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.

Development of Molybdenum Alloy with High Toughness at Low Temperatures
Materials Transactions, JIM, 1996 The irradiation embrittlement and recrystallization embrittlement of molybdenum and its alloys are major problems for their application to plasma facing components in the future fusion reactors. In order to overcome the problems, the basic idea of alloy design and microstructure control was proposed, and a TiC dispersed molybdenum alloy was developed ...
