由瑞士研究出来的能够测定金属材料硬度的一种最新方法是基于打击被测物的打击物之能量变化的(即测定打击物体前后速度的变化亦即动能之变化,译者注)原理所提出的。由于该仪器应用十分简单且测量范围明显扩大而出类拔萃。其测量范围兼容其它彼此相当的静力学硬度测量方法的所有范围(80—440布氏硬 One of the most recent methods developed by Switzerland for measuring the hardness of metallic materials is based on the principle that the change in the energy of the striker striking the object to be measured (that is, the change in the velocity of the striking object, ie, the kinetic energy) of. The instrument is distinguished by its simplicity of use and its clear measurement range. Its measuring range is compatible with all other static-strength measurements that are comparable to each other (80-440 Brinell
