Laser‐Based Closed‐Loop Controlled Heat Treatment for Residual Stress Relief of Additively Manufactured AlSi10Mg Components

Advanced Engineering Materials, Volume 27, Issue 1, January 2025.
This article presents a novel closed‐loop controlled laser‐based heat treatment (LB‐HT) using temperature feedback to reduce thermally induced residual stresses (RS) within AlSi10Mg laser powder bed fusion components. The results demonstrate that LB‐HT efficiently reduces near‐surface RS from 158 to 5 N mm−2, achieving a part displacement reduction up ...

Multifunctional Polymer Composites for Automatable Induction Heating with Subsequent Temperature Verification

Advanced Engineering Materials, Volume 26, Issue 20, October 2024.
Combining magnetic and luminescent supraparticles with a flexible polymer yields multifunctional composites for automatable induction heating with subsequent temperature verification. These composites heat up to, e.g., 200 °C within 2 s by applying an alternating current magnetic field.

Mechanical Energy Dissipation During Seismic Dynamic Weakening in Calcite‐Bearing Faults

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 9, September 2024.
Abstract Earthquakes are frictional instabilities caused by the shear stress decrease, that is, dynamic weakening, of faults with slip and slip rate. During dynamic weakening, shear stress depends on slip, slip rate, and temperature, according to constitutive laws governing the earthquake rupture process.

Metavalent Bonding in Cubic SnSe Alloys Improves Thermoelectric Properties over a Broad Temperature Range

Advanced Functional Materials, Volume 34, Issue 30, July 24, 2024.
The phase transition of SnSe from Pnma to Fm‐3m is realized by tailoring the chemical bonds. All the dopants that drive the phase transition prevail in a well‐defined region of a chemical bonding map. While the Pnma SnSe utilizes covalent bonding, the Fm‐3m SnSe employs metavalent bonding.
