Elimination and Control of δ Ferrite in M50NiL Bearing Steel
Advances in Materials Science and Engineering, 2022 In this study, the effects of the annealing temperature and holding time on the δ ferrite content in M50NiL bearing steel are evaluated. The results indicate that when the temperature increases from 900°C to 1200°C, the δ ferrite content increases as a ...
