Nickel, electrodeposited under different conditions and yielding different values of stress, was investigated by positron annihilation (lifetime and Doppler-broadening), Mössbauer effect and X-ray diffraction measurements. Two-component positron lifetime spectra were obtained. The first component is thought to result from bulk annihilation and trapping at single trapping centres (TC). Estimations of TC-concentrations are obtained by means of the trapping model. The second one possibly denotes annihilation at voids, the number of which is dependent on the stress in the deposit. Results of Doppler-broadening measurements support this interpretation. The Mössbauer results show differences in the magnetic orientation in the three samples examined.
