According to Table 3 and Table 6 , with the increase in TM addition, the mechanical properties of Cr 0.47 Al 0.5 TM 0.03 N such as bulk modulus, shear modulus, Young’s modulus, and theoretical hardness exhibit a decreasing trend, while an increase in Cauchy pressure and Pugh’s index of ductility indicates an increased toughness and a tendency toward the mobile character of the bonds, which results in a decreased resistance against shearing.
