Influence of Thermomechanical Sequences on the Mechanical Properties of DP 800 Steel [PDF]
Materials Research, 2021 Abstract The influence of thermomechanical processing sequences on the microstructure and mechanical properties of Advanced High-Strength Steels (AHSS) DP800 steel was studied. Initially, the phase transformation domains were identified by dilatometry. Based on the identification of these domains, some thermomechanical sequences were produced.

Investigation on the effect of machining parameters on 42CrMo4 DPS steels
Cogent Engineering, 2023 AbstractMachining 42CrMo4 martensite—ferrite dual phase steel is challenging due to its high hardness and it is essential to determine the favorable requirements for the optimum machining condition. The ability to alter the martensite quantity in dual phase structure of steel leading to variation in bulk hardness is the motivation for machinability ...

The differences of damage initiation and accumulation of DP steels: a numerical and experimental analysis [PDF]
International Journal of Fracture, 2020 AbstractMany studies have examined the damage behaviour of dual-phase steels already. It is a topic of high interest, since understanding the mechanisms of damage during forming processes enables the production of steels with improved properties and damage tolerance.

Effect of strain rate on the hydrogen embrittlement of a DP steel [PDF]
EPJ Web of Conferences, 2018 Advanced high strength steels (HSSs), such as dual phase steels, are widely used in the automotive industry due to their excellent combination of strength and ductility. In certain applications, they might be exposed to hydrogen (H) which is known to be detrimental for the deformation. H embrittlement (HE) is still not fully understood.
