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).

Compositional evolution of microalloy carbonitrides in a Mo-bearing microalloyed steel
Scripta Materialia, 2013Molybdenum is known to affect microalloy precipitate evolution during processing in ferrite and austenite, but a unified explanation of the role of Mo in precipitate evolution is still lacking. Experiments and thermodynamic calculations indicate that Mo is incorporated into (Nb,Mo)(C,N) precipitates both in the hot-rolled condition and after reheating ...

Ductility of Microalloyed Steels during Hot Deformation
Materials Science Forum, 2010The ductility behaviour experienced by steels for linepipe (LP) applications in a temperature range generally from 700°C to 1200°C is a widely studied subject in steel research, especially for its implication on cracking during continuous casting and rolling.

ON THE HARDENABILITY OF AN INTERCRITICALLY HEAT TREATED MICROALLOYED STEEL
Instrumentation Science & Technology, 2010Dual phase steel has become an important engineering material to be used in structural and automotive applications due to its good combination of strength, ductility, and formability. In this study, hardenability of a low carbon and microalloyed steel was investigated by using the standard Jominy End Quench Test at four different quenching temperatures.

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
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.
