  • Patent number: 8016957
    Abstract: The grain size of magnesium alloys is effectively refined and made smaller by the addition of a small amount of titanium. The effect of the reduction of grain size is often an improvement in the strength and processability of a cast magnesium alloy. Often less than about 0.1% by weight of titanium need be used. It may be preferred to incorporate the titanium with another alloying constituent (such as aluminum) for addition to a melt of a magnesium base alloy.

  • Patent number: 7972663
    Abstract: A method of forming a silicon nitride layer is described. According to the present invention, a silicon nitride layer is deposited by thermally decomposing a silicon/nitrogen containing source gas or a silicon containing source gas and a nitrogen containing source gas at low deposition temperatures (e.g., less than 550° C.) to form a silicon nitride layer. The thermally deposited silicon nitride layer is then treated with hydrogen radicals to form a treated silicon nitride layer.
