| Abstract: | In this paper,the microstructure and mechanical properties of upper bainite in GCr15 steel are studied.The result reveals that at the early stage of isothermal treatment in the region of upper bainite,the nuclei of upper bainite,with needle like morphology,appears originally at the boundary of austenite,gives the structure higher toughness and strength. |
