Suppression of vortex channeling in meandered YBa2Cu3O7-d grain boundaries

open access: yes, 2007
We report on the in-plane magnetic field (H) dependence of the critical current density (Jc) in meandered and planar single grain boundaries (GBs) isolated in YBa2Cu3O7-d (YBCO) coated conductors.

Using reference materials of blast furnace slag, steelmaking slag, converter slag and fused fluxes when developing a procedure for analysis of slag-forming mixtures using inductively coupled plasma atomic emission spectrometry

open access: yesСтандартные образцы, 2018
Introduction. Slag-forming mixtures play an important role in obtaining metal without non-metallic inclusions. Required properties of slag-forming mixtures (SFMs) directly depend on their chemical composition, that is why control of individual component ...

Flux penetration and a.c. losses in type II superconductors : II. Experiments on Nb-50% Ti [PDF]

open access: yes, 1982
The a.c. behaviour of Nb-50% Ti can be described in terms of the quasi-static Critical State Model. The critical current density jc as a function of position and magnetic induction as well as the Ben(Ba) and Bex(Ba) relations which described the surface ...

Low temperature vaporisation of Cr from fluoride flux reacted at 1350 °C with Al–Cr–Fe powder: Thermochemical analysis of gas phase reactions and nano-strand formation

open access: yesJournal of Materials Research and Technology
The submerged arc welding (SAW) process is complex because multi-phase reactions occur simultaneously across a large temperature interval from 2500 °C in the arc cavity, down to the weld pool liquidus temperare at the slag-weld pool interface.

Beneficiation of concentrated ultrafine suspensions with a Falcon UF concentrator [PDF]

open access: yes, 2011
Falcon concentrators are enhanced gravity separators designed for concentrating fine particles. The Falcon UF model is unique in that it is dedicated to beneficiation of ultrafines, one key feature being that it does not make use of any fluidization ...

Assessing the impact of carbonitriding on residual weld hydrogen in the manufacture of a gear component

open access: yesJournal of Materials Science: Materials in Engineering
In this paper, we report on the direct measurement of hydrogen flux from a machined car gear component immediately following carbonitriding treatment and prior to its welding to the gear train.

On the effect of Ti on Oxidation Behaviour of a Polycrystalline Nickel-based Superalloy [PDF]

open access: yes, 2018
Titanium is commonly added to nickel superalloys but has a well-documented detrimental effect on oxidation resistance. The present work constitutes the first atomistic-scale quantitative measurements of grain boundary and bulk compositions in the oxide ...
