Abstract

A brief overview is presented for means of severe plastic deformation during the formation of gradient structure from the viewpoint of physical mesomechanics. An analysis of the results on the impact of the means of drawing with shear on steel; severe plastic deformation by high pressure torsion on steel, titanium, and copper; and alternating bending by applying a ECAP-Conform stand on copper. It is shown that structures with different degrees of gradient form in the materials as a result of these actions.

严重塑性变形在金属中产生梯度结构

摘要

从物理细观力学的角度简要介绍了梯度结构形成过程中严重塑性变形的方法。分析结果对剪切方式对钢的影响；钢，钛和铜上的高压扭力会导致严重的塑性变形；并通过在铜上施加符合ECAP的支架来交替弯曲。结果表明，这些作用在材料中形成了不同梯度度的结构。
