Dynamic Shear Behaviour of Unweldable Aluminum-Scandium (Al-Sc) Alloy
This study uses a torsional split-Hopkinson bar to investigate the shear response and fracture characteristics of unweldable Al-Sc alloy during mechanical testing at shear strain rates of 800 s , 1500 s , 2200 s 1 and 2800 s 1 and temperatures of 150 C, 25 C and 300 C. The experimental results show that both the shear strain rate and the temperature have a significant effect on the shear proper...
متن کاملScandium effect on the luminescence of Er-Sc silicates prepared from multi-nanolayer films
Polycrystalline Er-Sc silicates (Er x Sc2-x Si2O7 and Er x Sc2-x SiO5) were fabricated using multilayer nanostructured films of Er2O3/SiO2/Sc2O3 deposited on SiO2/Si substrates by RF sputtering and thermal annealing at high temperature. The films were characterized by synchrotron radiation grazing incidence X-ray diffraction, cross-sectional transmission electron microscopy, energy-dispersive X...
متن کاملBis(μ-diphenylphosphanyl)bis[(trimethylphosphane)cobalt(I)](Co—Co)
The title compound, [Co2{P(C6H5)2}2(C3H9P)4], was obtained by the addition of di-phenyl-phosphane to a solution of Co(CH3)(C3H9P)4. The dinuclear complex mol-ecule exhibits inversion symmetry with the inversion centre located between the two Co(I) atoms. The short Co-Co distance of 2.3670 (8) Å lies within the range of metal-metal double bonds. As a result of inversion symmetry, the four-member...
متن کاملDosimetric Conformity of Cobalt-60 (Co) Beams
Objective: The radiation dosimetry is the output measurement of radiation generating source/ machine and its ambition is to ensure that the teletherapy units’ outputs are within limits. In the current article, the dosimetry of Cobalt-60 (Co 60 ) teletherapy units at Nuclear Institute of Medicine and Radiotherapy (NIMRA), Jamshoro Pakistan was studied. As Co 60 is undergo decay process, the outp...
متن کاملScandium(III) complexes of monophosphorus acid DOTA analogues: a thermodynamic and radiolabelling study with (44)Sc from cyclotron and from a (44)Ti/(44)Sc generator.
The complexation ability of DOTA analogs bearing one methylenephosphonic (DO3AP) or methylenephosphinic (DO3AP(PrA) and DO3AP(ABn)) acid pendant arm toward scandium was evaluated. Stability constants of their scandium(iii) complexes were determined by potentiometry combined with (45)Sc NMR spectroscopy. The stability constants of the monophosphinate analogues are somewhat lower than that of the...
