Formability and strain hardening are significant phenomena that are necessary to understand the plastic deformation phase of any material. They are also a key factor in understanding the workability requirements for metals. This study was done to evaluate the strain hardening as well as formability phenomenon that happens when sintered aluminum-nano iron powder composites are cold worked. Formability index increases quickly during the initial stage of deformation, followed by a slow rise when real axial strain grows further. Furthermore, it has been discovered that higher iron addition results in higher values of formability index. Also, the coefficients of rapid density Bi & Ci of the proposed aluminium ferrous composite preforms were being investigated and assessed analytically.
