Integrated modelling: Coupling of surface evolution and plasma-impurity transport

Nuclear Materials and Energy, 2020
During the interaction of the scrape off layer (SOL) plasma with the first wall the evolution of both wall and plasma are tightly coupled: The erosion of the first wall leads to an impurity concentration in the plasma which affects the particle and power

Plasma surface interactions in impurity seeded plasmas [PDF]

Journal of Nuclear Materials, 2011
Abstract With tokamak devices developing towards higher heating powers, and carbon plasma facing components being increasingly replaced by high-Z materials like tungsten, impurity seeding for radiative power dissipation gains more importance. This review summarizes the core and divertor radiative characteristics of potential seeding species, namely ...

Effect of Impurity Reduction on Mechanical Properties of Fe29.5Ti70.5 Alloy Prepared by Pretreated Ti Scraps [PDF]

Archives of Metallurgy and Materials, 2021
Ferrotitanium can be produced as a method of recycling Ti scraps. The eutectic composition of ferrotitanium, Fe29.5Ti70.5, can be obtained as a nanocrystalline phase due to relatively low melting point. Fe29.5Ti70.5 in which FeTi and β-Ti form a lamellar
