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.

The nature of elastoplastic transition in low-carbon steel samples with and without welds [PDF]

, 2017
This paper describes the influence of a weld on elastoplastic transition in low-carbon steels. Depending on the level of internal stresses in the zone of the weld, the formation of Chernov-Lüders bands can occur either exactly in the weld or near it.

Impact of Various Rotary Friction Welding Process Parameters on the Mechanical Properties of a Steel–Aluminum Joint

Advanced Engineering Materials, EarlyView.
Rotary friction welding of steel E355 and the aluminum alloy EN AW‐6082 can lead to the formation of brittle intermetallic phases. The primary process parameters are varied in order to determine their influence on this intermetallic phase formation and the resulting mechanical properties.

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.
