Shape memory behavior in ti–zr alloys
Webb5 feb. 2024 · Among modern metal–ceramic composites, materials based on a metal matrix with shape memory have an important place. Such materials with a composition based on a titanium nickelide (TiNi) intermetallic compound and the reinforcing particle titanium diboride (TiB 2) are the investigated in this article [ 28, 29, 30 ]. Webb19 dec. 2024 · The curves show two desorption peaks at around 200 and 650 °C in all samples. The first broad peak located at ~200–300 °C is associated with the desorption process of the chemisorbed oxygen on the material surface. The second oxygen desorption peak may be ascribed to the reduction of Fe 4+ to Fe 3+ at 300–650 °C [ 23 ].
