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.

Impact toughness of multilayer steel materials at low temperatures
IOP Conference Series: Materials Science and Engineering, 2019 Abstract The results of a number of studies show that there are ways to drastically change the temperature dependence of the impact strength of structural steels, which at first glance have a paradoxical character. It was established that when the test temperature decreases down to cryogenic temperatures, the work of failure of impact ...
