Study of cast microalloyed steels
Materials Science and Technology, 2003AbstractImproved grades of cast steels were prepared by microalloying C–Mn–Cr steels (0.15–0.22C, wt-%) with V (0.1)+Ti (0.01) or V (0.11)+Nb (0.034)+Ti (0.01) combinations. When quenched and tempered an ultimate tensile strength (UTS) of the order of 784–1078 MPa (80–110 kg mm2) and an elongation ranging from 10 to 35% were achieved.

Microalloying by ion-beam mixing
Nuclear Instruments and Methods, 1981Abstract We have investigated ion-induced atomic mixing process as an alternative approach to conventional rapid quenching techniques for producing thin film metastable alloys. Multi-layered samples consisting of thin alternate layers of two elements were bombarded with energetic Xe ions.

Microalloyed Low-Carbon Multiphase Steels
steel research international, 2015Actual multiphase steels guarantee tensile strengths in different grades between 500 and 1000 MPa. Specifications and standards permit a wide field of chemical compositions. On one hand, carbon amounts higher than 0.12% are not seldom for grades exceeding 600 MPa tensile strength.

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).

Strengthening Nb–V microalloyed steel
Materials Science and Technology, 1991AbstractA process for producing a low pearlite steel containing small amounts of niobium and vanadium is described. Controlling rolling followed by a short annealing treatment results in grain refinement, precipitation strengthening, and matrix recovery, and produces plate with improved strength at increased toughness levels.

Niobium microalloying in rail steels
Materials Science and Technology, 2017Rail steels rely primarily for their properties on wear and rolling-contact-fatigue resistance. These properties, together with toughness, can be optimised by implementing thermo-mechanical processing during rail manufacturing, assisted by controlled additions of strong carbide-forming microalloying elements. Niobium can be used at low concentrations,

Bar production with complex microalloying
Steel in Translation, 2012New technologies for bar production have been developed at OAO Magnitogorskii Metallurgicheskii Kombinat, with the goal of reducing production costs and improving product quality. The dependence of the mechanical and operational properties of the bar produced on the microalloying and production parameters is investigated.

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.
