Influence of Structural Parameters on the Yield Strength of Tempered Bearing Steel with Martensite-Bainite Dual Phase Structure

Xu Zuoren Huang Xingjia  
A study was made of the change of structural parameters andretained austenite as a function of volume fracion of lower bainite decomposedin GCr 15 bearing steel,aftr isothermal quenching and tempering.Mechanicalproperties of martensite-lower bainite dual phase structure were tested.Therelation of the yield strength of martensite in the dual phase structure and theeffective grain size agrees well with the Hall-Petch model while strengthening mechanism about the width of ferrite plates of lower bainite((?)_B)and thelength of dispersion of carbides((?))is controlled both by the Langford-Cohen relationship of sub-structure hardening and Orowan dispersion streng-thening effect.On the contrary,the retained austenite may set disfavoureffect to course the decrement of yield strength.The present investigationattempts to evaluate the magnitude of these individial contributions to thestrength of martensite—lower bainite dual phase structure.An empiricalequation was deduced which agreed well with the experimental results.
