Abstract

Nowadays, additive manufacturing (AM) become very perspective method for fast fabrication of any details, parts or products. One of the main methods of AM is selective laser melting (SLM), which allows to obtain complex shape parts from various metal powders. However, this process requires high demands on the initial materials. To determine the quality of the initial EP648, EP741I, and Hastelloy X powders, such methods as scanning electron microscopy, laser diffraction, reductive melting and X-ray were used.
