Abstract

This review will treat two recent applications of positron annihilation to metallurgical studies and will involve the measurement of the Doppler effect associated with the gamma rays emitted during positron annihilation. The applications will be: studies of the interactions of dislocations with pre-precipitates in aged Al-4 weight percent Cu single crystals and studies of the effect of hydrogen charging into polycrystalline nickel.
