This study examines the influence of temperature of sub-zero treatment on the wear behaviour of AISI D2 steel. A series of dry sliding wear studies have been made under constant normal load at varying sliding velocities. Emphasis has been laid to understand the operative modes and mechanisms of wear by the estimation of specific wear rates and detailed characterizations of the worn surfaces, wear...
This study aims to reveal the underlying mechanisms responsible for the enhancement of wear resistance of AISI D2 steel by deep cryogenic treatment (DCT) through in-depth microstructural analyses, and thereby attempt to correlate microstructure with wear behaviour of DCT specimens with reference to that of conventional heat treatment (CHT) and cold treatment (CT). Microstructural characterizations...
Exploration of the benefit of cryotreatment for achieving improvement in wear resistance of die/tool steel is a topic of current research interest. A series of wear tests has been carried out on AISI D2 steel samples subjected to cryotreatment at 77K for different durations. The wear rates at different loads and sliding velocities, morphologies of the worn-out surfaces and the characteristics of the...
