solanki, Mansa Rajagopalan
