DIFFUSION AND AGING IN Cu Fe ALLOYS

open access: yesLe Journal de Physique Colloques, 1979
Mössbauer spectroscopy has proved of value both in quantitative studies of iron diffusion in CuFe alloys at room temperature and in qualitative analysis of the aging processes at higher temperature. Spectra obtained dynamically at 400°C have enabled the development of γ-Fe precipitates from Fe clusters to be studied in detail.

On the Mechanical Properties of Cu-Fe Alloys

open access: yesDENKI-SEIKO[ELECTRIC FURNACE STEEL], 1973
Mechanical properties, metallurgical structures and fiber textures of Cu-Fe alloys were investigated and the following results were obtained.(1) The quenched Cu-Fe alloys are harder than the slowly cooled Cu-Fe alloys after holding at the temperature range over the eutectic point, and the faster the cooling rate is, the larger the difference of ...
