AFM, SPM & SEM Testing with MTI Instruments SEMtester

AFM, SPM & SEM Testing with MTI Instruments SEMtester

MTII/Fullam provides a unique, compact test system specifically designed to fit inside scanning electron microscopes.

These new systems are capable of carrying out fatigue, compression, bending and tensile testing, making them ideal testers for material scientists and researchers. Grain rotation, crack propagation, and various other tests of mechanical stress can be observed during testing under high magnification in an electron microscope.

This provides greater insight into the early stages of material failure and an enhanced overall understanding on the performance of particular materials. MTII/Fullam uses the MTESTQuattro™ material testing system from ADMET Inc. in order to control experiments and collect data.

A user-friendly interface to set system test parameters and analyze data is provided by this powerful package. During the testing stage, results are provided in real time and stress-strain curves are generated. Significant parameters such as modulus of elasticity, offset yield, peak load/stress and other measurements are also reported.

It is also possible to export raw test data and results in standard formats, making it easy to integrate with other data analysis and laboratory management systems.

MTII/Fullam provides a variety of custom clamps for almost all shapes of materials. Quick connect mounting fixtures are also available for flawless integration into most major microscopy tools. Users are able to install systems without modification to vacuum chambers or microscopes with the help of post covers and adapters.

Precision Measurement and Material Testing Solutions

Advanced LM, SPM, and SEM Material Tensile Testing Systems obtain accurate, fast and reliable information about the mechanical properties of materials with MTII/Fullam’s SEMtester series of tensile and compression testers.

These miniature tensile testers have been specifically designed for use in Light Microscopes (LMs), Scanning Probe Microscopes (SPMs) and Scanning Electron Microscopes (SEMs), and are ideal for performing experiments under magnification.

This provides greater insight into the initial stages of material failure and a much improved understanding of the performance of specific materials. Additionally, it is also possible to observe crack propagation and grain dislocation in real time, revealing more details about deformation than standard, post-failure analysis techniques.

Flexible Design

MTII/Fullam offers a wide range of fully automated, semi-automated and manual platforms for any budget. Load frame capacities of 2000 lb (9000 N), 1000 lb (4500 N), and 100 lb (450 N) are standard with selectable load cells to enhance sensitivity and accuracy, and also to match customer requirements.

Extended strain travel versions are available enabling longer, more ductile samples to be tested. The flexibility to operate with typical microscopes and EBSDs is provided by both angled and horizontal specimen clamps. Quick-connect mounting adapters are provided and designed for perfect integration into most major microscopy tools. Customized port covers allow users to install systems without modifications to microscope platforms or vacuum chambers.

Intuitive Operating Package

MTII/Fullam uses a proprietary Windows®-based control and material testing software system that complies with ASTM specifications in order to monitor experiments and collect data. A user-friendly interface to set system test parameters and analyze data is provided by this powerful package.

Specimen dimensions are defined together with strain rates and thresholds (time, elongation, load), which are then used to perform automated tests and calculations. These parameters are stored as “recipes” that can be called upon again for future experiments.

During testing, results are provided in real time and stress-strain curves are generated. Vital parameters such as modulus of elasticity, offset yield, peak load/stress and other measurements are reported. It is possible to export raw test data and results in standard formats, resulting in effortless integration with other data analysis and laboratory management systems.

Applications

The SEMtester line of products is capable of performing compression, bending, tensile, creep and fatigue testing on a wide range of materials. Deformation and relaxation behavior can be monitored under static or dynamic loading. Optional thermoelectric heaters/coolers or sample heaters can be used during testing to simulate actual operating conditions.

A range of specimen clamps are available to accept almost any sample configuration. This versatility makes the SEMtester product line ideal for testing a variety of materials:

  • Minerals
  • Composites
  • Plastics
  • Metals
  • Foods
  • Textiles
  • Polymers
  • Hairs
  • Fibers
