  • METHOD FOR CARBIDE DISPERSION STRENGTHENED HIGH PERFORMANCE METALLIC MATERIALS
    Publication number: 20230287539
    Abstract: A method of preparing a mixture of a metal or metal alloy and (NbxTi1-x)C (where 0<x?1) in which (NbxTi1-x)C in particulate form (either with or without metal powder) is formed into a preform and then if necessary added to the metal. The resulting (NbxTi1-x)C/metal mixture can then be heated to a temperature below the melting point of the (NbxTi1-x)C and optionally dispersed in liquid metal and/or casted and cooled to produce a solid product with improved physical properties.

  • Method of refining metal alloys
    Patent number: 10329651
    Abstract: Method of refining metal alloys A method of refining the grain size of (i) an alloy comprising aluminum and at least 3% w/w silicon or (ii) an alloy comprising magnesium, comprises the steps of (a) adding sufficient niobium and boron to the alloy in order to form niobium diboride or Al3Nb or both, or (b) adding niobium diboride to the alloy, or (c) adding Al3Nb to the alloy, or (d) any combination thereof.
    Type: Grant
    Filed: February 10, 2012
    Date of Patent: June 25, 2019
    Assignee: Brunel University London
    Inventors: Hari Babu Nadendla, Magdalena Nowak
  • AL-NB-B MASTER ALLOY FOR GRAIN REFINING
    Publication number: 20150218673
    Abstract: A method of producing a master alloy for refining the grain size of a bulk alloy comprises the step of providing an Al—B alloy and adding Nb in elemental form to form an Al—Nb—B master alloy. The Al—B alloy may be prepared by providing an Al—B alloy with a higher boron content than is required and diluting it with elemental aluminium.
