Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing

Advanced Engineering Materials, EarlyView.
This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

Tracing natural gas migration by integrating organic and inorganic geochemical data: A case study of the Jurassic gas fields in western Sichuan Basin, SW China

Petroleum Exploration and Development, 2017
Based on the integrated geochemical and isotopic analysis of natural gases, formation waters, authigenic minerals, and fluid inclusions, a set of organic and inorganic geochemical tracing parameters, including methane/ethane ratio (C1/C2), N2 content ...

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

Advanced Engineering Materials, EarlyView.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

An integrated model for conglomerate reservoir quality classification based on graph attention and multiscale multimodal features

Scientific Reports
Conglomerate reservoirs are controlled by the interaction of multi-scale sedimentary architectures and diagenetic processes, resulting in highly heterogeneous and spatially discontinuous reservoir properties and geomechanical characteristics.

Strike-slip fault system and its control on ediacaran hydrocarbon system in central Sichuan Basin: insights from petrology, U-Pb dating and seismic interpretation

Frontiers in Earth Science
Strike-slip faults are closely related to the enrichment of hydrocarbon resources, with a series of large oil and gas fields associated with strike-slip faults discovered in regions such as the Ordos Basin in China and the West Siberian Basin.

Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Log Interpretation Method for In-Situ Stress in Ultra-Deep Basement Gas Reservoirs

Cejing jishu
To address the current challenges in predicting in-situ stress in ultra-deep basement gas reservoirs, such as the scarcity of measured data and unclear adaptability of log interpretation methods, and to support the efficient exploration and development ...

Understanding the Stochastic Nature of Process Parameter Development of Blown Powder Laser Beam Directed Energy Deposition Additive Manufacturing of Pure Molybdenum

Advanced Engineering Materials, EarlyView.
Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the

Multimodal Data‐Driven Microstructure Characterization

Advanced Engineering Materials, EarlyView.
A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

Field tests of CO2 huff-n-puff technology in Nanchuan normal-pressure shale gas field

Shiyou shiyan dizhi
Due to the high proportion of adsorbed methane and weak formation energy, the recovery rate of normal-pressure shale gas reservoirs is generally less than 30%.
