The Effect of Thickness, Build Orientation, and Loading Rate on the Tensile and Compressive Properties of Selective Laser Sintering Polyamide 12 Specimens

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.

Laboratory‐Scale Procedure for Evaluating the Flux Efficiency on Melt Cleanliness and Tensile Properties of Recycled Aluminum Alloys

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 ...

Microstructural Evolution and Mechanical Property Degradation of Sn0.5Ag0.7Cu5Bi Solder Joints with High Indium Alloying

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.

Fatigue Performance of Additively Manufactured Ti‐6Al‐4V: Impact of Different Kinds of Porosities, Surface, and Heat Treatments in Laser Powder Bed Fusion Productivity Parameters

Advanced Engineering Materials, EarlyView.
Ti‐6Al‐4V samples produced by laser‐powder bed fusion are tested for static and dynamic mechanical properties to systematically evaluate the effects of surface roughness and internal porosity when using productivity parameters. The most detrimental impact to fatigue is caused by surface roughness, lack of fusion and keyhole porosity in descending order.
