I am also looking for the stress starin curves of related material 51CrMoV4 .....(AISI 4150) ..for details go to my blog :

Flow Stress Curves for 51CrMoV4 material at varying temperature and strain rates

cheers,

Krunal.

Thank you very much for the

Thank you very much for the reference. But 4150 has 10percent lesser reduction in area % and 2 percenl lesser elongation when compared to 4340 and so the material model will definitely change because of this. I am still searching for the material model. So if you come across, the material model somewhere, please let me know. Thank you very much.

With Best Regards

Re: AISI 4150 flow stress data

If 4150 and 4340 have similar compositions you should be able to use the flow stress data from 4340 that you can find on my paper linked to on http://imechanica.org/node/1278.

The flow stresses are similar for many steels even though the strains to failure may be quite different.
