The successful joining of oxide dispersion-strengthened (ODS) alloy PM2000 rods by pulsed plasma-assisted diffusion bonding is reported. During secondary recrystallization after joining, the alloy grains grew across the original interface, which was then marked by a row of remnant alumina particles. These did not appear to act as pinning sites for the alloy grain boundaries, which moved easily past them, leaving a strong diffusion bond.
