Tuning the mechanical properties of functionally graded nickel and aluminium alloy at the nanoscale.

ABSTRACT: In this article, Molecular Dynamics (MD) simulation is used to investigate the tensile mechanical properties of functional graded Ni-Al (Ni₃Al) alloy with Ni coating. The grading profile, temperature, crystallographic direction, and concentration of vacancy defects have been varied and corresponding changes in the tensile properties are reported. In general, it has been revealed that functional grading may reduce the ultimate tensile strength (UTS) of this homogeneous alloy but increase Young's modulus (YM). Furthermore, MD simulations suggest that elliptically graded Ni-Al alloy has the highest UTS at low temperature while at high temperature, the largest UTS is recorded for the parabolic grading. Besides, at any temperature, the parabolically graded Ni-Al alloy shows the large
