【摘要】 通过金相、电子探针观察和单向拉伸试验 ,对不同终轧压下量的 0 9CuPTiRE钢板的金相组织、夹杂物和力学性能进行了研究。结果表明 :在一定范围内 ,随着终轧压下量的增大 ,钢板组织的晶粒状态变化不大 ,夹杂物总体平均尺寸减小 ,低温横向冲击韧性得到一定程度的改善。更多还原

【Abstract】 The microstructure, inclusion morphology and mechanical property of 09CuPTiRE steel plate after different finishing rolling deformation were studied by the metallographic microscope, electronic probe and one-way tensile test;the result shows that the crystalline grain is not changed much with increase of finishing rolling deformation in certain range, but the overall average size of the inclusions in steel plate is reduced.Meantime,the low temperature transverse impact toughness of the steel is improved to a certain degree.更多还原
