A field ion microscope study of some tungsten-rhenium alloys

Abstract

Field ion microscope observations have been made of the effects of alloying tungsten with rhenium, and a series of alloys have been imaged and examined. The structure of two alloy grain boundaries has been determined, stacking-faults imaged and a [sgrave]-phase precipitate particle examined. Tentative explanations are put forward to account for the micrographs obtained and it is concluded that under suitable conditions atomic species could be distinguished.
