摘要
Experiments were carried out on the post-dynamic coarsening of alpha and reverse transformation of Ti-6Al-4V. The post-dynamic coarsening followed rnvs time kinetics and the n = 3 best fit indicated that it was controlled by bulk diffusion, i.e., by vanadium diffusion through the beta matrix. Its rate was one order of magnitude faster than that applicable to static coarsening. The reverse transformation was characterized using a compression dilatometer and occurred in two stages; the first was transformation on dislocations; the second involved the growth of the alpha structure.
