Abstract
Problem Statement. Additive technologies are a promising and developing branch of mechanical engineering, which makes it possible to produce metal products of final shape or close to final shape in one technological operation, which reduces production time and is economically feasible. Nowadays high-strength carbonless martensite-ageing steels of Fe-Ni-Co-Mo alloying system are widely used in high-tech branches of mechanical engineering and aerospace industry. Their use is due to the combination of properties that allow parts to be operated at extremely high and low temperatures, as well as under high impact and force loads. The most important advantage of martensite-ageing steels over other high-strength steels is their unusually high resistance to brittle fracture. In the production of heavy-loaded products of complex geometric shape from high-strength materials, one of the urgent tasks is the development of new cost-effective and high-performance technologies, such as additive manufacturing. In the case of growing products by arc surfacing method, the issues related to the reduction of anisotropy of the properties of the obtained material remain unsolved; the issue of adaptation of known heat treatment modes to ensure the required level and homogeneity of the specified properties also requires additional study. The purpose of the presented work is to study the regularity (features) of structure formation at macro- and microlevels of martensite-ageing steel samples obtained by additive growth with the use of subsequent heat treatment. Originality. The influence of heat treatment including homogenization, quenching and ageing on the formation of macro- and microstructure of martensite-ageing steel samples obtained by additive growth has been investigated for the first time. Results. The proposed heat treatment allows to achieve an increase in hardness and homogeneity of the deposited metal, which will favourably affect the operational properties of the deposited products.
