| Abstract: | Precision measurements of positron lifetime spectra in Fe-29.5at.%Ni alloy specimens were performed to clarify the nature
of the martensitic transformation in this alloy. The forward transformation did not introduce any defects which behave as
strong trapping sites for positrons. On the other hand, the reverse transformation accompanied the production of defects,
to which the positron lifetime is sensitive, maybe dislocations. From the present results, the nature of the transformation
was discussed. |
