- Abstract
- This paper reports on structure and phase formation of a Ni–Al–Co based alloy prepared by self-propagating high-temperature synthesis. The maximum combustion temperature was 1020°C in argon and 913°C in vacuum. The phase composition of the synthesized alloy includes a Ni0.7Co0.3 solid solution with a cubic (Pm m) crystal lattice. Its microstructural constituents based on γ- and β-phases are 10–20 μm in size, and γ + β interlayers located on the interface between the γ- and β-phases are up to 1–2 μm in thickness. The alloy offers high plasticity, and its compressive strength is 451 MPa. Its low remanence, low coercive force, and high saturation magnetization indicate that the alloy is a soft magnetic material. It has a coercive force Hc = 146 Oe, remanent magnetization σr = 0.35 emu/g, and saturation magnetization σs = 36.76 emu/g.
