Small-Scale Mechanical Testing in the Scanning Electron Microscope

In-situ small scale mechanical testing has gained popularity over the last decade due to improvements in SEM platforms along with the development of small-format mechanical testing instrumentation suitable for the microscope chamber. The coupling of these two techniques allows researchers to precisely probe the sample surface while observing material deformation in real-time. This webinar discusses the wide variety of small-scale mechanical testing techniques that are possible inside the SEM.

Small Scale Mechanical Testing in the SEM Webinar

Cold and Colder, Nanoindentation Down to -120°C

Materials behavior is often dominated by highly localized phenomena, and the ability to probe these local properties for engineering devices is critical. Often these devices are operating in environments with large differences in temperature and pressure: from the high vacuum and cold of space to the high temperature and high pressure inside a deep-water oil well. This webinar focuses on testing from room temperature down to -100°C on a variety of materials classes.

Nanoscale Tribology: Understanding Mechanical and Tribological Surface Modification in Lubricated Contacts

Tribological properties play a critical role in the proper function, longevity, and energy efficiency of mechanical systems. The ability to quantitatively characterize surface interactions over the nanoscale and microscale provides a new understanding of how to better control friction and wear behavior in bulk material systems and thin tribological films.

In this webinar we discuss the theory and applications of tribological and mechanical characterization over the nanometer to micrometer length scales. Practical applications are presented relating to the field of lubricated sliding materials found in pistons, bearings, rubber gaskets, and other interacting components used in engines and power trains. We demonstrate how nanoscale indentation and scratch testing provides powerful information for studying localized changes due to tribological processes.


Dynamic Nanoindentation Characterization - nanoDMA III

Bruker’s nanoDMA® III testing mode substantially increases the characterization capabilities throughout the Hysitron nanoindentation product family. nanoDMA III is an indentation-based dynamic mechanical analysis technique that superimposes a small force oscillation over a static load to deliver quantitative and repeatable mechanical characterization over the nanometer-to-micrometer length scales. This webinar discusses nanomechanical properties of elastic-plastic and viscoelastic materials and the influence of environmental conditions such as temperature & humidity. We will explore the material response to stress (creep & relaxation) and to an oscillating indenter probe at changing frequencies. Additionally, we will review possibilities to quantitatively map the elastic modulus of surfaces.

In this webinar, we provide a brief overview of quasi-static and dynamic nanoindentation, dynamic nanoindentation measurement theory and best practices, the applications of: depth profiling of elastic-plastic mechanical properties; viscoelastic characterization—storage modulus, loss modulus, tan-delta; and combined dynamic nanoindentation and environmental control.

XPM: High Speed Nanoindentation and Mechanical Property Mapping

Nanoindentation techniques have long had an important role in quantitatively evaluating the mechanical properties of microstructural features. In recent years, high speed nanoindentation mapping techniques have been under development and have recently achieved speeds up to 6 indents/second, approximately 500x faster than traditional nanoindentation mapping methodologies. This enables a one-to-one correlation with other techniques, such as EBSD, and provides corresponding large data sets for robust statistical analysis. This correlation can produce high resolution structure-property relationships which can be mapped over sub-micron to several hundreds of micron length scales. High speed nanoindentation has numerous potential applications, from evaluation of microstructure-property evolution during processing, quality control testing of weld zones, evaluation of sub-surface damage gradients (wear, corrosion, irradiation), composite material interfaces, and more.


NanoIndentation, Scratch and nanoDMA Innovations for Atomic Force Microscopes

The TriboScope seamlessly interfaces with Atomic Force Microscopes to deliver quantitative and repeatable mechanical and tribological characterization over the nanometer-to-micrometer length scales. By utilizing a rigid test probe, the TriboScope enables static and dynamic instrumented indentation.

This webinar discusses how nanomechanical properties are obtained via AFM-based nanoindentation comparing rigid probe vs cantilever based measurements. We explore true force and displacement feedback control modes and cover applications from soft polymers to hard ceramics. Additionally, we review nano-scratch, nano-wear and nanoDMA techniques and applications.
