Abstract: The effect of long-term exposure of titanium nickelide in a dc nonuniform magnetic field on the phase transformation in it is studied. The magnetic field is shown to change the phase composition of an equiatomic Ti–Ni alloy and to substantially change its magnetic properties. This effect can be related to the appearance of magnetic Ti$_2$Ni and Ni$_3$Ti phases, which result from local deformation of the crystal lattice of TiNi.
