For the first time, an intermetallic 2Ni–Mn–Al-based alloy is prepared by self-propagating high-temperature synthesis (SHS) combined with centrifugal casting. According to X-ray diffraction data, the main phase of the SHS product is the (Ni,Mn)3Al nickel aluminide solid solution with the partial substitution of manganese for nickel. The study of the microstructure shows a low aluminum content at the boundaries of the (Ni,Mn)3Al main phase. The averaged microhardness of the synthesized alloy is 8500 ± 45 MPa and the peak hardness is 11500 MPa. The alloy exhibits soft magnetic properties. The maximum magnetization in a field of 796 kA/m (10 kOe) is Js = 1.1 (A m2)/kg (emu/g) and the coercive force is Hc = 14.3 kA/m (179.7 Oe). [ABSTRACT FROM AUTHOR] |
