Microalloyed steels for high-strength forgings
La Metallurgia Italiana, 2010In the past thirty-five years, two families of microalloyed (MA) steels have been developed for high strength barand forging applications. The first family was introduced in 1974 and represented the medium carbon steelsto which were added small amounts of niobium or vanadium.

Impact Properties of Microalloyed Steel
2000Impact properties of two grades of microalloyed steel (Re>500MPa), work hardened by static and dynamic uniaxial tension are presented. Properties are analysed by impact testing at very high impact loading rate (v=785m/s) and by fatigue testing at ultrasonic, very high frequency (20kHz).

High-temperature plasticity of microalloyed steel
Steel in Translation, 2016The influence of continuous casting of steel on the high-temperature plasticity of microalloyed steel is investigated. The Gleeble-3800 system is used for the physical modeling of the steel’s hot plasticity. The temperature ranges of plasticity are determined in different conditions of slab cooling in the continuouscasting machine.

Microalloyed High Carbon Wire Steels
2014Increased demands for weight reduction in a variety of structures and applications are stimulating the development of wire products with increased strength. Boron, Vanadium, and Niobium microalloying of high carbon wire steels will be discussed, in particular alloying effects on austenite decomposition and pearlite transformation kinetics.

Microstructural Control in Microalloyed Steels
1979High-strength low-alloy (HSLA) steels constitute a classic metallurgical development in which alloying additions and thermomechanical processing have been brought together effectively to attain desired combinations of engineering properties through microstructural control.

HOT DUCTILITY OF MICROALLOYED STEELS
La Metallurgia Italiana, 2008The loss in ductility experienced by microalloyed steels at temperatures generally ranging from 700 to 1100°C is a widely studied subject in steel research. The hot ductility behaviour of steels is usually measured through the reduction of area of the samples after hot tensile tests performed up to fracture.

Induction Heating of Microalloyed Forging Steels
Materials Science Forum, 1998Microalloyed steels are being used more extensively by the forging industry in a production process that requires a more precise control of billet temperature when delivered to the forging press or forging hammer. Although induction has become the prime billet heater of choice for most forgers, some of the older induction installations are not able to ...

Hydrogen embrittlement of Microalloyed structural steels
Materials and Corrosion, 1994AbstractThe effect of Cr, Mo, V, Nb, Mn, their carbides and different microstructures on the corrosion and hydrogen uptake of two fine‐grained microalloyed steel grades has been investigated. In practice, fine‐grained structural steels appear to be more or less susceptible to hydrogen induced cracking, probably because of various strong interactions ...
