The effect of slip transfer on heterogeneous deformation of polycrystals has been a topic of recurring interest, as this process can either lead to the nucleation of damage, or prevent nucleation of damage. This paper examines recent experimental characterization of slip transfer in tantalum, TiAl, and Ti alloys. The methods used to analyze and assess evidence for the occurrence of slip transfer are discussed. Comparisons between a characterized and simulated patch of microstructure are used to illustrate synergy that leads to new insights that cannot arise with either approach alone.
