Solid‐State Diffusion and Intermetallic Phase Formation in Roll‐Bonded Mg–Zn Composites With Kirigami‐Patterned Inlay

open access: yesAdvanced Engineering Materials, EarlyView.
Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

Energy and climate policies to 2020 : the impacts of the european " 20/20/20 " approach [PDF]

open access: yes
Purpose :The study aims to quantify the possible interactions between the three European objectives in the horizon of 2020 : (i) the reduction of 20% of greenhouse gas emissions (GHG) (2) the saving of 20% of the European energy consumption and (3) a ...

Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

open access: yesAdvanced Engineering Materials, EarlyView.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

An international agreement with full participation to tackle the stock of greenhouse gases [PDF]

open access: yes
This paper analyzes greenhouse gas emissions that build up an atmospheric stock which depreciates over time. Weakly renegotiation- proof and subgame perfect equilibria in a game of international emission reduction exist if countries put a sufficiently ...

Karl Popper and the Mechanisms of Hydrogen Embrittlement

open access: yesAdvanced 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.
