Thermal treatment of 3D-printed Titanium alloy

Popis výsledku v původním jazyce

In metals processing, 3D printing is a relatively new technology. It brings many advantages into production thanks to its additive principle on which it is based. One of the intended applications of 3D printing is especially regenerative medicine and aerospace industry that require products of very complex shapes. In these domains, titanium along with its alloys belongs among the most frequently used materials. When printing a Ti6Al4V alloy, very high cooling rates during the successive laser melting of an initial powder material result in high internal stresses. These stresses are followed with several problems, such as low material plasticity, possible cracking of built products, deformations of thin parts and similarly. Therefore, after the 3D printing process itself, a thermal treatment is applied to relief the stresses. The object of this study is to show the influence of atmosphere in thermal treatment process on the quality of final parts. The results show that oxygen absence is essential in terms of material plasticity. © 2018. Published by Manufacturing Technology.
