Scientists of the Max-Planck-Institut für Eisenforschung pioneer new machine learning model for corrosion-resistant alloy design. Their results are now published in the journal Science Advances
Atom probe tomography (APT) is a material analysis technique capable of 3D compositional mapping with sub-nanometer resolution. The specimens for APT are shaped as sharp needles (~100 nm radius at the apex), so as to reach the necessary intense electrostatic fields, and are typically prepared via focused ion beam (FIB) based milling.
The structures of grain boundaries (GBs) have been investigated in great detail. However, much less is known about their chemical features, owing to the experimental difficulties to probe these features at the near-atomic scale inside bulk material specimens. Atom probe tomography (APT) is a tool capable of accomplishing this task, with an ability…
We introduce a new experimental approach to the compositional and thermomechanical design and rapid maturation of bulk structural materials. This method, termed Rapid Alloy Prototyping (RAP), is based on semi-continuous high-throughput bulk casting, rolling, heat treatment and sample preparation techniques. 45 material conditions – i.e. 5 alloys with systematically varied composition, each modified by 9 different aging treatments – were produced and investigated within 35 hours. This accelerated screening of the tensile, hardness and microstructural properties as a function of chemical and thermomechanical parameters allows for the highly efficient and knowledge-based design of bulk structural alloys.
In order to prepare raw data from scanning transmission electron microscopy for analysis, pattern detection algorithms are developed that allow to identify automatically higher-order feature such as crystalline grains, lattice defects, etc. from atomically resolved measurements.
