Abstract

Nanostructured alloys consisting of 10, 20 and 30 at.% Y in Pd were synthesized by high-energy ball-milling to determine the thermal stability and hydriding behavior of different alloy compositions. Adding 10 at.% Y to the Pd resulted in a nanoalloy that was stable against grain growth to above 400°C, as compared to 200°C for ball-milled pure Pd. Adding 20 and 30 at.% Y resulted in a supersaturated solution of Y in Pd and in the Pd₃Y intermetallic phase, respectively. Both the supersaturated solution and the intermetallic phase exhibited stability against grain growth to above 400°C and interesting phase segregation behavior in heat treatment. In addition to stabilizing against grain growth, doping the Pd with Y also suppressed the α → β phase transition.
