Abstract: Disclosed herein are magnesium alloys and methods of making and use thereof. For example, disclosed herein are magnesium alloys comprising: from 0 to 1.5 wt. % Zn; from 0 to 1.5 wt. % Al; less than 0.2 wt. % Ca; from 0.2 to 0.4 wt. % Ce; from 0.1 to 0.8 wt. % Mn; and the balance comprising Mg. In some examples, the magnesium alloy comprises less than 1 wt. % Zn. In some examples, the magnesium alloy comprises less than 1 wt. % Al. In some examples, the magnesium alloy exhibits substantially no incipient melting when extruded with a ram speed of from 1.00 to 10.00 ipm. In some examples, the magnesium alloy is substantially free of a Mg2Ca phase, an AlCaMg phase, an Al2Ca phase, a Ca2Mg6Zn3 phase, or a combination thereof. In some examples, the magnesium alloy is substantially free of a Mg2Ca phase.

Abstract: 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.
