Effect of Re and W upon brittle fracture in Ni3Al cracks by atomic simulation

Lattice trapping limits and trapping ranges at the (0 1 0)[0 0 1], (1 0 1)[0 1 0] and (0 1 0)[1 0 1] crack orientations in Ni3Al without doping (No), with a single doping atom (Sin), and with 1 and 2 at.% doping atoms of (a) Re and (b) W.159
