Large abnormal grains were produced in molybdenum (Mo) through plastic deformation at elevated temperatures in the vicinity of 0.6 TH. Without concurrent plastic deformation, significantly higher temperatures are required to initiate abnormal grain growth in this material. The process of producing abnormal grain growth through plastic deformation is known as dynamic abnormal grain growth (DAGG). DAGG stops when plastic deformation ceases. The growth of some, but not all, abnormal grains produced by DAGG can resume during static annealing for extended periods of time. These grains grow much more slowly during static annealing and do not grow into undeformed regions. The influence of microstructure and abnormal grain orientation on growth during static annealing following DAGG will be discussed.
