【摘要】 研究金属针布专用合金钢丝拉拔变形后,球化退火工艺对碳化物形态及分布状态、拉拔变形量对球化退火组织的影响。结果显示:随着拉拔量的增加,其球化效果越来越好,球粒状碳化物的均匀性和圆整度有了明显改善;较大拉拔塑性变形后钢丝进行球化退火,其退火效果变化不明显,球状碳化物的均匀性和圆整度已经稳定。更多还原

【Abstract】 To research the effects of spheroidization process on carbide configuration and distribution and the effects of drawing deformation magnitude on spheroidization annealing microstructure about special alloy steel wire for metal card clothing after drawing deformation.The results show that the spheroidization effect is better and better with the increasing of drawing deformation magnitude,the uniformity and roundness of spherical carbide are improved obviously;the annealing effect is not obvious after larger deformation to spheroidize steel wire,for the uniformity and roundness have been stable.更多还原
