Popis:	Wire-based in-situ additive manufacturing (AM) technology is famous for the integration of material preparation and structure manufacturing. In the current study, the simulation method was adopted to study the thermal-stress evolution behavior during the process of the in-situ AM Ti-22Al-25Nb component. A single-layer multi-pass component was deposited firstly to prove the credibility of the simulation model. Then, the temperature-stress field evolution of the multi-layer single-pass component was revealed and analyzed systematically. This research is of great significance for suppressing the generation of cracks during forming process and promoting the wide application of Ti-22Al-25Nb alloys.
