摘要：

Utilizing57Fe and119Sn Mössbauer spectroscopy, the microscopic behavior of metallic powders has been investigated during and after the mechanical alloying (MA) process. A conventional ball-milling method is employed and the following combinations of metallic powders have been studied for their MA; Al-Fe, Fe-Sn and Ag-Fe. Mössbauer spectra show the occurrence of mutual atomic dispersion during the MA process even for the Ag-Fe system which is known as mutually immissible even in the liquid state. Formation of an amorphous phase in the Al-Fe system has been detected. © 1990 J.C. Baltzer A.G. Scientific Publishing Company.
