Advanced Engineering Materials, EarlyView.Disordered (Fe50Co50)1−xPtx thin films exhibit a pronounced anomalous Nernst effect (ANE) with a strong composition dependence on both rigid and flexible substrates. The transverse thermoelectric response peaks near 22.5 at.% Pt, accompanied by enhanced αxy/σxy scaling, thermal transport, and ANE sensitivity.

Numerical Modeling and Cementing Countermeasure Analysis of Casing Shear Damage in Shale Reservoir
Shiyou jixie, 2016 Casing shear damage arising from rock sliding is common in the hydraulic fracturing of shale gas development. Casing damage in fracturing at a certain stage may cause tool trip-in failure in the follow-up fracturing operation,and thereby result in ...

Influence of an Oxygen‐Free Atmosphere on Diamond‐Single‐Grain Scratching of Ti–6Al–4V
Advanced Engineering Materials, EarlyView.Single‐grain scratching of Ti–6Al–4V is investigated under controlled, oxygen‐free, and ambient atmospheres using a novel experimental setup with in situ high‐speed imaging. The approach enables direct observation of chip formation and adhesion under suppressed oxidation.

Mechanical properties of natural gas wellbore structure under non-uniform load
Meitan kexue jishuIn areas where natural gas and coal resources overlap, the movement of overburden caused by high-intensity coal mining causes radial compression and deformation or even destruction of the natural gas well body structure within the protective coal pillar.

Rigidity of lattice domes [PDF]
The means of ensuring total rigidity of lattice domes, using comparison with solid shells of 1-3 layers are discussed. Irregularities of manufacture, processing, and other factors are considered, as they relate to diminution of rigidity.

Evaluating Energy Absorption Performance of Filled Lattice Structures
Advanced Engineering Materials, EarlyView.Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys
Advanced Engineering Materials, EarlyView.This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

Effect of Repeated Perforation on Casing Strength
Shiyou jixie, 2017 In order to avoid the casing damage and casing deformation caused by unplanned perforation, the effect of repeated perforation on the anti-collapse strength of the casing has been analyzed.
