  • Method, device and powder for the additive manufacturing of a component with oxide dispersion strengthening and corresponding component
    Patent number: 11654485
    Abstract: A method for the additive manufacturing of a component includes providing a powdered base material for a component, in particular a component for the hot gas path of a gas turbine, building up the component layer by layer on a building platform by fusing individual layers of the base material, and introducing an oxide dispersion strengthening into a region of the component to be additively manufactured by an oxidic additive, wherein the region is usually exposed to high thermomechanical loading during operation of the component.
    Type: Grant
    Filed: April 17, 2019
    Date of Patent: May 23, 2023

  • Gas-phase polymerisation of conjugated dienes in the presence of rare earth allyl compounds
    Patent number: 5958820
    Abstract: A process for polymerizing a gaseous conjugated diene by bringing it in contact with a catalyst consisting of a rare earth allyl compound, an organic aluminum compound, an inorganic support and optionally, the same or a different conjugated diene. The resulting polymers possess elevated proportions of cis-1,4 units.
