Stress Relaxation of Elastic Precursor for Unalloyed Uranium and Some Uranium-Based Alloys

摘要

The new data are presented on relaxation of an elastic precursor in unalloyed depleted uranium and two its alloys. Results were obtained under low-intense explosive loading. Statistic thermofluctuational model was used for approximation of experimental data. The inversion of strength properties of the tested U-Mo and U-Fe-Ge alloys at their quasi-static and high-rate loading was revealed.
