This study presents an investigation that characterizes the evolution of the dynamically
recrystallized structure and flow behavior of FB 2 rotor steel during hot deformation in the …

The use of appropriate forming processes allows to obtain materials of required shapes,
structures and properties. The technological conditions of the process can be optimized in …

In this study, a comparison between the well-established Lagrangian approach and the
Arbitrary Lagrangian–Eulerian (ALE) approach is presented. This comparison aims to verify …

Powder metallurgy nickel-based superalloys have been widely used in high temperature
applications. For these materials, a fully dense and fine-grained microstructure is important …

The present investigation has been conducted to study the effect of the austenitic grain size
(AGS) on the flow stress behaviour of austenite, deformed in a wide range of temperatures …

It is a common practice in pressure forming to make an Equal Channel Angular Extrusion
(ECAE) of a workpiece through a die with channel intersection angle 2θ= 90 using a …

The flow behavior of 5754 aluminum alloy was researched using the plane strain
compression test for the range of 300–500° C and 0.1–10 s− 1. The experimental flow …

A comparative study has been carried out on the capability of the modified Johnson–Cook
(JC) models and a strain-compensated hyperbolic sine constitutive model to predict the flow …
