Abstract
The microstructure of a cold-rolled tape made of Nb–50 wt % Ti superconducting alloy before and after heat treatment has been investigated by transmission electron microscopy, scanning transmission electron microscopy, and microanalysis (including the mode of in situ annealing in the electron microscope column). The influence of heat treatment on the concentration and lateral sizes of α-Ti particles has been calculated. The Ti phase inclusions with fcc lattice are found in the α-Ti particles after in situ annealing.
