Tilt Grain-Boundary Effects in S- and D-Wave Superconductors

, 1998
We calculate the s- and d-wave superconductor order parameter in the vicinity of a tilt grain boundary. We do this self-consistently within the Bogoliubov de Gennes equations, using a realistic microscopic model of the grain boundary.

The Impact of High‐Productivity Processing on the Fatigue Failure of an Additive Manufactured Superalloy HAYNES 282

Advanced Engineering Materials, EarlyView.
The low cycle fatigue life of additive manufactured HAYNES® 282® superalloy was investigated for conventional and high‐productivity processing: samples of the former lasted 1400–1700 cycles, while samples of the latter failed at ~ 1200 cycles, at 760 °C and 1% strain.

Effects of Hot Compression on Grain Boundary Evolution and Twin Boundary Characteristics on the Material Properties of Inconel 617 Alloy

Metals
The evolution of grain size and special grain boundary in Inconel 617 alloy was analyzed by electron backscatter diffraction (EBSD). It was found that during hot compression, dynamic recrystallization (DRX) occurs, the grain size changes, and a twinning ...

Electron relaxation times and resistivity in metallic nanowires due to tilted grain boundary planes

, 2015
We calculate the resistivity contribution of tilted grain boundaries with varying parameters in sub-10nm diameter metallic nanowires. The results have been obtained with the Boltzmann transport equation and Fermi's golden rule, retrieving correct state ...

Interactions between Molten High‐Silicon Electrical Steels and Carbon‐Bonded MgO Refractories Based on Recyclates

Advanced Engineering Materials, EarlyView.
This study examines how several molten high‐silicon electrical steels interact with both conventional and recycled MgO–C refractories. For this, various immersion experiments are conducted. In addition to infiltration, a number of mechanisms are identified and explained that control the corrosion of the refractory material.
