Abstract

X-ray diffraction and scanning electron microscopy were used to monitor the mechanical alloying of four different mixtures of cobalt and boron with atomic compositions Co50B50, Co67B33, Co75B25 and Co80B20, respectively. The process induces amorphization reactions depending on the boron content; an almost complete amorphization was reached for the Co67B33 and Co80B20 samples, where only minor traces of unreacted cobalt are present. Extended X-ray absorption fine structure data collected on the most amorphous sample confirmed the diffraction results. In all the samples, the formation of t-Co2B was detected.
