Investigations on a ternary Mg-Ca-Si wrought alloy extruded at moderate temperatures

Wrought Magnesium alloys are lightweight structural materials with excellent specific strength. Recently, Ca has received increased attention as a main alloying element in Mg alloys providing advantages in processing and microstructural evolution. Especially the synergetic use with additional elements such as Al, Zn or Sn has shown improved performance in extruded profiles, as it promotes the formation of intermetallic phases and a stable, fine-grained microstructure. Superior mechanical properties can be achieved with these alloys when processed at moderate temperatures. Here we present an investigation into the processing of an Mg-Ca-Si alloy, discussing the alloying principle as well as microstructural and mechanical behavior.

Automated summary

Wrought Magnesium alloys with Ca as the main alloying element showed improved performance in processing and microstructural evolution when synergistically combined with additional elements. High mechanical properties can be achieved when processed at moderate temperatures.
