Özet
In this study, in order to investigate the effect of Ca addition on elevated temperature mechanical properties of AZ series magnesium alloys, 3 different alloys (AZ21, AZX211, and AZX311) were produced. Elemental and phase analyses along with microstructural characterization were performed by using XRF, XRD, optical microscope, and SEM-EDS. Tensile and wear tests were conducted at 25 degrees C, 150 degrees C, and 200 degrees C for the purpose of revealing the room and elevated temperature service condition performances of the alloys which were followed by the application of hardness measurement applied at 25 degrees C to the alloys. It was observed that while the microstructure of AZ21 alloy contained only alpha-Mg, the microstructures of AZX211 and AZX311 alloys contained alpha-Mg, (Mg, Al)(2)Ca and Al2Ca due to the addition of Ca. Furthermore, the strengths of AZX211 alloy were better for all temperatures, especially at 25 degrees C with 152 +/- 5.4 MPa tensile strength and 95 +/- 4.1 MPa yield strength, and also it had the lowest hardness (51.6 +/- 1.3 HV) as compared to the other alloys. When all temperatures wear rates were compared, the AZX211 alloy was understood to have a stable wear rate for all applied load values, especially under 40 N applied load for 22.826 +/- 0.730 x 10(-3) mm(3)/m at 25 degrees C, 21.201 +/- 0.758 x 10(-3) mm(3)/m at 150 degrees C and 24.768 +/- 0.326 x 10(-3) mm(3)/m at 200 degrees C test temperatures, respectively.
