Hardness testing method

The invention relates to a hardness testing method. The hardness testing method comprises the following steps of: (1) impacting the surface of a to-be-tested sample by using an impact body with kinetic energy E, enabling the impact direction of the impact body to be perpendicular to the surface of the sample, and leaving an impact indentation on the surface of the to-be-tested sample; (2) measuring the size of the impact indentation in the step (1), and calculating the surface area S of the impact indentation; and (3) calculating a hardness value H of the to-be-tested sample according to a calculation formula shown in description. The operability, applicability and testing efficiency of the hardness testing method are improved, and the hardness testing method is efficient, good in repeatability and applicable to hardness measurement of large thin-walled samples. 本发明涉及一种硬度的测试方法。包括以下步骤：(1)用具有动能E的冲击体冲击待测试样的表面，冲击体的冲击方向与试样表面垂直，在待测试样的表面留下冲击压痕；(2)测定步骤(1)所述冲击压痕的尺寸，计算冲击压痕的表面积S。(3)计算待测试样的硬度值H，计算公式为本发明方法提高了测试方法的可操作性、适用性
