Abstract Scope Mechanical deformation is being used to probe defects related to processing and aging in Pu-Ga (1-7 at pct) alloys ranging from 1 to 11 years of age. Stress relaxation measurements were performed using quasi-static compression tests in conjunction with first principles strengthening mechanisms concepts to provide insight into dislocation-defect interactions related to strength. Strength changes associated with grain size, age, and heat treatment conditions were related to measurable changes in the internal and effective stress components of the flow stress. Internal friction was measured using resonant ultrasound spectroscopy to detect Debye peaks related to mobile defects in δ-Pu. Further analysis of the Debye peaks provide the defect activation energy of diffusion and mean residence time, which can help inform material models. Characterization of defects detected by stress relaxation and internal friction will further our fundamental understanding of Pu aging in support of a safe and reliable nuclear stockpile.
