Je. Frackowiak et al., POSITRON-ANNIHILATION STUDY OF THE AGING EFFECTS IN THE CU-ZN-SN PARENT PHASE, Acta Physica Polonica. A, 88(2), 1995, pp. 327-332
A study of ageing effects on the structure of Cu-Zn-Sn shape memory al
loys was performed using the Sn-119 Mossbauer spectroscopy and positro
n annihilation techniques (the positron lifetime and Doppler broadenin
g lineshape S-parameter measurements). Two stages of ageing at 200 deg
rees C connected with redistribution of Sn atoms were observed.
