Enhancement of Low Temperature Toughness in Bulk Nanostructured Metals
MATERIALS TRANSACTIONS, 2013 Brittle-to-ductile transitions (BDT) in fine-grained Ti added ultra-low carbon steels were investigated. Temperature dependences of impact absorbed energy were measured using specimens with grain sizes of 0.4, 2, 9 and 70µm of which the grain sizes were controlled by heat treatments after five cycles of accumulative roll-bonding process.
