Quantitative Nanoindentation and Nanotribology of Metals

High performance metals development depends on the ability to enhance mechanical and tribological properties through proper alloy design and phase/microstructure control.  Depending on the atomic species present, relative atomic concentrations, atomic mixing, and phase transitions during the solidification process, metal alloys can exhibit a very broad range of mechanical and tribological properties. The complexity of modern day alloy design combined with the size of microstructural elements requires highly localized measurement techniques to understand and tailor bulk mechanical behavior.

Nanoindentation of Metals

Nanoindentation, or instrumented indentation, is a rapid means of characterizing the mechanical properties of complex metallic microstructures. Nanoindentation is a combined technique that can extract quantitative modulus and hardness information from a single indentation measurement. Hysitron’s instruments have nanometer-precision test placement accuracy, allowing nanoindentation measurements to be placed on individual phases/grains of metal, quantitatively map surface mechanical properties and property gradients, measure interfacial properties between phases, and explore anisotropic properties.

Nanotribology of Metals

Hysitron’s nanotribological test equipment utilize dimensionally rigid scratch probes to investigate single asperity contact and better understand fundamental tribological properties of metallic surfaces. Hysitron’s ultra-sensitive transducer technology and test positioning accuracy allows for detailed characterization of nanoscale wear and friction properties of individual metallic phases and phase boundaries.
