The mechanical properties of AU alloy (2.1% Al, 5.3% Zr, 0.35% O) were studied at room temperature and at elevated temperatures, along with the thermal stability, long-term strength, and fatigue strength of this alloy. Annealing of the alloy over 950 deg C reduces ductility. At lower temperatures, the mechanical properties remain almost unchanged in comparison with specimens annealed at 800 deg C, the lowest temperature used. The alloy was found to be thermally stable at 400, 500 and 800 deg C for holding times up to 1000 h. Short- term strength testing showed that the tensile strength stayed at 40 kg/mm/sup 2/ up to 500 deg C, then -dropped sharply, the ductility increasing. However, deformation aging in the presence of interstitial atoms causes the ductility of the alloy to drop noticeably between 400 and 500 deg C. (JPRS)
