PRESSURE DEPENDENCE OF THE RESISTIVITY OF AMORPHOUS NiZr ALLOYS

Structure property relationship in (TiZrNbCu)1−xNix metallic glasses

“…For the sake of completeness, in what follows we briefly summarize some results of an ongoing study of the electronic transport properties of our alloys [81]. As is usual in a-TE-TL alloys [38], the electrical resistivities  of a-(TiZrNbCu)1-xNix alloys are high (>150 µcm) and accordingly decrease with increasing temperature over most of the explored temperature range (T≤300K [89,90], for Zr-Ni from [89,91], for Ti-Cu from [88,92,93] and Ti-Ni from [90]. Dashed lines are guide for eye.…”

“…We note that such a simple relationship between the electronic structure and interatomic bonding is quite common in crystalline alloys and in nonmagnetic a-TE-TL alloys it probably stems from their simple electronic band structure [64]. In Figure 8 we compare the variations of E of our relaxed samples, that have received a short anneal close to Tg, with total (Cu+Ni)-content to those of binary a-TE-TL alloys composed from the same TEs and TLs [89][90][91][92][93]. Comparing the data in Figures 5, 6 and 8 we see that a correlation between electronic structure and E is obeyed by our alloys, too.…”

“…Variation of E vs. x for (TiZrNbCu)1-x Nix and some binary amorphous alloys. Data for Zr-Cu are from [89,90], for Zr-Ni from [89,91], for Ti-Cu from [88,92,93] and Ti-Ni from [90]. Dashed lines are guide for eye.…”
