| 摘 要： | 研究了不同正火加热温度下钒对车轮钢强韧性的影响.结果表明,当加热温度较低时,在强度与无V钢相同的情况下,加钒可显著提高车轮钢的低温冲击韧性;当加热温度较高时,在韧性与无V钢相同的情况下,加钒可显著提高车轮钢的强度.含V车轮钢存在一个适中的加热温度,可获得较好的强韧性匹配.含V车轮钢力学性能的变化规律与V(C,N)的溶解与析出行为有关.

| Abstract: | The effect of vanadium on the strength and toughness of wheel steel normalized at different temperatures were studied.The result shows that compared with V-free wheel steel normalized at lower temperature,Vbearing steel has higher low-temperature impact toughness and almost the same strength.After normalization at higher temperature,V-bearing steel obtains higher strength and almost the same toughness.Therefore,for V-bearing wheel steel normalized at suitable temperature,the strength and toughness can be well improved.The rule mentioned(above) is related with the dissolution and precipitation of V(C,N) in the V-bearing steel. |
