The Cr/C ratio and Si must be controlled strictly to produce Cr-V-Ti troostite grinding ball. 生产铬钒钛屈氏体磨球要严格控制 Cr/C 比和元素 Si.
The result proves that the accumulate line is caused by heat treatment defect, soft troostite tape. 结果表明,活塞杆在磁粉探伤中显现的螺旋形磁粉堆积线是由热处理缺陷一屈氏体软带造成的。
Marensite and mixed matrix structure,which is composed by sorbite,troostite and small amount of banite,were found in the experiment. 实验结果表明:马氏体的出现及基体为索氏体、屈氏体和少量的贝氏体的混合组织是断裂的主要原因;
Marensite and mixed matrix structure, which is composed by sorbite, troostite and small amount of banite, were found in the experiment. 实验结果表明：马氏体的出现及基体为索氏体、屈氏体和少量的贝氏体的混合组织是断裂的主要原因；
The technology not only guarantees that there are good microstructures of the tempered troostite and sorbite in the wire rod steel, but also makes environmental pollu. 该工艺在保证盘条钢具有良好的回火屈氏体和索氏体组织外,还减少了对环境的污染和对人体的危害。
The mechanical properties testing, microstructure observation and fractographic features analysis of the troostite high chromium cast iron blade were carried out. 对屈氏体高铬铸铁叶片进行力学性能测试、显微组织观察和断口形貌分析。
