Powder Fraction

One of the disadvantages of using steel powders is the difficulty of producing such materials. In this article, steel powders from various manufacturers were discussed. The analysis of the surface, powder particles and the distribution of the fractional composition and the possibility of reuse was carried out. Direct laser deposition modes, using different laser power, were designed. From the obtained modes, tensile and impact bending samples were grown, and a comparative analysis of the obtained results was carried out.

Review focuses on describing of mechanical properties of the components manufactured via direct laser depositionfrom cold resistant steel material. The results of tensile and impact testing are presented and microstructures of the fractures are shown. The process of laser deposition of cold-resistant steels, the formation of structures, as well as the mechanical properties of these samples are poorly understood. The results of tensile and impact tests are presented, and microstructures are shown. Mechanical tests for impact strength were carried out at a temperature of -40˚С, with different laser radiation powers. The results are given using the as-received powder, as well as used powder with a different mixing ratio, and the results are analyzed. As a result of the study, it was found that the fractional composition of the 09XH2MD alloy powder affects the mechanical characteristics of samples obtained by direct laser deposition. The effect of recycled powder on the mechanical properties of the obtained samples is given, the optimal laser deposition regimes are selected
