Cast iron with 3 wt. % Cu was prepared by induction melting and casting in sand molds. The structure of the samples studied using light microscopy (LM), scanning electron (SEM) transmission (TEM). addition promoted formation pearlite slightiy decreased volume fraction graphite. No inclusions were found LM SEM. nanoprecipitations ε-Cu lamellar observed TEM. properties Cu-alloyed cast compared not alloyed Cu. hardness after alloying increased friction coefficient comparison reference sample.
In this study, Al21Co22Cr22Fe13Ni22 high-entropy coatings were produced on steel substrates by non-vacuum electron beam cladding of Co, Cr, and NiAl powders. The high-temperature oxidation behavior the was studied holding specimens at 900 °C in air. microstructure phase constitution samples both as-cladded state after heat treatment. characterized using light microscopy (LM) scanning (SEM). Synchrotron X-ray diffraction (SXRD) energy-dispersive spectroscopy (EDX) used to study...
In this study, we compare several peak profile analysis methods for the investigation of CoCrFeMnNi high-entropy alloy (HEA) after plastic deformation. We show that conventional Williamson - Hall (cWH) approach poorly correlates with measured broadening and some corrections must be introduced to improve analysis. The correction elastic modulus different crystallographic directions or application modified (mWH) Warren Averbach (mWA) significantly correlation between model experimental data....
NiAl-based intermetallic coatings were obtained using non-vacuum electron beam cladding on low-carbon steel. The structure of the was investigated optical microscopy, scanning microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), backscatter diffraction (EBSD), and (XRD). mostly consisted grains elongated perpendicular to substrates, with a strong <100> texture along grain growth direction. contained about 14 at. % Fe, which appeared due partial melting steel substrate. At...
Introduction. Vacancies are among the crystal lattice defects that have a significant effect on structural transformations processes during thermal, chemical-thermal, thermomechanical, and other types of alloys treatment. The vacancy formation energy is one most important parameters used to describe diffusion processes. An effective approach its definition based use density functional theory (DFT). main advantage this method carry out computations without any defined empirically. purpose...
Alumina-zirconia composites containing calcium hexaaluminate in the amount from 0 to 15 wt.% were investigated. The materials obtained by water dispersion, granulation, axial pressing, and free sintering. Density open porosity determined hydrostatic weighing method. Phase analysis was performed using synchrotron radiation. Structural investigations conducted scanning transmission electron microscopy. Vickers hardness at a load of 10 kg. Fracture toughness indentation With increasing...
