Microstructure-Informed Prediction of Transformation Products in C-Mn and C-Mn-Nb Steels for Data-Driven Process-Window Design

Marie Stiefel, Björn-Ivo Bachmann, Martín Müller, Dominik Britz et autres

Controlling the final microstructure of C-Mn and microalloyed C-Mn-Nb steels requires understanding how the prior austenite state and cooling path determine the transformation products, morphology, and mechanical response. In this work, a microstructure-informed prediction framework was developed to evaluate which transformation products …

A Systematically Designed Open-Access SEM Dataset and Robustness Benchmark for Machine Learning-Based Microstructure Segmentation: A High-Chromium Cast Iron Case Study

Björn-Ivo Bachmann, Marie Stiefel, Martin Müller, Frank Mücklich

This record provides an open-access scanning electron microscopy (SEM) dataset of high-chromium cast iron (HCCI, 26 wt.% Cr) microstructures, designed to isolate acquisition-induced image variance from material-induced variance. The dataset comprises 777 micrographs systematically acquired across eight controlled variation axes: four SEM …

Generation, characterization and modelling of bio-inspired asymmetric topographic structures via ps-pulsed Direct Laser Interference Patterning on metallic surfaces

Silas Schütz, Sebastian Suarez, Daniel Wyn Müller, Frank Mücklich

This study presents a comprehensive approach for generating bioinspired asymmetric surface structures on copper alloys and tin-coated substrates using picosecond-pulsed Direct Laser Interference Patterning (ps-DLIP). By introducing controlled tilt angles during processing, sawtooth-like morphologies were fabricated and quantitatively characterized through confocal laser …

Geometry-Driven Asymmetric Tribological Response in Laser-Patterned Cu Surfaces

Sebastian Suarez, Bruno Alderete, Fabian Kay Bonner, Silas Schütz et autres

Abstract This study investigates the fabrication of anisotropic saw-tooth topographies on copper surfaces using direct laser interference patterning (DLIP). By varying the structural periodicity (2, 7.5, and 10 µm) and manufacturing inclination angles (15, 30, and 45°), this work assesses the impact …

Thermal path dependence of secondary carbide precipitation kinetics and morphology in high-Cr cast irons

M.A. Guitar, U.P. Nayak, Frank Mücklich

• Heating rate is the dominant factor controlling secondary carbide (SC) size and fraction, outweighing holding time. • Slow heating (1 °C/min) yields SC 3–5 × larger than fast heating (10 °C/min) due to precipitation during the ramp. • Furnace cooling increases …

Multiscale hierarchical surface structuring of zirconia using femtosecond laser and chemical etching: implications for cell response and antibacterial performance

Nerea Garcia-de-Albeniz, Daniel Wyn Müller, Frank Mücklich, Maria‐Pau Ginebra et autres

, but it did not result in a synergistic improvement on cellular responses. Indeed, among all tested surfaces, the non-etched linear pattern (L3) consistently exhibited the most favorable outcomes -enhancing hMSC adhesion, migration, and osteogenic differentiation and mineralization, while reducing bacterial colonization …
