摘要: The positron annihilation method is a new addition to the range of sensitive complementary nuclear techniques available for materials’ research. preferential sensitivity positrons towards micro-defect domains which are not assessable by other makes it an attractive tool many materials science problems. present paper intended as brief introduction on principle measurements and its potential exemplified with help results some metallic ceramic systems.
