1.1本试验方法涵盖材料显微压痕硬度的测定、显微压痕硬度试验机的验证和标准试块的校准。 1.2本试验方法涵盖在9.8范围内的试验力下使用努氏和维氏压头进行的微压痕试验 × 10 -3 至9.8 N（1至1000 gf）。 1.3本试验方法包括分析微压痕试验期间可能出现的误差来源，以及这些因素如何影响试验结果的准确性、重复性和再现性。 笔记 1-虽然E04委员会主要关注金属，但所述测试程序适用于其他材料。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 硬度测试对于材料评估、制造过程的质量控制以及研发工作非常有用。硬度虽然本质上是经验性的，但可以与许多金属的抗拉强度相关，并且是耐磨性和延展性的指标。 显微压痕测试将硬度测试扩展到对于宏观压痕测试而言太薄或太小的材料。 显微压痕测试允许特定相或成分以及区域或梯度太小，无法评估宏观压痕测试。 由于显微压痕硬度将揭示材料中可能存在的硬度变化，单个测试值可能无法代表整体硬度。

1.1 This test method covers determination of the microindentation hardness of materials, the verification of microindentation hardness testing machines, and the calibration of standardized test blocks. 1.2 This test method covers microindentation tests made with Knoop and Vickers indenters under test forces in the range from 9.8 × 10 -3 to 9.8 N ( 1 to 1000 gf ). 1.3 This test method includes an analysis of the possible sources of errors that can occur during microindentation testing and how these factors affect the accuracy, repeatability, and reproducibility of test results. Note 1—While Committee E04 is primarily concerned with metals, the test procedures described are applicable to other materials. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== Hardness tests have been found to be very useful for materials evaluation, quality control of manufacturing processes and research and development efforts. Hardness, although empirical in nature, can be correlated to tensile strength for many metals, and is an indicator of wear resistance and ductility. Microindentation tests extend hardness testing to materials too thin or too small for macroindentation tests. Microindentation tests allow specific phases or constituents and regions or gradients too small for macroindentation testing to be evaluated. Because the microindentation hardness will reveal hardness variations that may exist within a material, a single test value may not be representative of the bulk hardness.
