Constitutive equations including an Arrhenius term have been commonly applied to steels
with the objective of calculating hot rolling and forging forces. The function relating stress …

Conclusions The fundamental mechanisms responsible for the low rate of strain hardening
during high temperature deformation and for a steady state of flow at high strains have been …

This reference provides descriptions on techniques relating to the hot deformation of
aluminum alloys. It provides detailed explanations on how this process relates to creep …

Hot torsion tests, in the range 250–450° C and 0.05–5.0 s− 1, were performed on Al Zn
Mg Cu alloys (7012 and 7075), which had been direct chill cast, homogenized and …

The effects of multiple microalloy additions on the dynamic recovery and recrystallization
behavior of austenite were investigated in a series of 0.05% Cl. 25% Mn steels. The steels …

Deformation of aluminum up to strains of 4 at elevated temperature results in a steady state
regime in which the substructure remains equiaxed and approximately constant in …

A mechanism of dynamic softening of ferrite was studied in a 21Cr-10Ni-3Mo
austenite/ferrite duplex stainless steel subjected to torsion at a strain rate of 0.7 s− 1 at …

High-temperature plastic deformation and dynamic recrystallization of AZ31 extruded (EX)
and heat treated (FA) alloy was investigated in the temperature range between 200 and …

The AA 5083 alloy was deformed in torsion in the ranges 300–500° C and 0.1–1 S− 1 to a
strain of 5. The flow stress as a function of strain rose to a maximum value then gradually …

Hot torsion continuous tests were performed on a cold work tool steel (A2) and a high speed
steel (M2) in the temperature range of 900–1150° C at strain rates of 0.1, 1 and 4 s− 1. The …
