Structural Transformation of Immiscible Metals Induced by Mechanical Alloying
1997
Journal de Physique IV : Proceedings
Preserved Fulltext
X-ray absorption fine structure(XAFS) is used to investigate the local structural change of Fe60Cu40 and FegoCu20 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 Fe60Cuq0(160h) is induced by interfacial Cu atoms dissolving in small Fe grain boundary during the mechanical alloying process.
