Abstract
Slip blockage during slip band intersections impacts mechanical properties of crystalline materials. Molecular dynamics simulations of eight band intersections in Fe70Ni10Cr20 alloys revealed that secondary bands always transmit into ε bands more easily than into twin bands. While this is surprising because the ε-phase has a different crystal structure from the matrix, our finding that twins do not possess easy crystallographic pathways for transmission explains this phenomenon. We also found that the band intersection regions preferentially nucleate voids. These findings provide understanding of the deformation and damage behavior of FCC metals. For example, since hydrogen promotes ε-bands, our findings can help understand hydrogen compatibility.
