## Title

- title: Quantitative characterization of local deformation-fracture behavior in ferrite-martensite
    dual-phase steels with different martensite distributions
  title_type: original
  lang: en

## Description

- description: 'Low-carbon dual-phase (DP) steels, composed of a soft ferrite phase
    and a hard martensite phase, are known as promising advanced high-strength steels
    (AHSSs) due to their high strength and good ductility at low fabrication cost.
    However, the deformation behavior of DP steels is still not fully understood because
    of their complex mixed-phase distribution and mechanical interactions between
    two phases during deformation. The present study quantitatively investigated the
    effect of martensite distribution on mechanical properties and local deformation-fracture
    behavior, using the digital image correlation (DIC) technique. Two types of DP
    structures were prepared: one with a chained martensite distribution (chained
    DP) and one with an isolated martensite distribution (isolated DP). The chained
    DP specimen exhibited a superior tensile property, achieving both high strength
    and large ductility compared to the isolated DP specimen. DIC strain analysis
    revealed that the chained DP structure showed relatively homogeneous deformation
    due to the greater contribution of martensite to plastic deformation. In contrast,
    the isolated DP specimen experienced significant strain localization in the soft
    ferrite grains. Despite high global strains, non-plastically deformed zones were
    observed in the central regions of large, isolated martensite particles. Notable
    differences in micro-void evolution were also observed between the two specimens.
    The chained DP specimen had a large number of randomly distributed micro-voids,
    ranging from 0.5 μm to 2 μm in size. In contrast, the isolated DP specimen contained
    fewer micro-voids, with some aligned at an angle of ~65° to the tensile direction,
    potentially leading to early tensile fracture.'
