PETCH ANALYSIS OF HYDROGENATED TANTALUM SHEET.
Abstract
The anomalous behavior in ductility exhibited by tantalum, at low temperature, with hydrogen as an impurity was investigated utilizing a Petch-type analysis. The change in lattice friction stress and dislocation locking stress parameters were determined through a temperature range from room temperature to -196C. The results of the investigation show the locking stress remained essentially unchanged by small hydrogen additions while the lattice friction stress increased significantly at temperatures below -78C.
