Formation of Structure in Titanium Lightweight Structures Made by Selective Laser Melting

Article Preview

Abstract:

The results of the analysis of the plasma atomized powder material are shown. An analysis of the microstructure in lightweight constructions made of VT6 alloy by selective laser melting was carried out. The microstructure and mechanical characteristics of the obtained structures were studied before and after heat treatment. Measurement of grain size in the microstructural analysis gave a more complete picture of the state of the structure in different parts of the sample formed as a result of growing by selective laser melting, in a mesh and compact. In the course of the work, the peculiarities of the growth of grains in bars of the mesh construction are revealed depending on their location.
