Effect of Ca and Ce on Wear Behavior of Hot-Rolled AZ31 Mg Alloys
(Polish Acad Sciences Inst Physics, 2020) Kara, I. H.; Yousef, T. A. I.; Ahlatci, H.; Turen, Y.
In this study, Ca and Ce added AZ31 Mg alloys were produced by low pressure die casting method and the following materials were rolled at 400 degrees C. The wear properties of materials were investigated by wear test method according to ASTM-G133 in a dry condition at room temperature. The microstructure of samples investigated by light optical microscopy and scanning electron microscopy both before and after corrosion tests. The twins and dynamic recrystallization (DRX) and the alloying elements play an important role to impart the final wear resistance of investigated materials.
Effect of Lanthanum on the Microstructure and Mechanical Properties of Hot-Rolled Magnesium Alloy AZ31
(Springer, 2019) Kara, I. H.; Ahlatci, H.; Turen, Y.; Sun, Y.
The effect of lanthanum additions (0.2 - 1.0%) on the microstructure and mechanical properties of magnesium alloy AZ31 is studied after hot rolling with deformation of 15 and 30%. The microstructure is analyzed by the methods of x-ray diffractometry, optical microscopy and scanning electron microscopy. The mean values of the ultimate strength, elongation and contraction are determined in tensile tests.
