Changes in Mechanical Properties Due to Heat Treatment on Additive Manufactured Ti-6Al-4V

Abstract

Laser-based additive manufacturing (AM) of Ti-6Al-4V has become increasingly important for use in components of transportation devices. The most significant advantage over conventional steel structures is the reduction in specific weight. Complex geometries can be produced with the layer-by-layer manufacturing process and the personalised, unique part production can be faster and produced with the lower costs and less material waste than the conventional manufacturing techniques. Between the manufacturing process of an additively manufactured part and its use, the post-processing is an essential factor related to the strength properties or porosity of the finished product. The heat treatment is a possibility to change the final part properties.
