In Situ Micromechanical Study of Bimodal γ′–γ″ Precipitate Assemblies in Ni–Cr–Al–Nb Superalloy

Advanced Engineering Materials, EarlyView.
A Ni–Cr–Al–Nb superalloy with a bimodal γ′–γ″ precipitate distribution is developed. Composite precipitate assemblies form through heterogeneous nucleation, effectively impeding dislocation motion. Micropillar compression reveals high strength at room and elevated temperatures, governed by precipitate shearing, with coupled faulting mechanisms ...

The Meaning of Researchers' Subjectivity

Forum: Qualitative Social Research, 2015
In the article, I explore researchers' subjectivity and it's marginalization in the social sciences, especially in sociology. Based on a review of the research in which researchers' subjectivity plays a role, I will briefly give an overview of their ...

Molecular Dynamics Studies of Shape Memory Polymers: From Bead–Spring Models to Atomistic Simulations

Advanced Engineering Materials, EarlyView.
Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

Biographical Uncertainties Around the Turn of the 20th and 21st Centuries and How They Were Overcome—A Comparative Historical Analysis Based on the Example of Artists

Forum: Qualitative Social Research, 2008
Many social scientists have concluded that people in contemporary society feel exposed to increasing biographical uncertainties and therefore find it more and more difficult to predict, estimate, and plan the course of their lives. The same view prevails

Microstructure Reconstruction in Battery Electrodes Using Machine Learning Based on Low‐Voltage Focused Ion Beam–Scanning Electron Microscopy Tomography Images

Advanced Engineering Materials, EarlyView.
Low‐voltage FIB‐SEM tomography combined with a image preprocessing pipeline improves phase contrast and enables reliable machine‐learning segmentation of conductive networks in lithium‐ion battery electrodes. Structural descriptors are extracted from segmented images, done semimanually and automated, and compared.

Review Essay: Qualitative Research for the Education of Mankind

Forum: Qualitative Social Research, 2003
For quite a long time, the "scientific foundation" of foreign language teaching methods, of school curricula, and of "European Frameworks" seemed to be granted by quantitative psychological studies in conjunction with one or the other linguistic theory ...

Modeling Dislocation Cutting of γ′ Precipitates in Ni‐Base Superalloys: Linking Atomistic and Dislocation Dynamics Simulations

Advanced Engineering Materials, EarlyView.
Dislocation cutting of γ′ precipitates in Ni‐based superalloys is investigated by linking atomistic simulations with discrete dislocation dynamics. The critical cutting stress is shown to be governed by the antiphase boundary energy, while line tension effects promote edge‐preferred cutting.

Review: Cornelia Schweppe (Ed.) (2003). Qualitative Forschung in der Sozialpädagogik [Qualitative Research in Social Pedagogy]

Forum: Qualitative Social Research, 2006
Cornelia SCHWEPPE's anthology provides us with a map for finding a way through the various discussions and methods of research concerning social pedagogy, keeping in mind the chasm that exists between the actual conception of social pedagogy that exists ...

Continuous Stiffness Graded Metal–Ceramic Femoral Stems: UMAT‐Based Design and Finite Element Assessment

Advanced Engineering Materials, EarlyView.
Functionally graded metal–ceramic femoral stems are engineered through continuous UMAT‐based stiffness tailoring, eliminating discrete material interfaces while enhancing biomechanical compatibility. Low‐index power‐law gradation optimizes load transfer, reduces stress shielding, and controls implant–bone micromotion, highlighting a materials‐design ...
