The elevated-temperature mechanical behavior of peak-aged Mg-10Gd-3Y-0.4Zr Alloy

▶ High tensile and compressive strength at RT and elevated temperatures. ▶ Between RT and 300 ̊C no fatigue sensitivity observed. ▶ The fatigue limit is between 50 and 75 MPa in the range from RT to 300 ̊C. ▶ Creep failure due to mixed cavitation and cracking, nucleation at particles. ▶ High fraction of cavitated boundaries in lower-temperature and lower-applied stress creep.
