The alloys were produced under protective atmosphere by a cold chamber high pressure-die casting process. Microstructure analysis of the samples were carried out by scanning electron microscopy (SEM), an energy-dispersive spectrometer (EDS) and X-ray diffraction (XRD). X-ray difractometry revealed that the main phases are alpha-Mg and MgZn in the whole alloys. Also, the Mg17La2 phase was observed with addition of La. Hardness and tensile properties were examined to investigate the mechanical properties. Results showed that the yield strength and nanohardness of main alloy were improved from 40 % (100 MPa to 140 MPa), 24 % (from 1.04 GPa to 1.29 GPa) with addition of 4 wt.% La, respectively. However, elongation was decreased with increasing of La content.eninfo:eu-repo/semantics/closedAccessMechanical-PropertiesMicrostructureIntermetallicsBehaviorInvestigation of Biodegradable Ternary Mg-Zn-La Magnesium AlloysConference Object193510.1063/1.50259772-s2.0-85044008833Q4WOS:000445956100023N/A
