摘要: 研究了冷拉钢丝的变形及对强化的影响,结果表明:冷拉钢丝中的渗碳体片已成为易变形的塑性相,在Fe_3C/F界面上有许多“坎”(Ledge)存在,可发射位错,这可能是变形时造成Fe_3C/F界面有较高的位错密度原因之一;证实了位错可切过渗碳体片,必须考虑这一因素对强化的贡献。

关键词 ：冷拉钢丝, 位错胞, 坎

Abstract：During cold-drawing of plain steel wires, the fine lamellar cementitealtered into a ductile phase with feasible deformability. A lot of ledges, which mayemit the dislocations, are found along the Fe_3C/Fe interface. This seems to be oneof the causes for formation of greater dislocation density along the Fe_3C/Fe inter-face during deformation. There was enough evidence to prove that the dislocationcut through Fe_3C. Therefore, it is necessary to consider its effect on strengthening.

Key words： deformation strengthening cold-drawn steel wire dislocation cell ledge cementite
