Abstract
X-ray absorption fine structure(XAFS) is used to investigate the local structural change of Fe60Cu40 and Fe80Cu20 with the ball milling time. The XAFS results verify that the solid solution of mechanically alloyed Fe-Cu samples are inhomogeneous. We propose that the bcc to fcc structural transformation of Fe small particles of Fe60Cu40(160h) is induced by interfacial Cu atoms dissolving in small Fe grain boundary during the mechanical alloying process.
