Impression creep of Mg-1.5Ca and Mg-3.0Ca alloys
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. Cr...

| الملخص: | 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-1 for Mg-1.5Ca and Mg-3.0Ca samples, respectively. Microstructures in both alloys showed eutectic mixtures containing fine Mg2Ca and a-Mg phases at both interdendritic and inter-grain regions. © Medwell Journals, 2016. |
