Introduction

Restrictions optical microscope resolving power by conventional hardness test methods can not extend to the nanometer scale, based on the depth of measuring instruments Of the nanoindentation technique emerged. The technology in terms of scale, the principles and parameters measured have undergone significant changes, mainly reflected in. --- With real-time measurement and depth of the press-fit load replace residual indentation diagonal measurement of nano-scale to achieve a measure of operating and Automation process; --- Mechanics by establishing an appropriate model, you can get a variety of hardness and material parameters, such as pressed into modulus; --- Can study the mechanical response of materials throughout the loading and unloading process. In recent years, the rapid domestic nano-indentation test technology development, is becoming the most important means of nanomechanical characterization test field. However And, using this technology affect the test, vulnerable equipment, environment, methods, sample and test personnel, and many other factors, which often leads to results Comparability difference. Therefore an urgent need to regulate the instruments through standardized nano indentation test methods. In 2002, ISO 14577-1.2002 "instrument metal hardness and materials parameters indentation test - Part 1. Test method Law ", ISO 14577-2.2002" instrument metal hardness and materials parameters indentation test - Part 2. testing machines and school Associate ", ISO 14577-3.2002" instrument metal hardness and materials parameters indentation test - Part 3. Calibration of reference blocks "(English Chinese Version) released. In 2007, ASTME2546-07 "Instrumented indentation test procedures" release. The standard of written reference to the above criteria Applicable sections, taking into account the future development trend of technology, two new appendices. Since the major domestic use nanoindentation instrument into Instrumented indentation test line, therefore, the scope of this standard within the limits of such use of the instrument. Instrumented nanoindentation General test method

1 Scope

This standard specifies the basic method of instrumented nanoindentation test equipment and test capacity requirements, but also provides for instrument calibration And testing, indenter, standard sample requirements, and to determine the method of instrument compliance and indenter area function, and given to determine the hardness and material parameters The required number of data analysis methods and precautions indenter used. This standard applies to test a variety of materials and hardness, modulus film, indentation depth typically ranges from nanometers to be expanded Exhibition to several micrometers.
