Hydrogen‐Assisted Fracture of Iron‐Based Fe–Ni–Al Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
Principal relations and fracture mechanisms of single‐phase and precipitate‐strengthened Fe–Ni–Al alloys subjected to prior electrochemical hydrogen charging are identified. The mechanisms of hydrogen effect on strength and microhardness are discussed, including hydrogen‐induced increase in microhardness and the role of hydrogen in fracture behavior ...

Slip Localization Intensification Mediated by Grain Boundary Sliding in a Polycrystalline Nickel‐Based Superalloy

open access: yesAdvanced Engineering Materials, EarlyView.
The temperature dependence of fatigue behavior in nickel‐based superalloys is investigated through high‐resolution measurements of plastic localization. While increasing temperature reduces localization and enhances fatigue performance in René 88DT, Inconel 718 exhibits a sharp degradation at intermediate temperature due to intensified slip ...

Does Decentralized Welfare Reform Lead to a Race to the Bottom in Local Economic Development and Local Public Services?

open access: yes
This paper tests the hypothesis that devolution of welfare programs leads to heightened intergovernmental competition and a "race to the bottom" in the provision of local public services.
