the microstructure of dual phase steels can be considered as a matrix of ferrite phase reinforced by martensite particles. recent measurements show that the mechanical properties of the ferrite phase are changed with the distance from the martensite grains. in this paper, a new method has been proposed to consider this phenomenon in finite element modeling of dual phase steels microstructure. i...

We identify the role of deformation twinning and twin–twin intersections on the strain hardening behavior of Hadfield steel single crystals using strain field measurements. In situ and ex situ strain field measurements resolved at micrometer length scales are obtained using digital image correlation. Ex situ measurements reveal that macroscopic twin-bands, which are composed of a mixture of fin...

this paper provides an overview on obtaining low-carbon ultra-fine grained dual-phase steels through rapid intercritical annealing of cold-rolled sheet as improved materials for automotive applications. a laboratory processing route was designed that involves cold-rolling of a tempered martensite structure followed by a second tempering step to produce a fine grained aggregate of ferrite and ca...

Welding hot-work tool steels, containing 0.3-0.6% of carbon, is difficult both because of the elevated carbon content and because of significant hardening resulted from large amounts of alloying elements. A development of welding technology, i.e. better quality of electrodes, modern welding devices, improved welding technologies and better steel quality, make welding of such steel types possibl...

The possibility to obtain multiphase steels with considerable fractions of retained austenite, which is of key interest for the occurrence of the TRIP effect, is investigated in steels with low amounts of Si and Al. Special emphasis is dedicated to the microstructural observation of this phase, since its volume fraction, distribution and stability, related to the carbon content, will determine ...

Mature passive films (age > 10 s) were grown in aerated saturated calcium hydroxide solution, at the open circuit, on plain steel and alloys with 9% and 22% Cr, as well as austenitic stainless steels. The materials were commercially produced concrete reinforcing steels. Differences in the polarization of the oxygen reduction reaction were evidenced. Oxygen reduction rates at moderate cathodic p...

This paper presents a study of the quasi-static and dynamic deformation behaviors of conventional and microalloyed medium-carbon steels in a wide temperature range. As strain rate increased, the flow stress increased at room temperature, but occasionally did not at elevated temperatures. The flow stress of the microalloyed steel containing precipitates was less sensitive to strain rate at room ...

The deformation response and texture evolution of aluminum alloyed Hadfield steel polycrystals is explored in the presence of high-density islocation walls. A recently developed visco-plastic self-consistent model accounting for the contribution of the dense dislocation walls to strain ardening was utilized in predicting the room temperature deformation response under tension and the accompanyi...
