Abstract:
Low cohesive strength of grain boundaries and high sensitivity of this parameter to the presence of non- metallic impurities are considered as the causes of grain boundary brittleness and poor workability of refractory fcc-metal iridium. The mechanisms of grain boundary brittleness in both contaminated and non-metallic impurity- free iridiurn are discussed in the presented paper. © 2004 Kluwer Academic Publishers.
