【 摘 要 】

Today, when manufacturing and restoring bulk products of almost any shape and complexity degree, additive technologies are in demand, which use metal-powder compositions of various alloys as a building material. In the present work, the possibility of obtaining powder by gas atomization from batch products of high-nitrogen 04Cr20Ni6Mn11Mo2NVNb steel used for selective laser melting is shown, its structure and properties are evaluated.
