The effects of C and N on the work-hardening behaviors were compared in metastable austenitic steels which varied amounts separately added (Fe-18%Cr-8%Ni-(C,N) alloys). Although both suppressed deformation-induced martensitic transformation during tensile deformation due to their austenite-stabilizing effect, they enhanced work hardening steels. Comparison C-added N-added revealed that addition...

The overwhelming impact of complex-phase microstructures to mechanical response in multiphase steels requires accurate constitutive properties the individual phases. However, precise prediction phase their is critical and sophisticated, commonly multiscale characterizations numerous approximations. In this work, by employing full information semi-empirical analytical models, we accurately predi...

The effect of the initial microstructure and soft annealing temperature on cementite spheroidization softening is studied an AISI 5140 hot-rolled wire. In coarse pearlite (λ: 0.27 μm), progresses slowly under subcritical treatment, does not achieve minimum G2/L2 IFI rating defined in ASTM F2282 to be used cold forming operations any treatment studies. Fine 0.10 μm) upper bainite microstructures...

Electrical steels are important alloys widely used in electrical instruments. The magnetic properties and low core loss of grain oriented silicon steels are closely related to the sharpness of Goss texture ({110} ).The direction of is the softest direction for magnetism.  In this work, the microstructure and dependence of orientation density along the major texture fibers on the applied cold ro...

Abstract A wire of a β-Titanium alloy known as Gum Metal was cold rolled to reduction 80% and heat treated for times in the range 3-120 minutes at fixed temperature 740 °C yield set partially recrystallized microstructures. The recrystallization course evaluated by light optical microscopy Electron Backscatter Diffraction, based on which kinetics analysed using Johnson-Mehl-Avrami-Kolmogorov (J...

In this paper, how structure-sensitive parameters derived from the hysteresis loop, like coercive field, remanent induction, and hysteresis losses, can be used to characterise recovery and recrystallization in cold rolled Ti-Nb stabilised interstitial free ultra low carbon steel is shown. The effect on hysteresis measurements of isothermal annealing treatments applied to industrially cold rolle...

The concept of cold-formed light steel framing construction has been widespread after understanding its structural characteristics with massive research works over the years. Connection serves as one of the important elements for light steel framing in order to achieve its structural stability. Compared to hot-rolled steel sections, cold-formed steel connections perform dissimilarity due to the...
