In the present work, Cu-1.35Ni-1Co-0.55Si alloy with multiple twins and ultra-low interfacial mismatch precipitates was obtained by liquid nitrogen dynamic plastic deformation (DPD) aging treatment. It has abnormally high work hardening ability, which is more than twice that of previous DPD treatment without aging. addition, it excellent comprehensive properties, its strength, electrical conductivity, elongation are 816.4 MPa, 40.2% IACS 11.3% respectively. The fine do not coarsen...
Although tremendous efforts have been devoted to the exploration of cost-effective, active, and stable electrochemical catalysts, only few significant breakthroughs achieved up now. Therefore, exploring new catalysts improving catalyst activity stability are still major tasks at present. Controllable synthesis Pt-based alloy nanocrystals with a uniform high-index surface unique architecture has regarded as an effective strategy optimize their catalytic efficiency toward reactions....
In this study, the effects of differences in grain size, boundary type and misorientation on initiation discontinuous precipitates are investigated for Cu-5Ni-1.25Si alloy. Samples with different sizes obtained by thermomechanical treatment, smaller higher percentage precipitate at same aging time, while there is no significant difference growth rate reaction front precipitates. EBSD used to study effect precipitates, characteristics boundaries multivariate statistical analysis. It found...
Twins play a crucial role in elucidating the structure and deformation characteristics of materials. However, materials with low-symmetry crystal structures, solving twin relationships remains challenging task. In this study, we propose general method for determining elements K1, η1, K2, η2, which are essential analysis. The proposed involves three main steps: (1) representing misorientation data measured by electron back-scattered diffraction (EBSD) transmission microscopy (TEM) matrix...
Coarse particles in Cu-0.39Cr-0.24Zr-0.12Ni-0.027Si alloy were studied with scanning electron microscopy and transmission microscopy. Three types of coarse determined: a needle-like Cu5Zr intermetallic phase, nearly spherical Cr9.1Si0.9 phase (Cu, Cr, Zr, Ni, Si)-rich lath complex particles. The crystallographic orientation relationships the also determined. reasons for formation role phases Cu-Cr-Zr alloys are discussed, some suggestions proposed to control alloys.
Amorphous and crystalline Zn[Formula: see text]Co x S ([Formula: text], 0.3, 0.5) thin films were grown on sapphire (Al 2 O 3 ) substrates by pulsed laser deposition at substrate temperature of 25 ∘ C 800 C, respectively. The X-ray diffraction results show that the film has a cubic zinc blende structure quality decreased with increasing Co-doping concentration. photoelectron spectroscopy spectra reveal samples reached an overdoping state concentration [Formula: text]. absorbance increases...
