Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing

open access: yesAdvanced Engineering Materials, EarlyView.
This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

Parallel lives? Ethnic segregation in schools and neighbourhoods [PDF]

open access: yes
We provide evidence on the extent of ethnic segregation experienced by children across secondary schools and neighbourhoods (wards). Using 2001 Schools Census and Population Census data we employ the indices of dissimilarity and isolation and compare ...

A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

open access: yesAdvanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

What Drives Racial Segregation? New Evidence Using Census Microdata [PDF]

open access: yes
This paper sheds new light on the forces that drive residential segregation on the basis of race, assessing the extent to which across-race differences in other household characteristics can explain a significant portion of observed racial segregation ...

Occupational Segregation by Race and Ethnicity in the US: Differences across States [PDF]

open access: yes
Using the 2005–2007 American Community Survey, we analyze the occupational segregation of workers by race and ethnicity across states. Although the unconditional analysis shows great geographical variation in segregation, with the largest levels ...

Additive Manufacturing of Continuous Fibre Reinforced Composites: Process, Characterisation, Modelling, and Sustainability

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing provides precise control over the placement of continuous fibres within polymer matrices, enabling customised mechanical performance in composite components. This article explores processing strategies, mechanical testing, and modelling approaches for additive manufactured continuous fibre‐reinforced composites.

English Muslims and the Debates in Segregation

open access: yes, 2007
In the context of segregation, the issues around English Muslims have attracted critical attention from social scientists and policy makers. Past socio-econonmic indicators demonstrate that English Muslims, particularly those of Bangladeshi and ...

Modeling of particle segregation in a rotating drum [PDF]

open access: yes, 2010
Mixing of granular solids is a processing step in a wide range of industries. The fundamental phenomena in granule mixing are still poorly understood, making it difficult to a priori predict the effectiveness of mixing processes.

Measuring Segregation [PDF]

open access: yes
We propose a set of axioms for the measurement of school-based segregation with any number of ethnic groups. These axioms are motivated by two criteria. The first is evenness: how much do ethnic groups’ distributions across schools differ?

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

open access: yesAdvanced Engineering Materials, EarlyView.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...
