Low Temperature Neutron Radiation Damage and Recovery in Magnesium

Abstract

Abstract In magnesium neutron‐irradiated at 4.2°K the defect production and the subsequent recovery up to 350°K were studied by means of electrical resistivity measurements. Additional experimental evidence is presented from preliminary stored energy, internal friction, and electron microscope studies on neutron‐irradiated magnesium, and from electrical resistivity measurements on electron‐irradiated magnesium. The principal recovery peak occurs between 90 and 160°K.
