dc.description.abstractSuitable and complete sets of stress-strain curves significantly affected by dynamic recrystallization were analyzed for 11 different iron, copper, magnesium, titanium or nickel based alloys. Using the same methodology, apparent hot deformation activation energy Q(p) and Q(ss) values were calculated for each alloy based on peak stress and steady-state stress values. Linear dependence between quantities Q(p) and Q(ss) was found, while Q(p) values are on average only about 6% higher. This should not be essential in predicting true stress of a specific material depending on the temperature-compensated strain rate and strain.cs
