摘要
本文研究了 GCr1 5钢在短时上贝氏体处理下的组织和力学性能 .结果表明 ,在短时上贝氏体等温条件下 ,B上 优先于晶界处析出且具有小针状形态 ,赋予组织较高的强韧性 .
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.
