在线贝氏体线材的开发

Development of on-line Bainite Wires

线材轧制后采取直接熔盐热处理,在恒温状态下生产出以上贝氏体为主体的高碳钢线材。上贝氏体组织由于渗碳体分散、对位错的移动阻碍性小,而具有高的延性和拉丝加工性能。

Direct isothermal heat treatment in the salt bath after wire rod rolling,upper bainite microstructure is man ufactured.As the cementite dislocation moves smoothly during deformation leading to high ductility and drawavility.
