TENSILE FRACTURE CHARACTERISTICS OF EXTRUDED INGOT BERYLLIUM AND BERYLLIUM- IRON ALLOYS
Tensile tests were carried out between 20 and 600 deg C on three extruded ingot beryllium --iron alloys, having iron contents within the range 0.024 wt% Fe -0.40 wt% Fe. The materials were tested both in the as-extruded condition, and after heat treatments designed to overage the metal with respect to its iron content. Tests were performed on transverse, as well as longitudinal specimens, with respect to the extrusion axis, in order to obtain an indication of the influence of texture variation upon the tensile behavior. Deformation and fracture types produced in the tests were studied and related to the testing temperature, purtty, thermal history, and mechanical properties of the specimen. The observations are briefly discussed in the light of current knowledge and theory pertaining to the deformation behavior of beryllium. (auth)
