Advanced Engineering Materials, EarlyView.This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.

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.

Advanced Engineering Materials, EarlyView.This study applies machine learning regression to predict chromium layer thickness in decorative trivalent chromium electroplating, using 441 experiments from laboratory‐scale (1L) and pilot‐scale (14L) setups. Tree‐based models, particularly CatBoost, outperformed linear regression by capturing nonlinear parameter interactions (R2$R^2$ up to 0.77 ...

Prerogative legislation as the paradigm of bad law-making: The Chagos Islands [PDF]
Through a detailed examination of the British Indian Ocean Territory (Constitution) Order 2004 and its impact on the Chagos Islands (a small archipelago of coral atolls in the Indian Ocean and a British Overseas Territory) this dissertation describes the

Government Contract Law, Second Edition [PDF]
, 2003 The rapid developments in government contract law of the late 1990s and early 2000s have necessitated a new edition of this casebook, which offers the first contemporary one-volume casebook for a Government Contracts course.

Advanced Engineering Materials, EarlyView.This article presents an experimental and numerical modal investigation of composite sandwich structures using surfboards as model systems. By comparing different core materials and reinforcement strategies, the study demonstrates how local stiffeners influence vibrational response and introduce characteristic modal features, highlighting modal ...
