AbstractLinear homogenization is applied to cellular structures produced by selective laser melting (SLM). Samples of different materials with cells of different configurations are studied theoretically and experimentally. Their strain curves are compared with the results for bulk and beam models and with experimental data. After homogenization, th...

AbstractThe melting of strips resembling the crosspieces in cellular structures is studied experimentally. The results permit the identification of technological conditions yielding stable samples with uniform surface structure and minimum geometric divergence from the 3D model. On the basis of geometric modeling, a method is proposed for the produ...

AbstractThin-film vacuum technology permits the creation of new electrode materials on the basis of a flexible carbon matrix with a highly developed surface. Supercapacitor structures, pseudocapacitor structures, and hybrid structures have been produced and studied with a view to smart power storage and transportation.

AbstractPrediction of part technological distortions on the basis of the computer simulation of additive manufacturing (selective laser melting) is considered. The modeling results are compared with experimental data. By simulation, the influence of the part’s position and the number of supports on its technological distortions is determined. Disto...

AbstractThe influence of the parameters of spark plasma sintering on the structural evolution within composites consisting of a superalloy, binder, and a zirconium-oxide ceramic is studied, as well as the associated processes at the layer boundary. The behavior of the phase composition, distribution of the elements, and micromechanical characterist...
