Phase-field modeling of $\gamma /{\gamma }^{\prime \prime }$ microstructure formation in Ni-based superalloys with high ${\gamma }^{\prime \prime }$ volume fraction

Felix Schleifer, Markus Holzinger, Yueh-Yu Lin +2

The excellent mechanical properties of the Ni-based superalloy IN718 mainly result from coherent ${\gamma }^{\prime \prime }$ precipitates. Due to a strongly anisotropic lattice misfit between the matrix…
