| A study of ageing effects on the structure of Cu-Zn-Sn shape memory alloys was performed using the 119Sn Mössbauer spectroscopy and positron annihilation techniques (the positron lifetime, and Doppler broadening line-shape S-parameter measurements). Two stages of ageing at 200°C connected with redistribution of Sn atoms were observed. |
