摘要：
Magnesium alloy is the lightest commercial metal structure material. Most of the alloys are hexagonal close-packed structure and can hardly deform in room temperature. The application of magnesium alloy is limited greatly by the low plasticity. The prismatic slip system and cone slip system of magnesium can be activated by raising the deformation temperature, then the plasticity is improved and large deformation occurs to reduce the cost of production and broaden the application. However, magnesium alloy is prone to burn and oxidize at high temperature, and the mechanical property of ignition resistance magnesium alloy is poor. Thus it is necessary to raise deformation temperature and improve the mechanical property of ignition resistance magnesium alloy in order to enlarge the application range. To get a kind of magnesium alloy owning good mechanical properties and large deformation, different contents of element Ce were added to Mg-3Y-0.6Zr basic magnesium alloy and the Mg-3Y-xCe-0.6Zr (x=0, 0.7, 1.5, 2.0, 3.0, 4.5) alloys were smelted to study the microstructure, mechanical properties, element distribution and fracture morphology of alloys by optical microscopy (OM), tensile test, energy dispersive spectroscopy (EDS) and scanning electron microscopy (SEM). The study showed that the addition of Ce in Mg-3Y-0.6Zr alloy could refine the microstructure and improve the mechanical properties of the alloy. Mg-3Y-1.5Ce-0.6Zr alloy had best properties with elongation of 21% and tensile strength of 184.71 MPa, compared with other alloys. ©2018, Editorial Office of Chinese Journal of Rare Metals.
