摘要/Abstract

摘要： 设计并冶炼了钒质量分数为0%~0.13%的高碳钢,采用光学显微镜、扫描电镜、电子背散射及拉伸试验等研究了钒含量对高碳珠光体钢组织及拉伸性能的影响。结果表明,钒可以提高组织均匀性及铁素体含量,并且减小晶粒尺寸,但钒含量超过0.08%时,晶粒细化作用减弱。钒质量分数为0%~0.13%时,珠光体片层间距与强度的关系紧密,并获得了相应关系式。试验钢塑性对钒含量并不敏感,钒含量不超过0.08%时,略微提高塑性,反之,则降低塑性。

Abstract: The high carbon steel with vanadium mass fraction of 0%-0.13% was designed and smelted. The effect of vanadium content on the structure and tensile properties of high carbon pearlite steel was studied by means of metallographic microscope, scanning electron microscope, electron backscattering and tensile test. The results show that vanadium can improve the structure uniformity and increase ferrite content, and reduce the grain size, but when the vanadium content exceeds 0.08%, the grain refinement effect is weakened. When the mass fraction of vanadium is 0%-0.13%, the relationship between the pearlite lamellar spacing and strength is close, and the corresponding relationship is obtained. The plasticity of the tested steel is not sensitive to the vanadium content. When the vanadium content does not exceed 0.08%, the plasticity is slightly increased, otherwise, the plasticity is reduced.

Key words: vanadium content, high carbon steel, microstructure, strength, plasticity
