摘要
根据拉丝过程中渗碳体分解的观点,并通过实验数据,对高碳钢丝发生分层现象进行研究。当钢丝中铁素体的最高碳原子分数超过1%,钢丝就会发生分层;高碳钢丝的渗碳体在因拉拔而温度升高的表层附近及拉丝后的片层间距小的区域更易分解;拉拔加工导致的强度不均匀性增大是发生分层的主要原因。
To research delamination phenomenon of high carbon steel wire on the view of cementite decomposing during wire drawing and through experiment data. Steel wire can delaminate when the highest content of carbon atom fraction in ferrite of steel wire is over 1%. Cementite of high carbon steel wire decomposes easily near surface layer with high temperature because of wire drawing and in the region of small distance between layers after drawing. The increase of strength uneven in the course of drawing is the main cause for delamination.
