Abstract

A porous Ti-based metallic glass has been fabricated by applying the principle of dealloying to the Y₂₀Ti₃₆Al₂₄Co₂₀ two-phase amorphous alloy. The initial microstructure of the two-phase glassy alloy consisted of Ti_43.3Y_3.7Al_15.3Co_37.7 and Y_38.8Ti_12.8Al_37.1Co_11.3 amorphous phases forming an interconnected structure. To fabricate the porous structure, the Y-rich phase has been selectively dissolved from the alloy using both chemical and electrochemical treatments in 0.1 M HNO₃ solution. The glassy nature of the porous Ti-based alloy was confirmed by transmission electron microscopy analyses.
