Abstract: Abstract A mean-field model based on the elasticity theory of point defects has been developed to investigate the role of uniform stress fields on the long-range ordering of carbon atoms in bct-iron. From an analysis… read more here.

DOI: 10.1016/j.ijplas.2017.12.009
Abstract: Abstract This paper addresses the impact of adding 0.14 wt% of vanadium to a fine-grained DP1300 steel, particularly in terms of damage and ductility. Variants with and without V were heat treated so as to obtain… read more here.

DOI: 10.1016/j.matlet.2020.128820
Abstract: Abstract Segregation behavior and capturing mechanism of phosphorus (P) in dual-phase steel were systematically investigated by Atom probe tomography (APT). The dual-phase steel is composed of lath martensite, irregular ferrite and MC-carbide (M = Ti, Mo). The… read more here.

DOI: 10.1016/j.measurement.2018.12.106
Abstract: Abstract In this study, a simple classification scheme based on image processing is proposed to categorize optical microstructures of dual-phase steels with varying morphology (i.e., shape, size and distribution) of ferrite-martensite phases. Dual-phase microstructures with… read more here.

DOI: 10.1016/j.mtcomm.2020.100895
Abstract: Abstract It is generally accepted that reducing the strength difference between soft ferrite and hard martensite in a dual-phase (DP) steel can delay fracture during plastic deformation. However, it is still not clear whether the… read more here.
