Originální abstrakt
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
