Current trends towards ‘downsizing’ of rolling bearings result in higher demands on the product properties with respect to higher load carrying capacity and resistance to rolling contact fatigue. The objective to further improve the product performance is a challenge, especially considering the high quality standard of modern bearing steels. Heat treatment and specifically quenching are important for producing the desired product properties and therefore further development of these processes is considered relevant for future generation products. To minimize the amount of testing, computer simulations of the effects from heat treatment processes on the resulting product properties are increasingly used as a development tool. This presentation describes work performed to simulate two different quenching cycles, quenching in oil and quenching in salt, applied during through hardening treatments of SAE 52100 bearing steel, in order to understand and predict the hardening process with respect to phase transformations and residual stress generation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
