Sažetak
The formation of transition metal compounds (TC) in selected devitrified high-entropy (HE) and conventional metallic glasses (MG) has been studied by using X-ray diffraction (XRD) and magnetic susceptibility (χ) measurements. The alloys selected were Al0.5TiZrPdCuNi [1], (TiZrNbL)1-xMx (L = Cu, Ni ; M = Fe, Co, Ni, Cu) [2] HEMGs, as well as conventional binary and ternary MGs containing early (TE) and late (TL) transition metals, such as the Ti, Zr, Hf – L [3] and Zr-Cu-Al alloys. Such study provides a comparison between the crystallization patterns in TE-TL HEMGs and these in conventional MGs with the same constituents, which can help to understand the differences in glass forming ability (GFA) between HEMGs and conventional MGs [2, 3]. The measurements of χ on both as-cast and crystallized alloys provide an insight into the changes of electronic structure (ES) accompanying transition from amorphous to crystalline (TCs) state, which seem to determine GFA of TE-TL alloys [3]. Further, the values of χ for crystallized alloys, χc, enable in principle the determination of χc values corresponding to particular TCs. These χc (TC) values in addition to giving an insight into contribution of given TC to ES also enable the determination of the fractions of TCs in a given alloy. This is important for a quantitative analysis of the phase contents in alloys in which the crystalline texture make the determination of phase contents from XRD less accurate. Wherever possible we compare and combine our data with the results from literature. _____________________________________________ ∗ This work was supported by UNAM-DGAPA-PAPIIT project No. IN101016 and Osijek University project IZIP2016-3. † [1] A.
