Nomenclature for strain-induced boundaries in hot and cold working

Recent advances in the analysis of strain-induced boundaries in cold working have led to a strong evolution in understanding of their nature and in nomenclature. This has impacted on the hot working domain, instigating a re-examination of microstructural behavior and pressure to revise the terminology. While hot working involves high strain rates and strains, it shares with creep the development of a steady state regime at relatively low strains. The development of substructure and response to Taylor polycrystalline constraints have essential differences from those in cold working, so the different boundary character warrants retention of their traditional names.
