Hydrogen in microalloyed steels

Steel Research, 2001
To understand and control hydrogen induced cracking and stress corrosion cracking, the processes of hydrogen absorption, diffusion and trapping are of interest. Fundamentals of these processes are described and of the determination of permeation coefficient, diffusivity and solubility of H in iron and steels, using the electrochemical double cell. With

Microalloyed steel for railroad wheels

Steel in Translation, 2008
Radical improvement in the reliability and longevity of railroad wheels at high train speeds and loads depends primarily on improvements in the properties of wheel steel: increased static and cyclic strength, high- and low temperature strength, and wear resistance, and low likelihood of the formation of martensitic surface zones.

Plasma nitriding of microalloyed steel

Surface and Coatings Technology, 1995
Abstract 3icroalloyed or high strength low alloy (HSLA) steels are carbon-manganese steels containing small amounts of Nb, V or Ti. The excellent mechanical properties of these alloys, particularly high yield strength, usually obviate the need for expensive quench and tempering operations.

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.

Microalloyed Forging Steels

Materials Science Forum, 1998
Microalloyed forging steels have been developed to improve the competitiveness of wrought steel components, especially in the automotive sector, by achieving the desired properties in the as-forged condition, thus eliminating the need to subsequently heat treat, straighten and stress relieve the previously specified low alloy steels.
