Improvement of Mechanical Properties and Work-Hardening Behavior of Intercritically Annealed Dual Phase Steel
The effect of the initial microstructure and intercritical annealing on mechanical properties and work-hardening response of a high-formability low carbon steel were studied. The work-hardening analysis was based on the modified Crussard–Jaoul method. The ferritic-pearlitic sheets showed low strength and high total elongation with the appearance of the yield point phenomenon. The occurrence of ...
متن کاملEFFECT OF SILICON CONTENT ON THE STRAIN HARDENING OF DUAL-PHASE STEELS
Abstract: In the current work, the strain hardening behavior of dual-phase steels with different silicon content (0.34- 2.26 Wt. %) was examined using the modified Crussard-Jaoul analysis. It was shown that these dual-phase steels deform in two stages over a uniform strain range. Each stage exhibited a different strain hardening exponent varying with silicon content. At the first stage, work...
متن کاملStrain hardening and heterogeneous deformation during twinning in Hadfield steel
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...
متن کاملStrain hardening behavior of aluminum alloyed Hadfield steel single crystals
Very high strain hardening coefficients (=G/23) are observed for aluminum-alloyed face-centered cubic Hadfield steel single crystals under tensile loading. Alloying with aluminum suppressed deformation twinning in two of the three crystallographic orientations studied, and transmission electron microscopy results revealed the existence of dense dislocation walls (sheets) along crystallographic ...
متن کاملStudy on Evaluation of Residual Phase Stress of the Dual Phase Stainless Steel
In this study , we measured residual stress in ground layer of ( CY+ r )dual phase stainless steel by X-ray diffraction. In addition, the influence of changing depth of cut on residual stress was investigated. It was found that residual stress in the a! phase was dependent on depth of cut, while the stress in Y phase was not affected by depth of cut. As a results of stress measurement under app...
