Embrittlement of Metal by Solute Segregation-Induced Amorphization [PDF]
Physical Review Letters, 2010 Impurities segregated to grain boundaries of a material essentially alter its fracture behavior. A prime example is sulfur segregation-induced embrittlement of nickel, where an observed relation between sulfur-induced amorphization of grain boundaries and embrittlement remains unexplained.

Detection of Solute Segregation at Grain Boundaries [PDF]
Proceedings, annual meeting, Electron Microscopy Society of America, 1980 Studies of grain boundary segregation in metallurgical systems are traditionally based upon the premise that grain boundaries are more likely sites for solute atoms than their surrounding grains. This idea is manifested in experimnental studies which distinguish the solute

A Model for Segregation of Chromatin after Replication: Segregation of Identical Flexible Chains in Solution [PDF]
Biophysical Journal, 2011 We study the segregation of two long chains from parallel but randomly twisted start conformations under good solvent conditions using Monte Carlo simulations to mimic chromatin segregation after replication in eukaryotic cells in the end of prophase. To measure the segregation process, we consider the center-of-mass separation between the two chains ...

Applied Thermodynamics: Grain Boundary Segregation
Entropy, 2014 Chemical composition of interfaces—free surfaces and grain boundaries—is generally described by the Langmuir–McLean segregation isotherm controlled by Gibbs energy of segregation.

Metals, 2022 This work investigates the microstructure and inclusions of a compacted graphite iron (CGI) alloyed by Ce and La rare earth (RE) elements. In our study, alloying elemental distribution and solute segregation were characterized by methods of secondary ion

A Low Cost Solution for Automatic Plastic Segregation
International Journal of Engineering and Advanced Technology, 2020 Solid waste management is a universal issue that matters to every single person in the world. The solid waste management system is fundamentally labor intensive with very little collection efficiency. The available automatic plastic segregation techniques are based on thermal imaging and electrostatic properties of materials- these methods are ...

Macroscopic charge segregation in driven polyelectrolyte solutions
Soft Matter, 2022 Using coarse-grained simulations we show that a polyelectrolyte solution when driven by a steady external electric field undergoes a nonequilibrium phase transition from a homogeneously mixed phase to a macroscopically charge-segregated phase.

Journal of Materials Research and Technology, 2023 The stability and strength of the grain boundary (GB) structure are critical for the practical application of nanocrystals. This study systematically calculates the impact of the segregation of 26 transitional alloy elements on Cu Σ11 [110](113) GB using
