Abstract
Titanium (Ti) based lightweight alloys are widely known in aerospace and medical applications due to their advantageous properties, such as low density and high strength. However, Ti has a high affinity for oxygen, which leads to difficulties during production. Therefore, the cost of production is considered to be high. This represents a major challenge in the production of large-sized components.
In this presentation, newly developed wire-based laser deposition welding process to produce Ti-based components with a high build-up rate of more than 150 cm3 / h is presented. The process is carried out in pre-vacuum (10-3 mbar) with pre-heating of the wire-shaped raw materials. The microstructure and the mechanical properties of Ti-based printed components at both room temperature and high temperatures were characterized and tested. The results obtained show a very low oxygen content with less than 0.002% by weight. The tensile strength of the Ti-based printed components using this new process is higher comparing to the conventional manufactured Ti-components at high temperatures.
