Mechanism of microstructure and mechanical properties improvement through ultrasonic rolling pressing layer-by-layer and adaptive ultrasonic rolling method research in AlSi10Mg laser powder bed fused

Journal of Materials Research and Technology
In the process of laser powder bed fusion (L-PBF), the high-speed movement of the laser heat source causes uneven temperature and stress fields, thus, it results in dendrites, pores, micro cracks and residual stresses.

Powder characterisation techniques and effects of powder characteristics on part properties in powder-bed fusion processes

Virtual and Physical Prototyping, 2017
Powder-bed fusion is a class of Additive Manufacturing (AM) processes that bond successive layers of powder to facilitate the creation of parts with complex geometries. As AM technology transitions from the fabrication of prototypes to end-use parts, the

Rib‐Reinforced Ultralight and Ultra‐Strong Shell Lattices

Advanced Science, EarlyView.
This study thoroughly reveals the relation between the curvature and stress direction of triply periodic minimal surface (TPMS) thin shell lattices and proposes a novel rib reinforcement design strategy to incorporate ribs along the line of asymptotes (LOA) and the line of principal curvatures (LOC) to enhance the strength of ultralight TPMS shell ...

Deformable Eutectic Alloy With Near‐Theoretical Yield Strength via Hierarchical Nanoscale Multiphases and Sessile Defects

Advanced Science, EarlyView.
A CoCrFeNiTa0.4 eutectic high‐entropy alloy achieves a near‐theoretical yield strength of 2.6 GPa with 13.6% plasticity. This breakthrough stems from a hierarchical nanostructure (FCC‐Laves lamellae with L12/D022 precipitates), which alleviates the inter‐phase modulus/hardness mismatch through synergistic strengthening and toughening, guiding the ...
