Mitigating Creep Anisotropy and Enhancing Performance in Additively Manufactured Ni‐Based Superalloys: A Review

Advanced Engineering Materials, EarlyView.
Additive manufacturing introduces pronounced microstructural and crystallographic anisotropy in Ni‐based superalloys, resulting in orientation‐dependent creep deformation and damage. This review identifies the key microstructural origins of creep anisotropy, examines their influence on dominant deformation mechanisms, and highlights processing ...

Detecting invariant manifolds using Lagrangian coherent structures [PDF]

, 2012
Using as reference test model the Planar Circular Restricted Three Body Problem, this paper explores its Lagrangian Coherent Structures, as well as its Hyperbolic Lagrangian Coherent Structures. The purpose is to identify stable and unstable manifolds

Numerical simulation of turbulent flow and heat transfer in a channel by the spectral element method: spatial resolution effect

Известия Томского политехнического университета: Инжиниринг георесурсов, 2016
Relevance. Turbulent flows are readily met in a variety of engineering applications. In particular, oil and gas transport through pipelines reaching 12 % of the oil-related power consumption is performed at very high Reynolds numbers, i. e.

Electrodeposition in Structural Lattices of Variable Architectures

Advanced Engineering Materials, EarlyView.
Electrodeposition enables geometry‐sensitive, autonomous void filling while simultaneously tuning chemical and mechanical properties. The development of approaches that can autonomously fill and heal material voids and yield composites with tailorable properties is increasingly relevant in engineering.

Statistical Properties of Coherent Structures in Two Dimensional Turbulence

, 2018
: Coherent vortices are ubiquitous structures in natural flows that affect mixing and transport of substances and momentum/energy. Being able to detect these coherent structures is important for pollutant mitigation, ecological conservation and many ...

Coherent structures and modeling: Some background comments [PDF]

, 1987
Coherent structures are discussed as a sequence of events (identifiable motions) in the flow which convert significant amounts of mechanical energies of the mean flow stream, into turbulent fluctuations.

Microstructure‑Dependent Phase Transformations Under High‑Pressure Laser Heating in Additively Manufactured AlCrFe2Ni2

Advanced Engineering Materials, EarlyView.
Additively manufactured AlCrFe2Ni2 with contrasting BCC/B2‐dominant and lamellar FCC + BCC/B2 microstructures exhibits the same pressure‐induced BCC/B2 → HCP transformation. Under laser heating at high pressure, HCP is destabilized, and a cubic BCC/B2 + FCC assemblage is recovered, while the lower‐scan‐speed microstructure transforms at a lower ...
