Effects Of Alloying Elements on Microstructures and Mechanical Properties of Mg-Gd-Zn-Ca Alloys

  • Chapter
Magnesium Technology 2016

Abstract

For the development of high strength extruded magnesium alloys with ignition-resistance, we had investigated the effect of addition of yttrium into Mg-Gd-Zn-Ca alloy. The addition of yttrium increased the volume fraction and thermal stability of the LPSO-like phases. The addition of yttrium also increased the tensile strength by about 70 MPa but decreased the ignition temperature by about 150 °C. In addition, the effect of the extrusion conditions on the mechanical properties of alloys has been discussed.
