摘要

本文介绍了一种新的组合工艺的研究成果,该工艺涉及多循环拉丝和每个变形阶段后的低温冷却。在理论研究方面,使用 Deform 软件进行了建模。对所有模型中的温度场和马氏体成分进行的分析表明,对于所考虑的两种厚度,最有效的方案是采用低变形速度和不加热工艺。最不有效的方案是在增加变形速度的情况下增加工件厚度,并在不加热至环境温度的情况下进行加工,这将随着工件厚度的增加而对工件轴向区域进行局部冷却。对这种组合工艺的实验室研究分析表明,在变形周期之间不对金属丝进行中间加热的情况下,结构中会形成 100% 的马氏体。但是,如果在变形周期之间将金属丝加热到 20 °C,则可获得马氏体的梯度分布。而且,由于线材具有圆形横截面,在所有情况下,马氏体都以工件中心为轴对称分布。

Symmetrical Martensite Distribution in Wire Using Cryogenic Cooling
This article presents the results of research on a new combined process involving multi-cycle wire-drawing and subsequent cryogenic cooling after each deformation stage. For theoretical research, modeling in the Deform software was performed. The analysis of temperature fields and the martensitic component in all models showed that for both considered thicknesses, the most effective option is a low deformation velocity and the conduct of a process without heating. The least effective option is to use an increased thickness of the workpiece at an increased deformation velocity and the conduct of a process without of heating to ambient temperature, which acts as a local cooling of the axial zone of the workpiece with an increase in the workpiece thickness. An analysis of laboratory studies on this combined process revealed that in the absence of intermediate heating of a wire between deformation cycles, 100% martensite is formed in the structure. However, if intermediate heating to 20 °C between deformation cycles is carried out, a gradient distribution of martensite can be obtained. And, since the wire has a circular cross-section, in all cases, martensite is distributed symmetrically about the center of the workpiece.
