摘要
Knowledge of mechanisms and governing parameters of various modes of damage to structural materials is very important in numerous aspects of practical physical metallurgy-steel production, manufacture of welded joints with required properties, or identification of damage causes in industrial accidents. The apparently simple task of finding a literature source with clear physical-metallurgical interpretation of the reasons for BDT (brittle-to-ductile transition) in steel and other body-centered cubic metals was found to be quite an intricate problem, since an unequivocal and comprehensive theoretical concept of BDT is still missing. Based on the main results of a literature survey a phenomenological explanation of the existence of BDT is presented. (C) 2013 Elsevier Ltd. All rights reserved.
