Description
Summary:By controlling the heat treatment temperature, the influence of aging process on the microstructure and mechanical properties of depleted uranium No.2 alloy was studied, and the dynamic properties of No.2 alloy were analyzed by Hobkinson device, and the stress-strain relationship was tested. The results show that, after solution treatment at 850 °C × 2h and aging treatment at 350 °C × 4h, the microstructure of No.2 alloy is mainly U(γ) phase and U (α /), and the dynamic yield strength of the alloy reaches the peak, which can reach 1580MPa, which is more than 40% higher than the quasi-static yield strength and has a strong strain rate hardening effect.
