Evolution of Microalloyed Steels Since Microalloying ’75 with Specific Emphasis on Linepipe and Plate

2015
In the four decades since the Conference Microalloying ’75 was held in Washington, DC, there has been an avalanche of development and application in almost all steel products but most notably in automotive, plate and linepipe steels. Revolutions in steelmaking, casting, rolling and accelerated cooling have all contributed to the adoption of this ...

Microalloy steels – the beginning

Materials Science and Technology, 2009
Although steels containing small amounts of vanadium or titanium had long been available, the rapid development and exploitation of microalloy steels was initiated by the recognition of the advantages of adding a small amount of niobium to C–Mn steels.

Microalloyed Steel Bars and Forgings

JOM, 1986
This paper examines microalloyed steels—steels which develop their properties in the as-received condition without requiring further heat treatment, such as quenching and tempering. Microalloyed steel bars and forgings offer a clear cut potential for cost reduction and energy savings.

Microalloying of steel with vanadium and nitrogen

Steel in Translation, 2014
The microalloying of steel with vanadium and nitrogen is experimentally studied. The goal is to compare the results when steel is alloyed with standard ferrovanadium and vanadium converter slag (with gaseous nitrogen injection) and with nitrided ferrovanadium.

Microalloying for ductility in molybdenum disilicide

Materials Science and Engineering: A, 1999
The effects of substitutional alloying on the ductility of MoSi 2 single crystals are studied. Criteria for ductility and brittleness are expressed in terms of surface energies and generalized stacking fault energy surfaces, which are calculated using first principles density functional methods.

Corrosion of Copper Microalloyed with Yttrium

Materials Science, 2003
We investigate the corrosion behavior of copper microalloyed with yttrium. We show that microalloyed copper containing 0.02–0.03% yttrium is not susceptible to intercrystalline corrosion, while the rate of general corrosion of microalloyed copper containing 0.015–0.02% yttrium is a factor of three to four lower than that of M0b oxygen-free copper.

Impact Properties of Microalloyed Steel

2000
Impact 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).

Niobium microalloying in rail steels

Materials Science and Technology, 2017
Rail 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,
