High-Strength, Low-Alloy Steels
Science, 1980High-strength, low-alloy (HSLA) steels have nearly the same composition as plain carbon steels. However, they are up to twice as strong and their greater load-bearing capacity allows engineering use in lighter sections. Their high strength is derived from a combination of grain refinement; precipitation strengthening due to minor additions of vanadium,

Springback in high-strength steels
Journal of Applied Metalworking, 1981A study has been made of springback after the forming of a simple flange in CRLC, SAE 950X and 980X, and a dual-phase steel; the variables investigated were material thickness, die gap, anvil radius and prior cold work. It was found that springback increased as the strength of the steel, anvil radius and die gap increased and as the sheet thickness ...

<div class="htmlview paragraph">The development of new high-strength steels is an important topic at ThyssenKrupp Steel. Application of these new steel grades in automotive production can support significant weight reduction in order to achieve future CO<sup>2</sup> targets. However, it is necessary to consider certain requirements of

Passivation Layers of Ultra-Advanced High Strength Steels and High Strength Steels
The fundamental ambition of this thesis is to assess the effects of chemical com-position, temperature and elapsed time reaction on scale formation. The control of oxidation rates and oxide morphology are focal points of interest along with the evolution and formation mechanisms of scale morphology with time and temperature.openaire +2 more sources

1. Weldable high-strength steels can be divided into two groups: those with a ferrito-pearlitic structure and those consisting of acicular upper troostite. Steels of the first group are used either as-rolled or normalized. Their tensile strength is 55–71 kg/sq. mm; their weldability and impact toughness are good.

This chapter is concerned with the advanced high-strength steels (AHSS). The focus is on AHSS of second generation—the high-alloy austenitic steels with twinning-induced plasticity (TWIP) and transformation-induced plasticity (TRIP). For both groups, the state-of-the-art knowledge regarding the thermodynamic aspects, the deformation behaviour and the ...

High Strength Steels and Coatings
The development of high-strength steel grades is aimed at reducing the thickness of steel plates and the weight of assembled objects. This reduction in thickness makes the need for corrosion protection all the more critical. Zinc-rich coatings have emerged as the dominant solution because they provide two mechanisms of corrosion protection: a barrier ...Marie-Laurence Giorgi +1 more
