在科学研究中很少应用压痕硬度(IndentationHardness),因为其具有复杂应力状态且不能用单项数量来表示。此外,通常硬度值与机械性能和原子性能等有一定关系;如与屈伏点、抗拉强度、疲劳强度、蠕变、持久强度、晶体结构、压缩率、离子直径、李德曼频率等等。这种硬度与某些电子和磁性性能也有关并可用简单而灵敏的方法去研究时效硬化、应变时效、回复和再结晶、相变与等温相变等。
Indentation Hardness is rarely used in scientific research because of its complex stress state and can not be expressed in a single number. In addition, the hardness value is usually related to the mechanical properties and atomic properties, such as the bending point, tensile strength, fatigue strength, creep, long-lasting strength, crystal structure, compressibility, ionic diameter, the Lyman frequency and so on. This hardness is also related to certain electronic and magnetic properties and can be used to study age hardening, strain aging, recovery and recrystallization, phase transformation and isothermal transformation in a simple and sensitive way.
