Fig.6 Distributions of the crack susceptibility coefficient with compositions for Co-Ti-Al (a-c), Ni-Si-Hf (d-f) ternary alloys at cooling rates of 10 K/s (a, d), 100 K/s (b, e), and 1000 K/s (c, f)[85] (LN (CSC) indicates the logarithm of the thermal crack sensitivity coefficient, the higher the value, the stronger the tendency to produce thermal cracks)
