The influence of the source material and the method of forming the object by layer-by-layer synthesis on the structure of the resulting product

Abstract

The article presents the studies’ results aimed at structure and properties learning of steel samples obtained by layer‑by‑layer application of structural material in the form of powder and wire. The ways that allow controlling the grain size in the formed products are given. It is shown that the structural products grinding manufactured by selective laser fusion can be achieved using powders obtained by reaction mechanical alloying and products formed by plasma and arc surfacing – by optimizing the conditions for applying layers.
