A PROGRAM OF BASIC RESEARCH ON MECHANICAL PROPERTIES OF REACTOR MATERIALS. Quarterly Progress Report for Period Ending March 31, 1962
Description: Studies were continued on the deformation and fabrication characteristics of reactor materials. Data were gathered on the effect of cold work on the internal friction due to dislocation relaxation oscillation. An interpretation was made of the internal-friction peak in niobium in terms of the relaxation motion of kinks on dislocations in niobium. Efforts were made to extend the technique of quantitative differential thermal analysis to cold-worked iron which was selected as the most readily treated representative of the body- centered-cubic structural metals. Refinements were made in the calorimetric technique itself, leading to an improved procedure of data reduction. Results for the effects of grain size on the stored-energyrelease spectra of high-purity copper were recomputed. (M.C.G.)
