introduction
Instrumented nano-indentation test is a micro/nanomechanical test technology developed in the past two decades. The technology has since its birth, has
Disciplines widely used in materials science, physics, biology, mechanics and industrial production is becoming a micro/nanomechanical test technology
One of the important means.
Specification instrumented nanoindentation techniques involved in the terms and their definitions, help to enhance the understanding and communication technology to promote the
Promotion and application of technology, to make it better for scientific research, production and trade in services.
Instrumented nanoindentation test terminology
1 Scope
This standard defines the instrumented nanoindentation test on the basis of universal, instrument characteristics, mechanical measurement, parameter identification, test specimens, test equipment
Fixed aspect involved in common terms and their definitions.
This standard applies to instrumented nanoindentation test can also be widened to instrumented indentation test.
2 Universal base
2.1
Instrumented indentation test instrumentedindentationtest
Drive selected indenter into the specimen, load and automatically measure the applied pressure in the sample depth, calculated based on the mechanical model of the timber
Hardness and mechanical parameters of the test material.
Note 1. Instrumented indentation test focuses on the course of action, similar to the tension, compression, bending, torsion testing; and hardness measurement focuses pushed after unloading residues
Size left indentation, often called indentation.
Note 2. The international standard ISO 14577 and press-fit load F depth h, the test is divided into. a macroscopic scale (macrorange), 2N≤F≤30kN; microstructure
Range (microrange), F <2N, h> 0.2μm; nanometer range (nanorange), h≤0.2μm.
Note 3. The instrument load range is usually no more than 500mN, corresponding indentation depth in nanometers to several micrometers, used to call the nanoindentation
(Nanoindentationtest). At present, we tend to adopt the international standard ISO 14577 naming, multi-called instrumented indentation test.
2.2
Indentor instrumentedindentationtester
Through direct and indirect calibration inspection, it is possible to achieve Instrumented indentation test instruments.
Note 1. The instrument does not belong to the traditional pressed into the hardness category. Traditional durometer hardness only measure, and pressed into the measured hardness tester can not only, but also measuring the elastic modulus
Amount and other mechanical parameters.
Note 2. The instrument is pressed into the material testing machine belonging to the category. Traditional materials testing machine for whole-destructive test specimens, and pressed into the micro-sample instrument for micro-damage
Type test.
2.3
Nanoindentation instrument nanoindentationtester
Indentation depth is usually in the order of a few microns to nanometers, load and displacement measurements are generally superior resolution and 10-1nm amount 101nN
Indentation level meter.
Note 1. Currently, such instruments to electromagnetic or electrostatic driven mainly typical range is 500mN or 10mN.
2.4
Indenter indenter
Indentor for pressed into the specimen and having a specific geometric shape and size of the parts.
Note 1. The head is usually composed of two parts. Often used in front of the diamond, sapphire, tungsten carbide and other materials, ground into a fine tip required predetermined geometric
Shape and size, for pressing into the sample; rear often used steel materials, processed into a predetermined shape of the base plate for fixing the front head portion and the connecting device
Control lever.
Note 2. Factors nanoindentation test results, compression tip of geometry deviation from the shape of its design, as well as determining the shape of the error, etc.
influences.
Note 3. The actual use, usually based on the design of the indenter tip geometry classification, including Vickers indenter, Bolivia's head, cube corner indenter, and conical indenter
Spherical pressure class.
