  • Solidification refinement and general phase transformation control through application of in situ gas jet impingement in metal additive manufacturing
    Patent number: 11752547
    Abstract: Provided are a jet device and systems and methods using the jet device for manufacturing objects by additive manufacturing, especially titanium and titanium alloy objects, wherein the jet device directs a cooling gas across a liquid molten pool, or to impinge on the liquid molten pool, or to impinge upon a solidified material adjacent to a liquid-solid boundary of the liquid molten pool, or to impinge on an as-solidified material, or any combination thereof, during the additive manufacturing process. The application of the cooling gas can result in an additively manufactured metal product having refined grain structure with a high proportion of the grains being approximately equiaxed, and can yield an additively manufactured product exhibiting improvements in strength, fatigue resistance, and durability.
    Type: Grant
    Filed: June 29, 2018
    Date of Patent: September 12, 2023
    Assignee: Norsk Titanium AS
    Inventors: Martin Borlaug Mathisen, Hilde Løken Larsen
  • Method and arrangement for building metallic objects by solid freeform fabrication
    Patent number: 11213920
    Abstract: Provided are a systems and methods for manufacturing objects by solid freeform fabrication, especially titanium and titanium alloy objects, wherein the deposition rate is increased by using two separate heat sources, one heat source for heating the deposition area on the base material and one heat source for heating and melting a metallic material, such as a metal wire or a powdered metallic material.
