Advanced high-strength steel (AHSS) steels are relatively not very well weldable because of the dominant martensitic structure with coarse ferrite and bainite. The utmost difficulty in welding these is their tendency to crack both heat affected zone (HAZ) weld. significant disadvantage that strength welded joint much lower comparison base material. Adopting new technology regarding micro-jet co...

Medium manganese (MMn) steels are a promising class of advanced high-strength (AHSS) with potential for application as vehicle panels in the automotive industry. In this study, deformation behaviour representative cold-rolled MMn steel and its dependence on processing parameters studied using uniaxial tensile testing under low-temperature hot stamping (LTHS) conditions, covering austenitisation...

Designing a new family of advanced high-strength steels (AHSSs) to develop automotive parts that cover early industry needs is the aim many investigations. One candidates in 3rd AHSS are quenching and partitioning (QP) steels. These display an excellent relationship between strength formability, making them able fulfill requirements safety, while reducing automobile weight enhance performance d...

advanced high strength steels (ahss) have recently attracted great attention because of their superior mechanical properties. a modern group of these steels, known as twinning induced plasticity (twip) steels, shows a unique combination of strength and ductility even at high rates of strain. in order to examine the functionality of such steels in dynamic loading conditions, their mechanical beh...

Advanced high-strength steels (AHSS) have become increasingly popular in the automotive industry due to their high yield and ultimate tensile strengths, enabling production of lighter car body structures while meeting safety standards. However, they some setbacks compared conventional steels, such as edge cracking through sheet thickness caused by forming components with shear-cut edges. When c...

Deformation-induced martensitic transformation (DIMT) during quasi-static loading has drawn much attention in recent years since it is considered as one of the key strengthening mechanisms advanced high-strength steels (AHSS). However, systematic investigations on at high strain-rates are scarce due to difficulties experimental designs. In this contribution, interrupted Charpy tests were used s...
