“…It is well known that the relatively high enthalpies of mixing between the elemental constituents of the alloy correlate well with its good glass forming ability. For Ni-Cu-Fe-P system all of the metallic elements fulfill the condition with relation to P. It is also well known that there are a number of both Ni-based and Cu-based amorphous alloys with phosphorus [22][23][24][25]. However, in the present work it is shown that a sufficiently high content of Ni in the alloy and relatively low Fe and Cu content cause that the latter two elements are diluted enough in Ni-P liquid and there is no partitioning in the liquid state in spite of the relatively high positive enthalpy of mixing between Fe and Cu.…”

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
