摘要：

A high-pressure study of the crystal structure and superconductivity of Ti-Zr alloys demonstrates an increase in the omega-beta -transition pressure from about 30 to 43-57 GPa when the titanium content in the alloys increases from 0 to 50 at. %. The isobaric values of the BCC beta -phase superconducting temperature (at 46 GPa) increase from 5.7 to more than 15 K between 0 and 50 at. % Ti, the latter value being the absolute maximum for BCC d-metal alloys. These data correlate with the earlier assumption of an s-d electron transfer in Zr under pressure. (C) 2001 MAIK "Nauka/Interperiodica".
