A Simulative Approach for the Prediction of Mesoscale Residual Stress Fields in Solution‐Strengthened Ferritic Ductile Iron

Advanced Engineering Materials, EarlyView.
This study presents a 3D representative volume element‐based simulation approach to predict mesoscopic residual stress and strain fields in silicon solid solution‐strengthened ductile cast iron. By modeling phase transformation kinetics with an enhanced Johnson–Mehl–Avrami–Kolmogorov model, the effects of varying cooling rates on residual stresses are ...

Computed tomography-osteoabsorptiometry for assessing the density distribution of subchondral bone as a measure of long-term mechanical adaptation in individual joints [PDF]

, 1989
To estimate subchondral mineralisation patterns which represent the long-term loading history of individual joints, a method has been developed employing computed tomography (CT) which permits repeated examination of living joints.

Residual Stress States in Microstructurally Graded PBF–LB/M Austenitic Steel Components

Advanced Engineering Materials, EarlyView.
This study examines microstructurally graded 316L rectangular tube profiles fabricated via PBF–LB/M using a dual‐laser system. A 1 kW top‐hat and a 400 W Gaussian laser create distinct grain sizes and crystallographic texture. Mechanical properties are linked to microstructural evolution driven by processing conditions.

CeO2 Nanostructures Prepared by Selective Water‐Soluble Sr3Al2O6(SAO)‐CeO2 Vertically Aligned Nanocomposite

Advanced Engineering Materials, EarlyView.
Highly textured CeO2 nanowires and nanoporous thin films are successfully synthesized by water dissolution of Sr3Al2O6 (SAO) from the SAO:CeO2 vertically aligned nanocomposites (VANs). The morphology of CeO2 can be varied by VAN composition. It demonstrates a new method for synthesizing nanostructured CeO2 without chemical etching or complex micro ...

Exploring the application of dual‐energy CT to discriminate sediment facies in a varved sequence

The Depositional Record
Dual‐energy X‐ray computed tomography consists of imaging objects using two incident X‐ray beams of different energy to distinguish the different compounds within a sample based on their density (electron density, ρe) and elemental composition (effective
