  • Magnesium grain refining using vanadium
    Patent number: 8784579
    Abstract: A process of grain refining magnesium metal or magnesium based alloy including the step of a) providing a melt of the magnesium metal or magnesium based alloy, said melt including a grain refining agent in an amount effective to induce grain refinement of said magnesium or magnesium based alloy upon solidification, wherein the grain refining agent is vanadium metal, where said grain refinement comprises a reduction in average grain size of at least 50% (percent) as compared with the average grain size without addition of said grain refining agent.
    Type: Grant
    Filed: April 20, 2009
    Date of Patent: July 22, 2014
    Inventor: Joka Buha
  • Method of heat treating magnesium alloys
    Patent number: 8414717
    Abstract: A method for the low temperature heat treatment of an age-hardenable magnesium based alloy, including following steps: (a) providing a solution heat-treated and quenched age-hardenable magnesium based alloy; and (b) subjecting said alloy to low temperature ageing below 100°C. for a period of time sufficient to develop an enhanced ageing response.
