| 摘 要： | 研究了S含量对高速车轮钢断裂韧性的影响.结果显示,适当提高车轮钢中的S含量,可以有效提高断裂韧性.对夹杂物的分析表明,S含量为0.001％(质量分数)的车轮钢中Al2O3和Al2O3+(Ca,Mg)O的氧化物夹杂相对较多,而MnS夹杂物较少.在相近的O含量水平下,将S含量从0.001％提高到0.006％,车轮钢中夹杂物...

| Abstract: | The effect of sulfur contents on fracture toughness of railway wheel steels for high speed train was investigated.The results show that,with the same production process,sulfur content increase to some extent in wheel steels resulted in a great improvement in fracture toughness.The analysis of non-metallic inclusions revealed that,in the steel with sulfur content of 0.001%,a large amount of Al_2O_3 and complex Al_2O_3+(Ca,Mg)O inclusions were found,while MnS inclusions were rarely observed.When S content was... |
