Influence of boron content on the fracture toughness and fatigue crack propagation kinetics of bainitic steels [PDF]
, 2016 The relatively good combination of high strength and ductility makes bainitic steels a candidate to replace many other steels in industrial applications. However, in service, ductility and strength are not up to standard requirements.

Low temperature impact toughness of structural steel welds with different welding processes
KSCE Journal of Civil Engineering, 2015 Influence of welding process and welding consumable on the impact toughness at low temperatures of the Heat Affected Zone (HAZ) and the weld metal in a structural steel weldment was investigated. A comparison of the low temperature impact toughness was made between the welded joints fabricated by Shielded Metal Arc Welding (SMAW) and Flux Cored Arc ...

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