Abstract

Densification behaviour of sintered Fe-0.8%C-1%Si-0.8%Cu powder metallurgy steel under the influence of two different aspect ratios subject to cold forging is studied in the present investigation. The critical evaluation of cold deformation exercise revealed that induced strains are linearly contributing to enhance densification till the specimen fracture; however overall resistance to deformation of material is exhibiting in three different responses with respect to improvement in densification. That is at initially, high resistance to deformation followed by high kinetics of deformation and finally exhibiting little resistance against overall deformation. Although, the aforementioned criteria is common for both the aspect ratios, the applied deformation is little homogeneous when aspect ratio is less that directly contributes to enhance the rate of attainment of densification as little faster in the later stage of densification on the other hand the higher aspect ratio preform is bit non-linear in nature and retards stress in the later stage.
