Finite Element Wear Behaviour Modeling of Super duplex stainless steel AISI 2507 Using Ansys

Abstract

In this paper the finite element simulation approach has been employed for the work that has been recently carried out by Davanageri et al.(2017). The super duplex stainless steel AISI 2507 material was heat treated at 850�C with different ageing time (30, 60, 90 minutes), followed by water quench. The heat treatment was carried out to encourage the precipitation of inter-metallic secondary sigma phase (?). The study of dry sliding wear behavior was carried out with the pin-on-disc equipment. The heat treatment and ageing time increases the hardness of the duplex steel, resulting in improved wear resistance. The Archard wear model and finite element software ANSYS WORKBENCH-16 was used to determine the wear volume loss. The specific wear rate or dimensional wear coefficient is the most significant factor in the wear volume calculation and it varies with material and operating parameters. The study shows that frictional coefficient varies with material properties (hardness) at similar operating condition. Finally the results reveal that there is a good agreement that exists between the simulated (FE) values and those of the experimental values. � Published under licence by IOP Publishing Ltd.
