Low cycle fatigue and mechanical properties of magnesium alloy Mg–6Zn–1Y–0.6Ce–0.6Zr at different temperatures
Highlights Room and elevated temperature LCF data and mechanical properties reported. Fractographic and metallographic analyses were conducted. Favorable LCF behavior at higher temperature, high tensile strength and elongation. Different deformation mechanisms at 200°C were noted and explained. Mg alloy at hand susceptible to stress concentrations at room temperature.
Abstract The paper deals with low cycle fatigue (LCF) and mechanical properties of Mg–6Zn–1Y–0.6Ce–0.6Zr alloy at both room and elevated temperatures. Fractural microstructures of the test specimens were also analyzed. Based on the experimental results some guidelines about the application of the Mg alloy are provided. A detailed review of existing literature on LCF of other Mg alloys is provided and comparison with appropriate results of other authors was made. Due to scarcity of results, special attention is given to the low cycle fatigue properties at elevated temperatures. LCF results are assessed relative to the loading defined as a fraction of the ultimate tensile stress. With such criterion, it can be said that increase in temperature leads to the more favorable environment for low cycle fatigue of Mg alloy at hand.
