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 Ti43.3Y3.7Al15.3Co37.7 and Y38.8Ti12.8Al37.1Co11.3 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.
