► Impact of micro-jets mechanically breaks the oxide film on the Ti–6Al–4V surface at numerous tiny locations. ► Solid Ti–6Al–4V is excessively dissolved into liquid Al–Si under the effects of hot spots and ultrasonic stir. ► Different intermetallic compounds (TiAl3 and Ti7Al5Si12) form at different...
