Creep‐Induced Microstructural Evolution in an A2‐B2 Superalloy

open access: yesAdvanced Engineering Materials, EarlyView.
A 27.3Ta‐27.3Mo‐27.3Ti‐8Cr‐10Al (at.%) refractory high‐entropy alloy with precipitation‐strengthened A2‐B2 microstructure was studied by creep tests at 1030°C, which demonstrate a transition in deformation mechanisms in the range of 100–150 MPa applied stress. This is associated with changes in dislocation–precipitate interactions. Relevant deformation

High‐Temperature Nanoindentation of Metals: Assessing Thermal Drift, Frame Compliance, and Chemical Composition Effects on the Reported Mechanical Properties

open access: yesAdvanced Engineering Materials, EarlyView.
Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...

(Post)structuralism

open access: yes, 2016
This chapter suggests that structuralism and poststructuralism should be understood as part of a ‘turn’ in social theory and philosophy to ‘systems.’ It explores Claude Lévi-Strauss’s approach to myth, demonstrating that his approach entwines elements from linguistics and dynamic systems theory that point ‘back’ to formalism and ‘forward’ to ...

Post-Structuralism

open access: yes, 2011
As regards the study of consumers and the consumption of everyday culture, post-structuralism signifies a significant departure from the structuralist analyses that it succeeded. Whereas in a structuralist analysis of consumption the patterns of consumption are ascertained through the revelation of some deep structure, in post-structuralist analyses of
