Multimaterial Approach to Improve the Mechanical Properties of a Novel Modified Auxetic Reentrant Honeycomb Structure

open access: yesAdvanced Engineering Materials, EarlyView.
A multimaterial approach is introduced to improve upon auxetic structures by combining two different polymers into the same reentrant honeycomb structure via additive manufacturing. The deformation behavior as well as the resulting Poisson's ratio are thereby improved significantly.

Vacuum‐Formed Composites Based on a Polyolefin and a High Content of Biomass‐Waste Fillers

open access: yesAdvanced Engineering Materials, EarlyView.
It is shown here that by the use of a very ductile polymer matrix, it is possible to vacuum‐form products that contain up to 25% of hard biofillers with still ductile properties. The results are promising and opens up for the use of engineered biocomposites derived from industrial side‐stream biofillers in vacuum‐formed products. A strategy to increase

High‐Temperature Oxidation of the CrFeNi Medium‐Entropy Alloy

open access: yesAdvanced Engineering Materials, EarlyView.
The oxidation behavior of equiatomic CrFeNi MEA is a key issue that determines this material's suitability for high‐temperature application. The understanding of long‐term behavior is even more crucial than short‐term corrosion effects. The alloy is exposed to synthetic air at 1000, 1050, and 1100 °C for 24, 100, and 1000 h and systematically compared ...

Residual Stress States in Microstructurally Graded PBF–LB/M Austenitic Steel Components

open access: yesAdvanced Engineering Materials, EarlyView.
This study examines microstructurally graded 316L rectangular tube profiles fabricated via PBF–LB/M using a dual‐laser system. A 1 kW top‐hat and a 400 W Gaussian laser create distinct grain sizes and crystallographic texture. Mechanical properties are linked to microstructural evolution driven by processing conditions.
