Title: Pulsed Plasma-Assisted Diffusion Bonding of ODS-FeCrAl Alloys

Abstract

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