Abstract

The plastic deformation zone sizes in various metallic materials (steel, copper, armco-iron) are studied during tests by scratching with a tetrahedral Vickers pyramid under the scratch formation conditions at a constant depth. The ratio of the plastic deformation zone depth under a scratch to the scratch depth is found to weakly depend on the scratch depth and to be 6.3–8.5 for the materials under study. Based on these results, we concluded that, when the mechanical properties of a metallic material are determined by scratching, the ratio of the material thickness to the scratch depth should be at least 8.5.

材料的压头划痕测试期间的塑性变形区大小

摘要

在试验过程中，通过在恒定的深度下在划痕形成条件下用四面维氏金字塔进行划痕，研究了各种金属材料（钢，铜，armco-iron）中塑性变形区的大小。发现在划痕下的塑性变形区深度与划痕深度的比值在很大程度上取决于划痕深度，对于所研究的材料，该比率为6.3–8.5。根据这些结果，我们得出结论，当通过刮擦确定金属材料的机械性能时，材料厚度与刮擦深度的比率应至少为8.5。
