We would like to draw your attention to the Symposium "30 Years of Nanoindentation with the Oliver-Pharr Method and Beyond“ at TMS 2022, to be held February 27 - March 3, 2022 in Anaheim, CA, USA.
You can to submit your abstract for this TMS Symposium until July 1, 2021.
The origin of nanoindentation can be traced to the 1980s with the development of the first instrumented hardness testers providing submicrometer accuracy. However, it took the 1992 seminal publication by W.C. Oliver and G.M. Pharr to effectively launch the field. Their novel data evaluation procedure, later dubbed the “Oliver-Pharr method”, has directly enabled numerous transformative research efforts in a diverse range of fields spanning materials science, geology, biology and medicine. Up to now, it remains indispensable for ensuring the service performance and lifetime of essential small components, such as thin films and coatings, electronic sensors and MEMS.
This symposium aims at bringing together the different generations of researchers, as well as the different fields and applications. It will highlight the amazing range of applications and the robustness of the Oliver-Pharr method. A mixture of well-established invited speakers and promising younger researchers will address how everything started, how nanoindentation is currently used, and what the future of small-scale mechanical testing might look like.
Topics of interest:
• General aspects of nanoindentation including historical background
• Nanoindentation in-method development, standardization
• New approaches towards data science
• Dynamic nanoindentation (CSM, CMX, dynamics….)
• Refinements in understanding
• Indentation Size Effects
• Thermally activated deformation behavior
• Extreme testing environments, e.g. high and low temperatures, irradiation, electrochemical or high strain rates
• Complex loading conditions, such as cyclic fatigue, fracture testing
• In-situ testing in SEM, TEM or synchrotron
• Stress-strain measurements, e.g. from spherical nanoindentation
• Structural and functional materials; thin films, metals, ceramics, amorphous & crystalline
• Soft and viscoelastic materials behavior
The platform is open for submissions until July 1, 2021:
Additionally, we would like to draw your attention to the related JOM Topic issue “30 Years of Oliver-Pharr: Then, Now and the Future of Nanoindentation” set for publication in June 2022 – i.e. exactly 30 years after the seminal publication introducing the Oliver-Pharr Method.

Symposium CT03 - Imaging Materials with X-Rays—Recent Advances with Synchrotron and Laboratory Sources
Abstract submission open from September 24th to October 29th.
The last decade has seen a tremendous evolution of x-ray imaging and microscopy. This has been driven by the rapid development of third and fourth generation x-ray facilities, as well as new laboratory sources and x-ray optics capable of producing beams routinely below 50 nm in size. The high penetrating power, extreme sensitivity of x-rays to strain and defects and the tunability of these new sources to access x-ray fluorescence of much of the periodic table has enabled in situ or operando studies of nano-scale properties materials. It is worth also emphasizing that small x-ray beams may also be used to induce an electrical current or light emission in the nano-object enabling enhanced scanning probe and photo excitation studies.Beyond a discussion of the methods which have been developed, and are still an object of active research (coherent diffraction imaging in forward or Bragg or full field imaging conditions, nano x-ray fluorescence imaging, micro-Laue diffraction …), this symposium aims to review the materials science issues that these new tools can help solving. The range of materials science topics and related applications is indeed very large: electronic and optoelectronic devices (including flexible devices), transport properties, photovoltaic applications, catalysis, energy harvesting and storage, and even structural materials.
In all these areas, being able to investigate local structure-function relationships at the nano-scale during operation is a fundamental issue. The techniques described above have begun to make a major impact on these fundamental materials science questions. Our invited speakers, as well as the growing community of x-ray facility users, will present a complete overview of the capabilities and science being engaged with x-ray imaging and microscopy. These capabilities are only going to grow with the new, high brightness, synchrotrons and tabletop facilities appearing and being planned worldwide.

At the Max-Planck Institut für Eisenforschung in the Department Structure and Nano-/Micromechanics of Materials (Prof. G. Dehm) they offer a PhD student position in:
"Atomistic Computer Simulation of Grain Boundary Structure and Mechanics"
Understanding how grain boundaries influence plasticity will lead to significant advances in material design. In the context of the department’s research, the overarching aim of this PhD project is to connect grain boundary structures in fcc metals to physical properties.
Your tasks will be to employ molecular dynamics simulations combined with Monte Carlo techniques to predict grain boundary structures at an atomic level and to model their mechanical behavior. A part of the project will be focused on investigating the influence of alloying elements in order to work towards deriving grain boundary design principles for improved materials properties. All of the work is expected to be performed in collaboration with the experimental activities of the department.You have a Masters degree with good to excellent marks in Physics, Material Science, Mechanical Engineering, or a related field and you would like to work on challenging problems in Nano- and Micro-Mechanics and Materials Science. Some prior computer simulation or programming experience (especially with Python or C++) is advantageous.
The working language at our institute is English; sufficient proficiency in English to communicate effectively on scientific topics is required.
