## Description

- description: 'The deformation behavior of B1-type stoichiometric TiC and off-stoichiometric
    (Ti0.96, Mo0.04)C0.67 was investigated by micropillar compression test utilizing
    an in situ scanning electron microscope. The yield stress of (Ti0.96, Mo0.04)C0.67
    was found to be sufficiently lower than that of the stoichiometric TiC. In addition,
    the {001}<11¯0>, {110}<11¯0>, and {111}<11¯0> slip systems were identified to
    be active during the plastic deformation of (Ti0.96, Mo0.04)C0.67. The critical
    resolved shear stresses of these slip systems decreased in the following order:
    {110}<11¯0> (5.6 GPa), {001}<11¯0> (5.0 GPa), and {111}<11¯0> (4.4 GPa). In contrast
    to the stoichiometric TiC, which underwent complete fracture at a relatively early
    stage of deformation, (Ti0.96, Mo0.04)C0.67 deformed under >10 % plastic strain
    without fracturing, with crack preferentially initiating along the {001} plane.
    The findings demonstrate that the off-stoichiometry of (Ti0.96, Mo0.04)C0.67 improves
    plastic deformability and has a suppressive effect on crack propagation. The enhanced
    deformability may be attributed to the significantly reduced shear modulus caused
    by off-stoichiometry. © 2025 The Authors'
