  • Неразрушающий контроль качества термообработки стальных образцов, полученных аддитивной технологией, магнитошумовым методом 

    Бусько, В. Н.; Крень, А. П.; Ланцман, Г. А. (БНТУ, 2022)
    Производство изделий по аддитивным технологиям, как правило, сопровождается несанкционированным появлением и ростом неоднородности свойств, анизотропии, остаточных напряжений, пористости и других дефектов. Поэтому резко возросла актуальность неразрушающего контроля качества изделий, полученных с помощью аддитивных технологий. Цель работы – экспериментально исследовать возможность ...

  • Tensor Calculus in Digital Colorimetry 

    Saukova, Y.; Hundzina, M. (БНТУ, 2022)
    Any object can have many implementations in the form of digital images and any digital image can be processed many times increasing or decreasing accuracy and reliability. Digital colorimetry faces the need to work out issues of ensuring accuracy, metrological traceability and reliability. The purpose of this work was to generalize approaches to the description of multidimensional ...

  • Non-Additive Quantity Measurement Model 

    Romanchak, V. M.; Serenkov, P. S. (БНТУ, 2022)
    This work considers a model for measuring non-additive quantities, in particular a model for subjective measurement. The purpose of this work was to develop the measurement theory and form of a measurement model that uses the corrected S. Stevens measurement model. A generalized structure was considered that included an empirical system, a mathematical system, and a homomorphism ...

  • Spectral Ellipsometry as a Method of Investigation of Influence of Rapid Thermal Processing of Silicon Wafers on their Optical Characteristics 

    Solodukha, V. A.; Pilipenko, U. A.; Omelchenko, A. A.; Shestovski, D. V. (БНТУ, 2022)
    One of the possible ways of improvement of the surface properties of silicon is the solid phase recrystallization of the surface silicon layer after the chemical-mechanical polishing with application of the rapid thermal treatment with the pulses of second duration. The purpose of the given paper is investigation of influence of the rapid thermal treatment of the initial silicon ...

  • Calculation of Correction Factors for Vickers Hardness Measurements on a Non-Planar Surface 

    Sandomirski, S. G.; Val’ko, A. L.; Rudenko, S. P. (БНТУ, 2022)
    The exact determination of Vickers HV hardness is important for determining of the product material mechanical properties. An important aspect of measuring HV is to obtain its values on a non-planar surface. Regulatory documents contain table values of correction factors K which depend on the surface shape (convex or concave, spherical or cylindrical), its curvature (diameter D) ...

  • Correction of the Contribution of Scattered Photon Radiation to the Ionization Chamber Readings During X-Ray Radiation Quality Assessment 

    Zaharadniuk, A. A.; Senkovsky, K. G.; Lukashevich, R. V. (БНТУ, 2022)
    Reduction of the systematic error when determining the characteristics of the reference X-ray radiation fields is an essential task according to the ISO 4037-1:2019 standard. This task is especially important in dosimetry laboratories when establishing the qualities of reference photon fields. The aim of the study was to develop a method that allows taking into account the ...
