Impact properties of microalloyed steels
Metalurgija, 2000 Impact properites of two grades of microalloyed steels (Re>MPa) work hardened by static and dynamic inuaxial tension are presented. Properties are analysed by impact testing at very high impact loading rate (v=785 m/s) and by fatigue testing at ultrasonic, high frequency (20 kHz).

Niobium in Microalloyed Rail Steels
, 2017 Rail steels rely primarily on possessing adequate wear and rolling contact fatigue resistance. These properties, together with the toughness, can in principle be optimized by implementing thermomechanical processing assisted by controlled niobium additions. The purpose of the current work is to develop a Nb-microalloying strategy in the context of high-
