Single‐Crystal Castability of CM186LC Nickel‐Based Superalloy

Advanced Engineering Materials, EarlyView.
The optimal conditions to obtain single‐crystal (SX) castings of the directional solidification nickel‐based superalloy CM186LC, are investigated. Cylindrical samples are cast via a proprietary SX Bridgman process. The effect of solidification rates (V) ranging from 1 to 10 mm⋅min−1 on the microstructure is explored.

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.

(Nb,Ti)(C,N)‐Precipitates in High‐Strength Low‐Alloyed Steels—Modeling, Characterization and Validation

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.

Additive Processing of Ti‐17 by Wire Arc Directed Energy Deposition: An Investigation of the Microstructure and Mechanical Properties

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.
