Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

Advanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

Multimodal Data‐Driven Microstructure Characterization

Advanced Engineering Materials, EarlyView.
A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

Atomic disorder and thermal stability in laser beam-shape-tailored 3D-Printed Zr-based bulk metallic glass under in-situ heating during high-energy X-ray diffraction

Materials Today Advances
This study demonstrates that tailoring the laser beam intensity profile in laser powder-bed fusion (LPBF) significantly influences the thermal and mechanical behavior of Zr-based bulk metallic glasses (BMGs).

Structured beam generation and optical trapping of low-index particles using a semi-nonlinear Michelson interferometer

Frontiers in Physics
In this work, we propose a semi-nonlinear Michelson interferometer (SNMI) for controllable laser beam shaping and optical manipulation. By placing a Kerr-type nonlinear medium into one arm of the interferometer, the phase difference between the two arms ...

Ultrafast beam pattern modulation by superposition of chirped optical vortex pulses

Scientific Reports, 2022
As an extension of pulse shaping techniques using the space–time coupling of ultrashort pulses or chirped pulses, we demonstrated the ultrafast beam pattern modulation by the superposition of chirped optical vortex pulses with orthogonal spatial modes ...
