The combined effects of severe plastic deformation induced by high-frequency mechanical impact (HFMI) treatment and the electric discharge surface alloying (EDSA) with chromium on corrosion fatigue life low-carbon S355 steel transverse non-load-carrying specimens are studied in this paper. First, for various alternations HFMI + EDSA process, alloyed layer integrity depths were analyzed using scanning electron microscopy (SEM) accompanied energy dispersive spectroscopy (EDS) hardness...
Structural and thermo-activation analyses were carried out to reveal the creep rr ^nanisms for REfree magnesium alloys of Mg-Al, Ca, X Mg-Ba, systems eutectic origin containing light weight elements.To compensate useful RE effect in expensive prototypes, a family cheaper with cluster sites-forming structure is being developed higher temperature dynamical applications where low moment inertia, excellent stiffness high resistance time-dependent deformation are essential.At 150-250°C/50-70 MPa...
The effect of cold plastic deformation by upsetting (e = 1.13) on structure and hybridised bonds carbon in the fcc Invar Fe-30.9%Ni-1.23% C alloy was studied means X-ray phase analysis photoelectron spectroscopy. Carbon precipitates along grain boundaries inside grains after annealing were revealed. presence mainly sp2- sp3-hybridised C–C attributing to graphite amorphous as well with impurity atoms metallic Fe Ni austenitic revealed annealed deformed alloy. It shown for first time that...
УкраинаВ работе рассмотрено влияние скоростей нагрева и охлаждения материалов подложек из меди нержавеющей стали на структуру ионноплазменных покрытий, полученных методом КИБ -осаждения продуктов дугового распыления катода, изготовленного механическим способом слитка высокоэнтропийного сплава AlCuCoFeNiCr эквиатомного состава.Структуру материала катода покрытий исследовали с помощью оптической электронной микроскопий, а также рентгеновской дифрактометрии.Установлено, что полученные покрытия,...
The physical vapor deposition by cathode arc evaporation (PVD CAE) technique in microdrops mode was applied for of austenitic nanocrystalline coatings the Fe−31.2%Ni−2%Co−0.002%Y and Fe−31.4%Ni−2%Co−0.72%C−0.001%Y alloys on Cu substrate. Mössbauer spectroscopy, X‐ray diffraction analysis, transmission electron microscopy dilatometry have been used to study structure, magnetic order thermal expansion coatings. estimated coherently diffracting domains values (CDD) TEM data testify that...
