DEFECT PRODUCTION, INTERNAL FRICTION, AND YOUNG'S MODULUS IN DEUTERON IRRADIATED TUNGSTEN (thesis). Scientific Report No. 1

Technical Report ·
OSTI ID:4746729
Radiation-induced defects in W are explained mathematically. The effects of 15-Mev deuterons on the mechanical properties of W are discussed. Orradiations were performed in the external beam ductwork of a cyclotron, and experiments were carried out in a cryostat capable of maintaining temperatures between 77 and 300 deg K. Determination of beam flux and energy is discussed. Techniques of measuring electric resistance, internal friction, and elastic modulus of W samples are detailed. The energy dependence of radiation damage in W was studied and results are given. Radiation effects on internal friction and Young's modulus, and the effects of annealing on internal friction are discussed. (R.J.S.)
