通过对有色金属材料不同截面形状(圆柱形、平板)的硬度试样进行布氏硬度测试,获得不同压痕形貌及相关形貌特征参数;通过对应平板试样的压痕直径,寻找圆柱形试样压痕硬度特征参数表示方法。结果表明:有色金属圆柱试样布氏硬度压痕特征表现为近似椭圆,通过测定椭圆的长短轴长度,建立圆柱试样椭圆形压痕与平面中圆形压痕的等效关系,从而测得柱面形试样的表面布氏硬度。 The Brinell hardness of different cross-sectional shapes of non-ferrous materials (cylindrical and flat plate) was tested to obtain the different indentation morphology and the related morphological parameters; by looking for the indentation diameter of the flat plate sample, the cylindrical shape Specimen indentation hardness characteristic parameter representation. The results show that the indentation characteristics of Brinell hardness of non-ferrous cylindrical specimens are approximate ellipses. By measuring the length and length of the ellipse, the equivalent relationship between the elliptical indentations of cylindrical specimens and the circular indentations in the plane is established. Surface Brinell hardness of cylindrical specimens.
