Abstract: Ti–6Al–4V alloy was joined with TiB2–Ni cermet by using pulsed current heating and hot pressing. The properties were found to be better with the pulsed current process, because the current enhanced the growth of Ni–Ti phase at the junction between the two materials. Furthermore, the heat affected zone is localised in the pulsed current process relative to that in the hot pressed material. [ABSTRACT FROM AUTHOR]
