Effect of building direction on the microstructure and tensile properties of Ti-48Al-2Cr-2Nb alloy additively manufactured by electron beam melting
Mitsuharu Todai,Takayoshi Nakano,Tianqi Liu,Hiroyuki Y. Yasuda,Koji Hagihara,Ken Cho,Minoru Ueda,Masao Takeyama +7 more
TL;DR: In this paper, the authors clarified a novel strategy to improve the tensile properties of the Ti-48Al-2Cr-2Nb alloys fabricated by electron beam melting (EBM), via the finding of the development of unique layered microstructure composed of duplex-like fine grains layers and coarser γ grains layers.
