通过测能进行金属材料的动态硬度试验要求在试验材料上留下试验物体的冲击压痕。测量试验物体回弹后存在的剩余能量作为材料硬度的度量。完整的试验过程分三个阶段:打击、冲击和回弹。在打击阶段,试验物体以自由落体方式或用弹簧机构将其位能转换成功能,并以特定的 Dynamic hardness testing of metallic materials by measurement requires the imposition of impact impressions of the test object on the test material. The residual energy present after the test object rebounds is measured as a measure of the material’s hardness. The complete testing process is divided into three phases: Strike, Shock and Rebound. In the combat phase, the test object in free-fall or spring mechanism to convert its potential to function, and to a specific
