Kinetic study of static recrystallization in an Fe-Al-O ultra-fine-grained nanocomposite

Popis výsledku v původním jazyce

A nearly abrupt coarsening of grains is observed in a newly developed Fe-Al-O ultra-fine-grained nanocomposite with a significant volume fraction (4%) of alumina nano-precipitates. The microstructure of the alloy was analysed in different states (as-received and annealed) by means of scanning electron microscopy, transmission electron microscopy (TEM) and hardness. The initial grain size 150-200nm increases up to 50m during annealing 1000 degrees C/8h and thereafter demonstrates saturation. A linear correlation between volume fraction of coarse grains and hardness was found. It was identified by TEM that alumina nano-precipitates stabilize the dislocation microstructure against recovery very effectively and the grain coarsening is due to fast growth of very few dislocation free grains. Thus, the observed grain coarsening has the attributes of static recrystallization.
