Effects of Cold-working and Annealing on the Resistivity Minimum of some Dilute Cu-Fe Alloys
Abstract
Changes in the temperature at which the resistivity minimum occurs have been studied in dilute Cu-Fe alloys in different quenched, coldworked and annealed states. The effects observed are thought to be caused by clustering tendencies of the iron atoms in the matrix affecting the scattering process. The connection between the temperature of the resistivity minimum and the Fe concentration empirically derived by Knook [3] for very dilute Cu-Fe alloys is shown to hold reasonably well for quenched alloys at Fe concentrations below about 0.85 at% while for alloys of higher concentrations the temperature of the resistivity minimum decreases with increasing Fe content. In the latter case intense cold-work is shown to cause an increase of the temperature of the resistivity minimum whereas annealing processes lower the same temperature.
