Continuous Stiffness Measurement
Continuous Stiffness Measurement
In conventional quasi-static indentation testing, the stiffness of contact is determined by analyzing the force vs. displacement curve during unloading. This depth-sensing method provides a single measurement for the given indentation depth. The KLA-Tencor Nano Indenter G200 Continuous Stiffness Measurement (CSM) mode, which is compatible with both the XP and the DCM II indentation heads, satisfies application requirements that must take into account dynamic effects, such as strain rate and frequency.
The CSM technique is a revolutionary step in the mechanical property measurement of materials. It allows the measurement of depth-dependent properties of materials in a single step. The method involves applying a dynamic load on the top of the static load while loading. The dynamic part of the load is then used to measure the stiffness which is further processed to calculate the modulus and hardness of the material.
The CSM option offers a means of separating the in-phase and out-of-phase components of the load-displacement history. The separation provides an accurate measurement of the location of initial surface contact and continuous measurement of contact stiffness as a function of depth or frequency, thus eliminating the need for unloading cycles. This makes CSM a powerful tool not only for stiff materials such as metals, alloys, and ceramics but also for time-dependent materials like polymers, structural composites, and biomedical materials. The state-of-the-art CSM option provides the only means available to both fully characterize dynamic properties in the nanometer range and accurately characterize viscoelastic materials, providing values such as complex modulus. Indentation tests using CSM can be controlled with a constant strain rate, a critical test parameter for material systems such as pure metals or low-melting-point alloys, and polymer films and film/substrate systems.
Express Test is an option that allows up to 100 indents to be performed at 100 different surface sites in 100 seconds. Express Test, the world’s fastest means of performing instrumented indentation for mechanical-properties mapping at the nanoscale, is compatible with all G200 indentation heads and stages!
Designed exclusively for use with the Nano Indenter G200, KLA-Tencor’s highly versatile, easy-to-use Express Test methods are ideal for applications that involve metals, glasses, ceramics, structural polymers, thin films, and low-k materials. This technique is particularly useful to investigate heterogeneity in the sample surface such as irradiated materials, heat treated materials, and multi-phase alloys when the properties are not constant across the surface.
With KLA-Tencor NanoSuite software, users can automatically generate histograms and 3D mechanical-properties maps. Graphs and supporting data are easily exported to Microsoft Excel.

High Temperature Nanoindentation
High Temperature Nanoindentation
It is difficult to maintain temperature without thermal drifts in a high-temperature experiment. The Laser Heater option for the Nano Indenter G200 system is the solution. It utilizes a precise high-power diode laser to heat the stage and sample to address this issue. Advantages include the ability to measure nanomechanical properties at controlled temperatures and the ability to test samples under dynamic temperature conditions. The system’s laser-heated indenter tip prevents disturbance of substrate temperature during measurement. By keeping the tip and sample at the same temperature, the G200 enables high-temperature continuous stiffness measurements (CSM) with exceptional precision.
The G200 laser heater is the world’s most flexible instrument for high-temperature nanoscale mechanical testing. When time or temperature dependent deformation occurs, it becomes difficult to decouple creep and elastic recovery during the unloading segment of a quasi-static test for the calculation of stiffness. So, as opposed to measuring the stiffness from unloading the material, the CSM technique imposes harmonic displacement oscillation during the hold period at peak indentation force to measure high-temperature properties.
To ensure reliable data, the laser heater option minimizes drift associated with heating. Users have the option to purge samples with various gasses to avoid contamination and oxidation.
- Wide temperature ranges up to 500C
- Ultrafast heating and cooling
- Minimizes thermal drift
- Easy, convenient operation
- Option to purge samples with various gases to avoid contamination and oxidation
- Dynamic measurements enabled by Continuous Stiffness Measurement (CSM) option
