N2 - In this paper, NiAl-33Cr-4.5Ta (at. pct) near-eutectic alloy consisting of NiAl, α-Cr and Laves is successfully designed by JMatPro software and verified by experiments. TEM result reveals that it exists an orientation relationship between each two phases. Directionally solidified (DS) alloy has a well-aligned microstructure and possesses a fracture toughness (9.8 MPa·m1/2). Moreover, the DS alloy has a tensile ductility (1.4 pct) at room temperature. Fracture behavior is analyzed by the crack propagation and fracture surface. Graphical Abstract: [Figure not available: see fulltext.]
