Abstract

The results are presented of the first studies to be carried out on 4He retention under mechanical deformation of isoferroplatinum (Pt3Fe) from a unique placer deposit at the Konder and Uorgalan rivers and from indigenous shows of the alkaline–ultrabasic Konder Massif (Khabarovsk krai, Russia). It was found that the deformation of Pt3Fe of the Pm-3m cell resulted in structural transformations with the appearance of domains and subsequent conversion into native platinum (Pt, Fe) of the Fm-3m cell.
