Advanced Engineering Materials, EarlyView.This article examines how build orientation, thickness, and loading rate affect the tensile and compressive properties of LS‐manufactured polyamide 12 12 parts. Through over 120 experiments, it reveals strong ductility anisotropy in tension, minimal compressive sensitivity, and significant thickness and strain rate dependencies.

Scattering, absorption and emission of highly excited strings
Journal of High Energy PhysicsWe study tree-level scattering processes of arbitrary string states using the DDF formalism and suitable coherent vertex operators. We obtain new exact compact formulae for heavy-heavy-light-light scattering amplitudes in open or closed bosonic string ...

Advanced Engineering Materials, EarlyView.A laboratory‐scale procedure is developed to evaluate the efficiency of melt‐cleaning and drossing fluxes during aluminium alloy recycling, studying their effects on melt cleanliness and tensile properties of secondary foundry alloys. This work provides a practical tool for foundries and aluminium refiners to assess the efficiency of salt fluxes in ...

Advanced Engineering Materials, EarlyView.This study identifies 12 wt% indium (In) as the optimal composition for Sn0.5Ag0.7Cu5Bi solder joints, achieving 87% ductile fracture and 81% suppression of intermetallic compound (IMC) growth versus 4 wt% In. High‐In alloys (15–17 wt%) show abnormal IMC thickening due to thermal activation.

Advanced Engineering Materials, EarlyView.Steel samples are investigated using complementary simulations and measurements. Transmission electron microscopy in bright‐field mode, combined with energy‐dispersive X‐ray spectroscopy maps for titanium and niobium, reveals distinct particle populations. Simulations reproduce these in size and composition.

Advanced Engineering Materials, EarlyView.This study focuses on processing the titanium alloy Ti‐17 using wire arc directed energy deposition (waDED), with an emphasis on the microstructure and mechanical properties. The waDED typical heat‐affected zone banding is characterized and related to the local mechanical properties.
