    Abstract

    Displacement spike annealing computer experiments were done for body-centered cubic (bcc) and face-centered cubic (fcc) iron using five different annealing models. Each model predicted a greater number of free interstitials than free vacancies. The number of annihilation events was increased by an increase in cluster migration and decreased by an increase in the clustering interaction radius. The largest number of surviving defects occurred when clusters of four or more defects were immobile and a small clustering interaction radius was assigned.
