A new method for evaluation of friction in bulk metal forming
Ramin Ebrahimi,Abbas Najafizadeh +1 more
TL;DR: In this paper, a simple theoretical analysis of the cylindrical compression test has been developed so that the constant friction factor can be estimated quantitatively by using cold/hot compression test.
Journal ArticleDOI
Flow stress analysis of TWIP steel via the XRD measurement of dislocation density
TL;DR: In this paper, the rate of dislocation accumulation in tensile strained twinning induced plasticity (TWIP) steel was calculated via the X-ray diffraction (XRD) measurements and compared with other fcc metals and alloys.
Journal ArticleDOI
Constitutive relationships for hot deformation of austenite
TL;DR: In this paper, the authors derived the flow stress of a 17-4 PH stainless steel during hot compression testing using the classical hyperbolic sine equation and the self-diffusion activation energy.
Journal ArticleDOI
Hot deformation behavior of a medium carbon microalloyed steel
TL;DR: In this article, the hot deformation behavior of a medium carbon microalloyed steel was studied using the hot compression flow curves corresponding to the temperature range of 850-1150°C under strain rates from 0.0001 to 3 s −1.
Journal ArticleDOI
Prediction of the critical conditions for initiation of dynamic recrystallization
Hamed Mirzadeh,Abbas Najafizadeh +1 more
TL;DR: In this paper, the critical stress and strain for initiation of dynamic recrystallization (DRX) were determined using: (1) the strain hardening rate versus stress curve, (2) the natural logarithm of strain versus strain curve, and (3) the constitutive equations.
