摘要
The powder of Nb-25Ti-2Cr-2Al-16Si (at%) was obtained by mechanical alloying and plasma spheroidization from elemental powders. The building was performed by SLM 280HL machine on the titanium substrate. The microstructure was analyzed by MIRA Tescan scanning electronic microscope. The XRD was performed by BRUKER D8. The microstructure consists of Nbss+Nb3Si eutectic with several areas of coarse dendrites, corresponds to the Nbss. The microstructure is greatly refined in comparison with casting technologies like VIM.
