Enhancement of Low Temperature Toughness in Bulk Nanostructured Metals

open access: yesMATERIALS 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.

Analysis of temperature effects near mode I cracks in glassy polymers [PDF]

open access: yes, 2005
A previous isothermal study has shown that the toughness of glassy polymers is governed by the competition between shear yielding and crazing. The present work aims at investigating loading rates for which thermal effects need to be accounted for.
