Role of Si on lamellar formation and mechanical response of two SPS Ti–15Al–15Si and Ti–10Al–20Si intermetallic alloys
Original language description
Two TiAlSi intermetallic compounds produced by Spark Plasma Sintering (SPS) adding different Si content were tested by nanoindentation, toughness and wear resistance. Microstructure differences between the two alloys were characterized by TEM and a strengthening model was proposed. The microstructure-based strengthening model well agreed with alloys stress obtained from the nanoindentation hardness. It resulted that as Si content increases, the TiAl phase started to form lamellar structure and inter-lamellar twinning. Al reduction in favour of an equal amount of Si was found to slightly promote Ti5Si3 silicide formation and eventually a TiAl phase coarsening. Ti–15Al–15Si alloy showed submicrometric equiaxed TiAl grains. On the other hand, Ti–10Al–20Si alloy was characterized by a lamellar TiAl phase which was identified as responsible for the different mechanical responses of the two alloys. © 2021 Elsevier Ltd
