%X The positron lifetime in amorphous NiCrFeSiB alloy with and without hydrogen charging was measured to understand the interaction between hydrogen and point defects in amorphous structure. Free volume and vacancy group were found in the alloy as main defects. Hydrogen charging in low current density had little influence on the defect structure. High current density charging resulted in an increase of vacancy group concentration temporarily. However, the stable defect structre recovered after hydrogen escaped from the alloy.
