ABSTRACT The role of chromium in high density Fe–P binary, Fe–P–Cr ternary alloys is observed by
characterization in terms of microstructure, porosity content/densification, hardness and tensile
properties. The alloys were made using a hot powder forging technique. In this process mild
steel encapsulated powders were hot forged into slabs, hot rolled and annealed to relieve the
residual stresses. Densifications as high as 98.9% of theoretical density have been realized.
Microstructures of these alloys consist of single-phase ferrite only. Fe–0.35P, Fe–0.35P–2Cr
alloys showed very high ductility. As forged and hot rolled Fe–0.35P alloy showed very high
elongation and it improved further on annealing. It was observed in this present investigation
that, the alloying addition, such as Cr to Fe–P based alloys caused increase in strength
associated with the reduction in ductility. Alloys developed in the present investigation were
capable of hot/cold working to very thin gage of sheets and wires.
