Molecular Dynamics Studies of Grain Boundary Mobilities in Metallic and Oxide Fuels
… helpful as a baseline, but real materials have solutes or impurities (both intentionally and unintentionally) which are known to affect GB mobility by processes such as solute drag and Zener pinning. Additionally, in reactors, nuclear fission can produce many fission products, each of which acts …

Effect of microalloying on pearlite transformation of high carbon wire steels
… of vanadium distribution in austenite. Solute drag of niobium in austenite was identified as a possible mechanism for delay of pearlite transformation with niobium additions. Samples of the V and V+Nb alloys were heat treated by quenching from 1093 ° C for assessment of the state of Nb. …

Stress Relaxation of AA 5182 During Hot Deformation
… and low strain rate diffusion regime termed solute drag (SD) which is modeled with an equation posed by Mukherjee and fit to AA 5182 by Chen. The second regime is active at high temperatures and increased strain rates. This regime is referred to in the present work as hardening with …

Zur Texturentwicklung von gewalzten Seltenen-Erden-haltigen Magnesium-Knetlegierungen
… Wirksamkeit von Zener-Pinning (Ce und Nd) oder Solute-Drag (Y) gehemmt. Diese Veränderungen des Deformations- und Rekristallisationsverhaltens bewirken mit steigendem SE-Gehalt eine Abschwächung der starken Basaltexturen und die Anlage einer Querrichtungskomponente, was mit der Löslichkeit des …

Influence of grain size and niobium content on the creep resistance of ferritic stainless steels
… growth inhibition that arises from aspects of solute drag and grain boundary pinning. Thus it may not be simple to predict the relative creep resistance of standard production heats on the basis of Nb level alone and other factors affecting solid solution and grain size also need to be taken …

Effect of Dopants on the Local Atomic Structure and Sintering Behavior of Bismuth Sodium Titanate
… for densification. Possible reasons are the solute-drag effect and the pinning of domain walls by secondary phase particles. Both the depolarization temperature and the piezoelectric coefficient d33 decreased with increasing cobalt concentrations. The dielectric properties deteriorated as …

Advanced experimental measurements of heterogeneous strain and temperature change in metals
… The creep mechanisms were identified as solute drag for n and dislocation climb for n . Strain concentrations were identified at triple junctions and grain boundary serrations using high resolution digital image correlation overlaid on the microstructure. The grain boundary serrations …

The influence of rough rolling conditions on austenite evolution in peritectic microalloyed plate steels
… to the retardation of recrystallization by the solute drag of Nb. Pass strains of 0.15 promoted full recrystallization from the second pass onwards in all the studied steels and led to grain refinement of the austenite with a narrower grain size distribution. This was attributed to the increased …
