The invention relates to an alloy, in particular a light metal alloy, having an alloy composition with at least three components and a eutectic structure that is obtained by cooling the alloy from a liquid state to a solid state, under the condition that a composition of the alloy lies in a field around a pseudoeutectic point (pE) of a phase diagram of the alloy, so that at least 85 mol % eutectic structure is present in the alloy. The alloy also relates to a method for producing an alloy of this type.

A magnesium-lithium-based alloy contains Mg, Li, and Al, and a sum of a content of the Mg and a content of the Li is 90% by mass or more. The magnesium-lithium-based alloy contains Ge.

The invention relates to a magnesium alloy. To obtain a magnesium alloy which exhibits both a high strength and also a high deformability, a magnesium alloy is provided according to the invention, comprising (in at %) 15.0% to 70.0% lithium, greater than 0.0% aluminum, and magnesium and production-related impurities as a remainder, wherein a ratio of aluminum to magnesium (in at %) is 1:6 to 4:6. The invention also relates to a method for producing the magnesium alloy.

Disclosed herein are magnesium alloy based objects and methods of making and use thereof. For example, disclosed herein are methods of making a magnesium alloy based object, the methods comprising: heating an object comprising a preliminary magnesium alloy at a first temperature for a first amount of time, the preliminary magnesium alloy comprising a first intermetallic phase, a second intermetallic phase, and an alloy phase, to thereby substantially dissolving the first intermetallic phase into the alloy phase to form an object comprising an intermediate magnesium alloy, the intermediate magnesium alloy comprising the second intermetallic phase and the alloy phase; and heating the object comprising the intermediate magnesium alloy at a second temperature for a second amount of time to thereby substantially dissolving the second intermetallic phase into the alloy phase and minimizing incipient melting of the alloy phase to form the magnesium alloy based object.

The following two problems arise when carbon is added to a starting material powder in the process of production of an MgB.sub.2 superconductor: (1) an impurity phase increases; and (2) the degree of substitution of carbon at boron sites is spatially non-uniform. This superconductor production method comprises: a mixing step of mixing a starting material powder and an additive; and a heat treatment step of heat-treating the mixture prepared in the mixing step. The starting material powder is MgB.sub.2 powder or a mixed powder of magnesium and boron, and the additive is an Mg—B—C compound containing three elements of magnesium, boron and carbon.

A magnesium alloy contains a small amount of lithium, zinc, calcium, and manganese. For example, the magnesium alloy may include between 1-5 wt. % lithium, between 0.2-2.0 wt. % zinc, between 0.1-0.5 wt. % calcium, and between 0.1-0.8 wt. % manganese. These alloying elements are all nutrient elements, such that the present alloy can be safely broken down in vivo, then absorbed and/or expelled from the body. Li, Zn, Ca and Mn each contribute to solid-solution strengthening of the alloy. Ca also acts as a grain refiner, while Zn and Ca both form strengthening and corrosion-controlling intermetallic compounds. Optionally, the alloy may also include a small amount of yttrium for added strength and corrosion resistance.
