Abstract
In this paper influence of load on change in weight loss (mg), hardness and wear transition of 0.12 wt.% Al-Mn-steel (Steel A), 0.35 wt.% Al-Mn-steel (Steel B) and Mn-steel (Steel C) has been examined. With the increase in load these steels shows remarkable decrease in weight loss due to change in surface microstructure from austenite to e or ά - martensite which results in increase in hardness of material. With the increase in hardness transition in wear mechanism has been noticed. In future aspect these steel would prove to be better material as wear resistant liner in many industrial application.
Highlights
The manganese steel (Mn-steel) material was derived from the investigation done by Robert Hadfield’s in 18821
This paper aims to find out the tribological effect of Al addition in Mn-steel alloy and selection of better material which can be used in future as wear resistant material
The chemical compositions of material were determined from energy dispersive X-ray analysis (EDX) as attached with FE-SEM ZEISS Supra 55(Germany) with air lock chamber mainly used in scientific research
Summary
The manganese steel (Mn-steel) material was derived from the investigation done by Robert Hadfield’s in 18821 It shows great interest in many mechanical and mining engineering sectors. It has an exceptional features like resistant to corrosion, low density, high strain hardening, high strength and better elongation which attracts the industries to use it as wear resistant material. It is called as austenitic steel as its manganese (Mn) content is at austenitic phase. The mechanical property of Mn-steel material is based on the theories of dipole interaction (DI) and stacking fault energy (SFE)[2].
