“…Formation of Ag-rich areas was also observed in a rapidly solidified Ag 20 Cu 30 Ti 50 alloy [27]. It may lead to an increase in the sample size owing to the formation of two phases with different specific volume.…”

“…705 HV and 130.03 GPa, respectively. The higher values of hardness number and Young modulus can be explained by the fact that these values for crystalline microstructures are generally on the higher level than found in the corresponding amorphous state [19]. Assuming that the melt-spun Ag 20 Cu 30 Ti 50 alloy is an amorphous/crystalline composite, where the volume fraction of the crystalline Ag-base phase is 21%, Young modulus of the crystalline Ag-rich phase is equal to the value measured above for Ag-base phase in arc-melt sample, i.e.…”

“…The Ni-Fe-Cu-P system provides the glass forming alloys [15][16][17][18][19], on the other hand a relatively high positive enthalpy of mixing between Fe and Cu [20] justify the expectation that for some compositions liquid miscibility gap can be observed in the Ni-Fe-Cu-P system. The aim of the work is to investigate the range of the glass forming compositions in a series of alloys Ni 80-2x Cu x Fe x P 20 , where x = 5, 10, 15, 20, 25 and 30.…”

The aim of the work is to study the ability and potential of glass formation in Ni-Fe-Cu-P alloys. A series of alloys were produced in arc furnace (i.e. Ni 70 . The primary microstructure of the ingots was studied. The ribbons in as-melt-spun state were characterized by X-ray diffraction (XRD). The Ni 70 Fe 5 Cu 5 P 20 , Ni 60 Fe 10 Cu 10 P 20 melt-spun alloys were found to be amorphous. For higher copper and iron concentrations a crystalline structure was obtained after melt spinning. This correlated with the tendency for the formation of the Fe-based phases enriched in P and Cu-based poorly alloyed phases which resulted in the formation of crystalline microstructure in melt-spun ribbons. For higher concentration of Fe and Cu, microstructures of the alloys contained constituents resultant from a tendency for separation in the liquid state. It is observed that the formation of the crystalline melt-spun ribbons is caused by the attraction of phosphorus by iron and the formation of copper-based fcc phase. Key words: amorphous materials, amorphization, X-ray diffraction, transmission electron microscopy Streszczenie Celem pracy było zbadanie podatności na zeszklenie oraz możliwości wytworzenia struktury szklistej w stopach wieloskładnikowych Ni-Fe-Cu-P. P 20 odlewane na wirujący bęben były amorficzne. Dla stopów o wyższych zawartościach miedzi i żelaza po odlewaniu na wirujący walec otrzymano strukturę krystaliczną. Fakt ten można powiązać z tendencją do tworzenia faz na osnowie żelaza wzbogaconych w fosfor oraz zubożonych w pozostałe składniki stopowe faz na osnowie miedzi, które przyczyniły się do tworzenia w odlewanych taśmach mikrostruktury krystalicznej. Dla wyż-szych zawartości żelaza i miedzi, mikrostruktury stopów zawierały składniki fazowe powstające w efekcie tendencji stopów do podziału fazowego w stanie ciekłym. Zaobserwowano, że tworzenie krystalicznych taśm jest spowodowane przez przyciąganie fosforu przez żelazo oraz tworzenie bogatej w miedź fazy o strukturze regularnej ściennie centrowanej. Słowa kluczowe: materiały amorficzne, amorfizacja, dyfrakcja rentgenowska, transmisyjna mikroskopia elektronowa
