Abstract
The main purpose of this work is to utilize EXAFS to observe the atomi c-scale structural changes during the MA (mechanical alloying) process of two Fe-B powder mixtures: one is Fe80B20 (which is amorphized by R Q, but not by MA) and the second is Fe50B50 (which is amorphized by MA , but not by RQ). In the MA process of Fe50B50, the dissolution of B a toms into the alpha-Fe crystal was observed. Contrary to this, in the MA process of Fe80B20, the B atom dissolution into the alpha-Fe crysta l was not observed.
