Abstract
The article describes the peculiarities of the formation of the geometry of the deformation zones and the structure of samples made of pure-iron in surface plastic deformation (SPD) by a multiradius roller (MR-roller). The SPD MR-roller leads to a complex kinematic introduction of a deforming tool into the surface layer of a blank and the appearance of a deformation hearth of a curvilinear shape. The results of X-ray structural analysis of pure-iron are presented. It is shown that processing of SPD MR-roller with maximum force results in a significant increase in the microdistortion of the crystal grid, which is characteristic of the nanoscale structure.
摘 要 本文介绍了多半径轧辊（MR-roller）在表面塑性变形（SPD）过程中形成变形区几何形状和纯铁样品结构的特殊性。多半径轧辊表面塑性变形（SPD）导致变形工具以复杂的运动方式进入坯料表层，并出现曲线形状的变形炉膛。本文介绍了纯铁的 X 射线结构分析结果。结果表明，以最大力加工 SPD MR-roller 会导致晶体网格的微变形显著增加，这是纳米级结构的特征。
