Narayanasamy, V. Senthilkumar, K. Pandey] An experimental research work was performed for the understanding of the workability behavior of pure iron preforms produced through powder metallurgy route during hot forging under triaxial stress state condition. Relationship was established between the formability stress index and the axial strain. A relationship between the relative density and the axial strain was also established. Various stress ratio parameter under triaxial stress state condition which indicates the workability behavior of the material namely, $${(\sigma _{\theta }/\sigma _{\rm eff})}$$ , $${(\sigma _{\rm m}/\sigma_{\rm eff})}$$ and $${(\sigma _{z}/\sigma_{\rm eff})}$$ were studied. An attempt has also been made to relate the stress ratio parameters with the relative density (R).
