ABSTRACTThe main features of the phase transformations occurring in alloys based on Ti-48 at% Al are described in order to assess their roles in microstructural development during thermomechanical processing and subsequent heat treatment. It is shown that the presence of Al-rich interdendritic γ formed during solidification plays a critical role during these processes.

Multifilamentary Superconductors

The influence of the filament microstructure on the critical current density values, Jc, of Nb-Ti multifilamentary superconducting composites has been well documented. However the development of these microstructures during composite processing is still under investigation.During manufacture, the multifilamentary composite is given several heat treatments interspersed in the wire-drawing schedule. Typically, these heat treatments are for 5 to 80 hours at temperatures between 523 and 573K. A short heat treatment of approximately 3 hours at 573K is usually given to the wire at final size. Originally this heat treatment was given to soften the copper matrix, but recent work has shown that it can markedly change both the Jc value and microstructure of the composite.
