Vacancy migration and void formation during annealing of electron irradiated molybdenum


WE have used a combination of three techniques—resistivity, positron annihilation and transmission electron microscopy (TEM)—to examine the recovery on annealing of point defect damage introduced into high purity molybdenum by 10 MeV electron irradiation. The work produced two points of particular interest, both arising directly from the sensitivity of the positron annihilation technique to vacancy defects.
