Magnesium alloy based objects and methods of making and use thereof

A magnesium alloy based object made by a method, the method comprising:

• heating an object comprising a preliminary magnesium alloy at a first temperature for a first amount of time;
• wherein the preliminary magnesium alloy comprises a first intermetallic phase having a melting temperature, a second intermetallic phase having a melting temperature, and an alloy phase having a solidus temperature;
• wherein the melting temperature of the first intermetallic phase is lower than the melting temperature of the second intermetallic phase and the solidus temperature of the alloy phase;
• wherein the melting temperature of the second intermetallic phase is higher than the solidus temperature of the alloy phase;
• wherein the first temperature is from 10° C. to 50° C. above the melting temperature of the first intermetallic phase, below the melting temperature of the second intermetallic phase, and below the solidus temperature of the alloy phase;
• and
• wherein the first amount of time is from 10 to 15 hours;
• 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;
• wherein the second temperature is from 10° C. to 20° C. above the melting temperature of the second intermetallic phase;
• and
• wherein the second amount of time is from 1 hour to 3 hours;
• 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.
