Nowadays titanium alloys are widely used for building various parts for the aeronautical or aerospace industries, in the energy field, petroleum industry, in medicine and recently in the automotive industry, the sporting goods industry, etc. In this paper is analysed the influence of the heat treatment on the microstructure and compressive strength of the TiAl6V4 alloy samples, having a Lattice structure. The analyses results indicate differences between the as-built samples and the heat-treated samples. In this regard, heat-treated samples have a much uniform and stabile structure, a micro-structure with fewer pores and better mechanical resistance to compression stress. These results confirm that the heat treatment favourably influences the microstructure of the samples, reduces the internal stress and their mechanical characteristics too.
