Texture Formation in a Polycrystalline Fe–Ni–Co–Al–Ti–B Shape Memory Alloy

A study of the properties and development in technology for obtaining multi-component systems of particle reinforced aluminum and titanium alloys

“…Previous studies of the Al-Ti-B system with the addition of Fe, Ni, CO have shown memory form in the study by the method of reverse scattering of electrons (Kocks et al, 2000;Lee et al, 2020). The increasing scope of multicomponent Ti-Fe-B systems will greatly expand the possibility of the application of the developed material.…”

Effect of Al Content on Abnormal Grain Growth and Superelasticity in Fe–Mn–Al–Cr–Ni Shape Memory Alloys with Near-Zero Temperature-Dependence of Transformation Stress

“…In the case of Fe-Ni-Co-Al-based polycrystalline alloys [4][5][6], low-energy grain boundaries, obtained by heavy cold-rolling and subsequent heat treatment, are necessary to suppress grain boundary precipitation to achieve good ductility and superelasticity. Thus, the applications of these alloys are restricted to thin sheet samples [13][14][15][16]. Although the single crystals of these alloys show superior superelasticity [17][18][19], the fabrication cost through traditional method is expensive.…”

“…

The solvus temperature of face-centered cubic (FCC) phase in 14,and 15) shape memory alloys with different Al contents, and their abnormal grain growth and superelasticity at various temperatures were evaluated. With increasing Al content, the solvus temperature of the FCC phase decreased and the FCC precipitates became finer.
