Abstract
In one aspect of the invention, an alloy includes a first element comprising magnesium (Mg), titanium (Ti), zirconium (Zr), chromium (Cr), or nickelaluminum (NiAl), a second element comprising lithium (Li), calcium (Ca), manganese (Mn), aluminum (Al), or a combination thereof, and a third element comprising zinc (Zn). According to the invention, nanoscale precipitates is produced in the magnesium alloy by additions of zinc and specific heat-treatment. These precipitates lower the energy for dislocation movements and increase the number of available slip systems in the magnesium alloy at room temperature and hence improve ductility and formability of the magnesium alloy.
