Polozov, Igor (author), Kantyukov, Artem (author), Popovich, V. (author), Zhu, Jia Ning (author), Popovich, Anatoly (author)Additive Manufacturing (AM) is an attractive way of producing parts of intermetallic titanium alloys. However, high brittleness of these alloys makes it challenging to produce crack-free intermetallic parts by AM. One way to overcome this problem is to use high-temperature powder-bed preheating. In this paper, Ti-48Al-2Cr-2Nb alloy was...conference paper 2020
