AB  - Mg-1.5Ca and Mg-3.0Ca alloys have been successfully synthesized using argon arc melting method.
SEM and XRD were used to analyse the microstructure of the alloys. Creep resistance of the Mg-Ca alloys were
investigated using impression creep technique at 423-523 K under constant stress of 357 MPa. Creep resistance
for the Mg alloy enhanced with addition of Ca. Activation energies were calculated and found to be 142.5 and
108.4 kJ mol<sup>&#150;1</sup> for Mg-1.5Ca and Mg-3.0Ca samples, respectively. Microstructures in both alloys showed
eutectic mixtures containing fine Mg<sub>2</sub>Ca and &alpha;-Mg phases at both interdendritic and inter-grain regions.
