A comparative study on constitutive modeling of hot deformation flow curves in AZ91 magnesium alloy
Modeling the flow curves of materials at elevated temperatures is the first step in mathematical simulation of the hot deformation processes of them. In this work a comparative study was provided to examine the capability of three different constitutive equations in modeling the hot deformation flow curves of AZ91 magnesium alloy. For this, the Arrhenius equation with strain dependent constants...
متن کاملFlow Behavior of SP-700 Titanium Alloy During Hot Tensile Deformation in α+β and β Phase Regions
In this paper, in order to study the flow behavior and elongation of as-cast ingots of SP-700 titanium alloy, hot tensile test was done in α/β dual phase and β single phase regions using strain rate of 0.1 s-1. Results showed that the hot tensile behavior of SP-700 in the α/β dual phase region (700-900 ºC) was different from the β single phase one (950-1100 ºC) due to the nature of alpha and be...
متن کاملEffects of Carbon on the Microstructure and Hot Deformation Behavior
The effects of carbon content on the dynamic and static softening mechanisms of Ti microalloy steels were investigated both in ferrite and austenite regions. 
The results obtained showed that recrystallization rate decreased as the percentage of carbon content was increased from 0.0035 to 0.110. This is due to the Ti(CN) and TiC precipitates and also the free carbon content. In the ferrite r...

متن کاملMODELING THE HOT DEFORMATION FLOW CURVES OF API X65 PIPELINE STEEL USING THE POWER LAW EQUATION
Till now, different constitutive models have been applied to model the hot deformation flow curves of different materials. In this research, the hot deformation flow stress of API X65 pipeline steel was modeled using the power law equation with strain dependent constants. The results was compared with the results of the other previously examined constitutive equations including the Arrhenius eq...
