Simufact material database for Inconel 718 powder

C B
I have few questions about the Simufact material database for Inconel 718 powder, when looking into the flow curves all I could see is the data for the plastic region, I would like to know why the Simufact didn't consider the elastic region. Also in the mechanical properties what is the input for elastic modulus for this material because am not able to find it, did you consider infinite elastic modulus? if yes, could you please explain.
 
Kindly look in to the below plot I got from a simple compression test showing true stress and true strain for IN718 powder at 20C .
In718
Could you please explain why the Simufact database doesn't have any elastic region data.

    Hello,
    you need to deactivate the thermal effects in the Forming Control \↨ Advanced \ Miscellaneous. Even with the part changing the temperature only by 7°C, this is enough to lead to an uneven distribution. Rerun the simulation with different temperatures if needed.
     
    The plastic deformation generates heat while heat flows from the workpiece to the environment and into the dies.
