  • Magnesium alloys for hydrogen storage
    Patent number: 9234264
    Abstract: A method of producing a hydrogen storage material including the steps of: forming a magnesium-nickel melt having up to 50 wt % nickel; adding up to 2 wt % of a refining element to the melt under a non-oxidizing atmosphere, the refining element having an atomic radius within the range of 1-1.65 times the atomic radius of magnesium, such as at least one element selected from the group consisting of Zr, Na, K, Ba, Ca, Sr, La, Y, Yb, Rb and Cs; and solidifying the melt to produce the hydrogen storage material.
    Type: Grant

  • Aluminium casting alloy
    Patent number: 8097101
    Abstract: A method of forming a hypoeutectic aluminium silicon alloy including the steps of: forming an aluminium melt including greater than zero and less than about 12 wt % silicon, adding 20-3000 ppm of a eutectic modifying element selected from the group consisting of strontium, sodium, antimony, barium, calcium, yttrium, lithium, potassium, ytterbium, europium and mischmetal; and either adding nucleant particles and/or causing nucleant particles to be formed in the melt, the nucleant particles being selected from the group of TiSix, MnCx, AlP, AlBx and CrBx wherein x is an integer of 1 or 2.
