Abstract:

The effect of alloying by 12-20 at \% Hf on the structure, the phase composition, and the thermoelastic martensitic transformations in ternary alloys of the quasi-binary NiTi-NiHf section is studied by transmission electron microscopy, scanning electron microscopy, electron diffraction, and X-ray diffraction. The electrical resistivity is measured at various temperatures to determine the critical transformation temperatures. The data on phase composition are used to plot a full diagram for the high-temperature thermoelastic B2 a dagger{''} B19' martensitic transformations, which occur in the temperature range 320-600 K when the hafnium content increases from 12 to 20 at \%. The lattice parameters of the B2 and B19' phases are measured, and the microstructure of the B19' martensite is analyzed.
