✦ Synopsis


A comparison of high field low temperature superconducting properties between a Nb-47W/oTi and two Nb-Ti-Ta alloys as bases of laboratory scale cables was carried out Optimization cycles needed to obtain fair superconducting properties imply intermediate thermal treatments in the range 380-400°C during deformation at cold-work of 70%. The ternary alloys exhibit excellent ductile properties as do Nb-Ti alloys. After an adequate optimization cycle the alloy Nb-38W/oTi-34W/oTa showed the best high field superconducting

properties with values of more than 600 A mm -2 at 12 Tesla and 2.15 IC Production and superconducting properties of laboratory scale Nb-Ti and Nb-Ti-Ta multifilamentary cables

## Abstract There is much discussion about the toxic effect of vanadium and aluminum contained in Ti6Al4V alloy for prosthetic implants. The goal of the present investigation was to develop new titanium alloys with sufficient mechanical properties using more biocompatible alloying elements: zirco
