ISO 14577的这一部分规定了用于测定硬度的仪器化压痕试验方法 以下三个范围的硬度和其他材料参数:宏观范围:2 N≤ F≤ 30千牛；微观范围:2N>F；h>0,2µm；纳米范围:h≤ 0.2µm。在纳米范围内，机械变形强烈取决于压头尖端的真实形状和压头直径 压头的接触面积函数对计算的材料参数有显著影响 用于试验机。因此，需要仔细校准仪器和压头形状 为了达到可接受的材料再现性，需要使用 不同的机器。宏观和微观范围通过与压痕深度相关的试验力来区分。需要注意的是，微观范围有一个上限，由试验力（2N）和 压痕深度的下限为0.2µm。硬度和其他材料参数的测定见附录A。 在高接触压力下，压头可能损坏。因此，在宏观范围内， 通常使用硬质合金压头。对于硬度和弹性模量非常高的试样， 压头可能发生永久变形，并可使用合适的参考材料进行检测。它是 必须考虑其对试验结果的影响。本试验方法也适用于薄金属和非金属涂层以及非金属涂层 材料。在这种情况下，建议考虑相关标准中的规范 账户（另见6.3和ISO 14577-4）。交叉引用:ISO 14577-2:2015ISO/IEC指南98-3:2008ISO 4287ISO 14577-3:2015ISO 14577-4购买本文件时提供的所有当前修订版均包含在购买本文件中。

This part of ISO 14577 specifies the method of instrumented indentation test for determination of hardness and other materials parameters for the following three ranges:macro range: 2 N ≤ F ≤ 30 kN;micro range: 2 N > F; h > 0,2 µm;nano range: h ≤ 0,2 µm.For the nano range, the mechanical deformation strongly depends on the real shape of indenter tip and the calculated material parameters are significantly influenced by the contact area function of the indenter used in the testing machine. Therefore, careful calibration of both instrument and indenter shape is required in order to achieve an acceptable reproducibility of the materials parameters determined with different machines.The macro and micro ranges are distinguished by the test forces in relation to the indentation depth.Attention is drawn to the fact that the micro range has an upper limit given by the test force (2 N) and a lower limit given by the indentation depth of 0,2 µm.The determination of hardness and other material parameters is given in Annex A.At high contact pressures, damage to the indenter is possible. For this reason in the macro range, hardmetal indenters are often used. For test pieces with very high hardness and modulus of elasticity, permanent indenter deformation can occur and can be detected using suitable reference materials. It is necessary that its influence on the test result be taken into account.This test method can also be applied to thin metallic and non-metallic coatings and non-metallic materials. In this case, it is recommended that the specifications in the relevant standards be taken into account (see also 6.3 and ISO 14577-4).Cross References:ISO 14577-2:2015ISO/IEC Guide 98-3:2008ISO 4287ISO 14577-3:2015ISO 14577-4All current amendments available at time of purchase are included with the purchase of this document.
