Abstract
Coarsening kinetics of the equilibrium phase in the Al-rich end of the Al-Ti-Cu and Al-Ti-Ni systems have been studied using transmission el ectron microscopy as a function of annealing times at 698 K. The equil ibrium phase in the Al-Ti-Ni system coarsens at a rate that is 6 times faster than that in the Al-Ti-Ni phase. This difference in the coarse ning kinetics is related to the amount of mismatch of each of the equi librium phases with respect to the Al-matrix.
