Tensile creep and corrosion properties of Mg-2%Ca based cast alloys Jeong-Min KIM1, Joon-Sik PARK1, Ki-Tae KIM2 1. Division of Advanced Materials Engineering, Hanbat National University, Daejeon... to Mg-2%Ca based alloy on the creep and corrosion characteristics was compared with Al addition. The creep resistance of Mg-2%Ca based alloy at 175 °C was improved by Zn addition more significantly than......
. Creep test was carried out at 200-300 ℃ under 50-120 MPa. Within the limits of the creep test conditions used in this study, the creep activation energy of the investigated alloys was in the range of 156-221 kJ/mol. The microstructure evolution during creep was characterized by optical metallography, SEM and TEM. The results show that the creep life of the alloy is increased from 52.2 to 152.8 h......
