Quality Enhancement of Laser Powder‐Bed Fusion Parts by Acoustically Assisted Additive Manufacturing by Laser Powder‐Bed Fusion and its Application to Lattice Structures

Advanced Engineering Materials, EarlyView.
Additive manufacturing technologies like laser powder‐bed fusion offer great design freedom and individualization of products down to a batch size of one. However, parts fabricated with this technology suffer from poor quality. Acoustic assistance during the build process can minimize these drawbacks.

Influence of Testing Temperature on the Mechanical Performance of Brazed Conventionally and Additively Manufactured 316L Stainless Steel Joints

Advanced Engineering Materials, EarlyView.
This study reports for the first time the mechanical properties of brazed joints featuring Additively manufactured parts, such parts will likely need to be joined or combined with other components, and brazing offers a way of doing this for complex shapes without distortion. A new shear test methodology developed for such joints is also described.

Assessing the Microstructure of SnBiZn Alloys during Semisolid Treatment

Advanced Engineering Materials, EarlyView.
The development of Sn‐based alloys for semisolid processing is crucial for Industry 4.0. This study investigates Sn40Bi and Sn40Bi2Zn alloys, revealing that Zn refines Sn‐rich globules by pinning dendrite boundaries. Bi saturation occurs at 60 min, while Zn enhances globule microhardness at 90 min through solid solution strengthening.

A Simulative Approach for the Prediction of Mesoscale Residual Stress Fields in Solution‐Strengthened Ferritic Ductile Iron

Advanced Engineering Materials, EarlyView.
This study presents a 3D representative volume element‐based simulation approach to predict mesoscopic residual stress and strain fields in silicon solid solution‐strengthened ductile cast iron. By modeling phase transformation kinetics with an enhanced Johnson–Mehl–Avrami–Kolmogorov model, the effects of varying cooling rates on residual stresses are ...

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

Advanced 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
