THE SIGNIFICANCE OF METALLIC TRANSFER IN ORTHOPAEDIC SURGERY [PDF]

open access: yesThe Journal of Bone and Joint Surgery. British volume, 1955
1. Experiments using radio-isotope techniques show that whenever an orthopaedic appliance is inserted into the body tiny fragments of the instruments used to handle it become detached and welded on to the surface of the buried metal. 2. There is evidence that these particles of non-passive tool-metal may cause a small but continuing dissolution of ...

Heat transfer enhancement for thermal energy storage using metal foams embedded within phase change materials (PCMs) [PDF]

open access: yes, 2010
In this paper the experimental investigation on the solid/liquid phase change (melting and solidification) processes have been carried out. Paraffin wax RT58 is used as phase change material (PCM), in which metal foams are embedded to enhance the heat ...

Transition Metal Substitution Effects on Metal-to-Polyoxometalate Charge Transfer [PDF]

open access: yesInorganic Chemistry, 2016
A series of hetero-bimetallic transition metal-substituted polyoxometalates (TMSPs) were synthesized based on the Co(II)-centered ligand [Co(II)W11O39](10-). The eight complex series, [Co(II)(M(x)OHy)W11O39]((12-x-y)-) (M(x)OHy = V(IV)O, Cr(III)(OH2), Mn(II)(OH2), Fe(III)(OH2), Co(II)(OH2), Ni(II)(OH2), Cu(II)(OH2), Zn(II)(OH2)), of which six are ...

Numerical study on conjugate heat transfer in a liquid-metal-cooled pipe based on a four-equation turbulent heat transfer model

open access: yesNuclear Engineering and Technology, 2023
Conjugate heat transfer between liquid metal and solid is a common phenomenon in a liquid-metal-cooled fast reactor's fuel assembly and heat exchanger, dramatically affecting the reactor’s safety and economy.

Microstructural Analysis of Friction Stir Butt Welded Al-Mg-Sc-Zr Alloy Heavy Gauge Sheets

open access: yesMetals, 2020
Friction stir welding (FSW) on a heavy gauge sheet of a hereditary fine-grained Al-Mg-Sc-Zr alloy was carried out to study the specifics of plasticized metal flow and microstructural evolution in different sections and zones of the joint.

Characterisation of the cold metal transfer (CMT) process and its application for low dilution cladding [PDF]

open access: yes, 2011
The process characteristics of the synergic cold metal transfer (CMT) process have been examined for welding aluminium alloy. Utilising a simple backlighting system and through the arc monitoring the droplet transfer modes were identified.
