  • Four scientists from Freiburg have succeeded for the first time to simulate the localized growth of silicon crystals using shear-induced amorphization and recrystallization. In the future, experts could use this concept to tailor crystalline silicon structures for nanotechnology applications, such as nanoelectronics. “Triboepitaxy”, the fundamental idea that could make this possible, is presented by the team in the journal “Physical Review Letters”.

    Storing hydrogen safely: Fraunhofer IWM evaluates materials for tubular storage systems

    September 28, 2021

    Hydrogen has an important role to play in the energy transition. Science and industry are currently working on storage and transport systems for hydrogen. The basis for this is to precisely describe and assess the behavior of metallic materials, especially steels, when they are in contact with hydrogen. As part of the BMBF lead project H2Mare, the Fraunhofer IWM will develop and evaluate criteria for assessing materials and components for so-called tubular storage systems in the joint project H2Wind. The findings will contribute to the accident-proof and durable operation of a real storage infrastructure for hydrogen.

  • Deciphering wear with friction tests and atomistic simulations / 2021

    Interaction between DLC coatings and ZDDP lubricant: it all depends on the right hardness!

    August 17, 2021

    In combustion engines, in plain bearings and in aerospace: diamond-like carbon coatings (DLC) reduce friction and wear in frictional contacts. In most cases, the lubricants used in bearings and engines contain the additive zinc dialkyl dithiophosphate (ZDDP), which in turn protects steel surfaces against wear. Unfortunately, it can attack the DLC layer, leading to premature failure. Researchers at the Fraunhofer IWM have discovered how the antagonistic interaction between the two substances occurs. In the journal Nature Communications, they explain why DLC layers can also be too hard in combination with ZDDP.

  • In a collaborative effort to tackle the enormous challenge of building a common National Research Data Infrastructure NFDI, entire research areas across Germany are working together in subject-specific consortia. As one of ten consortia in the second round, NFDI-MatWerk is now receiving five years of funding for Materials Science and Engineering. The consortium consists of renowned research organizations, including 10 applicants and 15 associated partners and is represented by the speaker Prof. Dr. Chris Eberl from Fraunhofer Institute for Materials Mechanics. It focuses on the infrastructure development for a shared materials data space.

  • Pioneering work for the application of integrated material data rooms / 2020

    Fraunhofer IWM closes gaps in the mechanics of materials digital value chain

    November 24, 2020

    The greatest potential of digitalization in companies in which materials play a prominent role lies in the cross-process linking of materials data. This promises to shorten component development times, faster optimization of complex manufacturing processes and more reliable plant operation. The problem is the very heterogeneous nature of materials data, which makes linking within this data extremely complex. The research project MaterialDigital of the state of Baden-Württemberg under the leadership of the Fraunhofer Institute for Mechanics of Materials IWM in Freiburg has now made great progress in structuring materials data into a continuous data space.

  • Special coating protects steel from hydrogen ‘attack’ / 2020

    Almost no evidence of brittleness

    July 27, 2020

    Regeneratively produced hydrogen is an ideal energy carrier, which will be used in future applications as fuel cells and in cars; it will supplement natural gas as an energy source. But atomic hydrogen often induces brittle behavior in metals at high temperatures. Lukas Gröner of the Fraunhofer IWM, MikroTribologie Centrum µTC, has now developed a robust coating that effectively protects steel from the penetration of hydrogen. The barrier effect of this so-called MAX-phase layer is 3500 times greater than that of untreated steel. He published his results in the journal materials (doi: 10.3390/ma13092085).

  • Calculation of dry friction using molecular dynamics simulations / 2020

    Puzzle about passivation of low-friction, hard carbon coatings solved

    June 09, 2020

    Diamond and diamond-like carbon (DLC) are used as extremely durable surface coatings in frictional contacts – from aerospace components to razors. They reduce friction and wear in bearings and valves by means of so-called passivation layers, which prevent other materials from bonding to the coating. Until now, it was unclear how these passivation layers should be designed to achieve minimal friction. Researchers at the Fraunhofer Institute for Mechanics of Materials IWM, MicroTribology Centrum µTC, have now achieved a breakthrough in understanding the relationship between passivation and friction. The unexpected results have been published in the journal "ACS Applied Materials & Interfaces".

  • Computational models based on molecular structure properties / 2020

    Characterizing and designing lubricants on the computer

    April 03, 2020

    Lubricated shafts, bearings and gears only run 'like clockwork' when the components slide on a perfect lubricating film, generating as little friction, wear and energy loss as possible. To achieve this, engineers need to know the behavior of the lubricant film in the so-called tribo-contact, which is difficult to measure experimentally. In order to ascertain such behavior, the Fraunhofer IWM, MicroTribology Center μTC makes lubricant properties calculable using atomistic methods and has recently published exciting findings on one of the central parameters, the pressure dependence of lubricant viscosity, in the scientific journal Physical Review Letters.

  • Atomistic simulations speed up research on exciting new battery materials / 2020

    Highly promising solid electrolytes for high-performance lithium-ion batteries

    January 07, 2020

    High-performance, long-lasting energy storage devices are crucially important for many future-oriented technologies: e.g. for electromobility, for mobile end devices such as tablets and smartphones as well as for the efficient use of energy from renewable sources. Dr. Daniel Mutter from the Freiburg-based Fraunhofer Institute for Mechanics of Materials (IWM) was able to clarify what the chemical composition of solid ceramic electrolytes should be in order to ensure good performance in lithium-ion batteries. The research was published in the Journal of Applied Physics (https://doi.org/10.1063/1.5091969). Such solid electrolytes are more environmentally friendly than traditional liquid electrolytes and could make lithium-ion batteries significantly safer and more efficient.

  • Innovative glass-bending process heralds exciting new applications / 2019

    How to bend flat glass perfectly around corners

    October 01, 2019

    Researchers from the Fraunhofer Institute for Mechanics of Materials IWM have developed a new process that can bend sheets of glass to produce angular corners. Unlike conventional processes, this does not impair the optical properties of the glass. Bent glass looks destined to play a key role in future building design, and there are also potential applications in the fields of medical technology and industrial design.
