Wear and Friction Behavior of Multi and Uniaxial Compressed AISI1010 Steel

Deformation processing is an important technique to produce improved and high strength steel products. Uniaxial compression (UAC) imparts high strength and hardness to processed material. On the other hand, multi axial compression (MAC), a type of severe plastic deformation (SPD) technique which is used to develop finer substructure/grains with increased strain. In the present work, two different techniques, warm MAC and warm UAC are used for processing of low plain carbon steel (AISI1010). Mechanical and tribological properties of processed and annealed steel are studied at room temperature and correlated with microstructural changes. Results reveal that hardness and tensile strength of processed steel using MAC and UAC techniques improved significantly as compared to annealed samples; however a reduction in wear resistance is observed which may be attributed to increased brittleness and lower pull-off work resulting in more wear loss due to third body abrasion wear. Fractured and worn surfaces were also studied under scanning electron microscope to understand the type of failure and wear mechanism involved.
