Vpliv podhlajevanja na lomno žilavost martenzitnega nerjavečega jekla AISI 420 [PDF]
Cryogenic treatments have been employed over the last three decades in both tool and high-alloy steels to improve wear resistance, mainly through the transformation of retained austenite and the precipitation of fine carbides.

Influence of boron content on the fracture toughness and fatigue crack propagation kinetics of bainitic steels [PDF]
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.
