“…In this case, elements show no mutual solubility at room temperature and, therefore, the equilibrium microstructure is composed of separated phases of two pure elements. This allows preparing materials with an interesting combination of properties such as high strength and high electrical conductivity or superior magnetic properties [4][5][6][7] that is difficult to achieve with common materials. In addition, it is possible to alloy a selected phase by elements miscible with one of the basic components and immiscible with the second one, which allows control the resulting microstructure and tailor the mechanical properties [8][9][10].…”

The immiscible Cu-Fe system is often used as a base for new advanced alloys. In the current study, three batches of the same immiscible (Cu70Fe15Co15)89W11 alloy were prepared by mechanical alloying with different milling time and subsequent SPS consolidation. The effect of milling time on the microstructure and the properties of the powder and bulk samples was subject to study. The microstructure of the milled powder samples consists of FCC Cu-based supersaturated solid solution and particles of pure W, which did dissolve only partially. During the SPS consolidation, Cu-based supersaturated solid solution partially decomposed and (Fe, Co)-based solid solution, (Fe, Co)7W6 phase, and pure Cu phase were formed. Increasing the milling time results in the finer microstructure of the consolidated samples and in the enhancement of their hardness. The maximum hardness achieved is 395HV1. The longer milling time has a negative effect of decrease in relative density of consolidated samples, caused by larger size of the milled powders.

This present work concerns the effect of ternary addition of non‐metallic and diamagnetic silicon on the metastable solubility of the immiscible silver‐cobalt system during the course of ball milling, annealing of the ball milled samples and the corresponding magnetic properties. It should be noted that silicon has a smaller goldsmidt radius (111 pm) than silver (144 pm) and silicon+4 has more valence electrons than silver+1. Keeping the objectives of the current study in mind, silicon may thus be considered as an option for ternary addition, in contrast to metallic components. An attempt has been made to examine the phase changes that occurred in the 50 silver‐40 cobalt‐10 silicon (atom percent) system during ball milling and the subsequent isothermal annealing of the ball milled product. Phase evolution during mechanical alloying and isothermal annealing is identified by means of x‐ray diffraction, differential thermal analysis, high resolution transmission electron microscopy and magnetic measurements. The addition of silicon facilitates cobalt‘s formation of a metastable alloy with copper after 50 hours of ball milling. Annealing significantly improves the magnetic characteristics of materials that have been ball milled; the optimal combination of magnetic properties was obtained after an hour of annealing at 550 °C.
