薄带连铸铌微合金化低碳钢的组织与性能吴微1,2,梁高飞3,方园3,于艳3,孙宝德4(1.上海市上海交通大学材料科学与工程学院2.上海市宝钢股份研究院3.宝钢研究院,上海 2019004.上海交通大学 材料与工程学院,上海 200240)摘 要:研究了薄带连铸铌微合金化低碳钢的组织与力学性能,利用电子背散射技术(EBSD)标定了铁素体(贝氏体)的晶粒取向和晶界特征,并利用透射电镜(TEM)观察了铸带及热轧带钢中的析出物.结果表明:薄带连铸铌微合金化低碳钢凝固组织主要为两侧柱状晶区,中间存在一定宽度的等轴晶区.室温......
caused by the lower cooling rate. Therefore,twin-roll casting is not only a method being capable for producing strips with a large thickness, but also prone to obtain a high energy state of the MG strip... and twin-roll casting, respectively. The increase in thickness of either ribbons or strips results in a lower energy state with a smaller relaxation enthalpy, a lower content of free volume, and a higher......
