Abstract : This technical paper deals with high temperature dry sliding wear behavior and its mechanism of Inconel 718 and Hastelloy X alloys. The sliding wear behavior of the Inconel 718 alloy and Hastelloy X was investigated using a pin on disc equipment at 500°C with varying normal load. Hastelloy X has shown the higher coefficient of friction in comparision to IN718. SEM features of worn samples reveal that delamination, ploughing and deep grooving are the dominant wear mechanisms for IN718, while for Hastelloy X, it is shear band, cleavage formation, debris generation.
