Fig. 1. X-ray diffraction scan showing kinetic disordering
of intermetallic compound Ni3Al, which in equilibrium is ordered
all the way up to its melting point, by pulsed laser melting and
rapid solidification. Superlattice peak (220) disappears after laser
treatment while fundamental peak (110) remains, showing that the material
has been kinetically disordered. Long-range order is recovered with
a subsequent furnace anneal.
