在材料机械性能测试中,硬度测量是一种最迅速、最经济的测试方法。它不毁坏工件,也不限于重点抽试。硬度值与其它机械性能之间有着比较精确的对应关系,这就决定了硬度试验的实际意义和它在材料性能测试中所占的地位。目前,这一简单的机械试验已广泛地用于试验室和工厂车间。但是,也应该看到,硬度测量也是一种在理论上还未被很好认识的测试方法,许多问题正有待 In the mechanical properties of materials testing, hardness measurement is one of the most rapid and most economical test method. It does not destroy the workpiece, nor is it limited to focus on the test. Hardness values ​​and other mechanical properties have a more precise correspondence between, which determines the practical significance of the hardness test and its position in the material properties test. At present, this simple mechanical test has been widely used in laboratories and factory floor. However, it should also be observed that hardness measurement is also a test method that has not been well understood in theory, and many problems are waiting for
