摘要：
The main purpose of this work is to utilize EXAFS to observe the atomic-scale structural changes during the MA (mechanical alloying) process of two Fe-B powder mixtures: one is Fe80B20 (which is amorphized by RQ, 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 atoms into the alpha-Fe crystal was observed. Contrary to this, in the MA process of Fe80B20, the B atom dissolution into the alpha-Fe crystal was not observed.
