b'Figure 1. 2D schematics of the influence of multi-slip system constraint. A) The blocked and free volumes are in serial configuration, observed when the blocked volume ratio is low. B) The blocked and free volume are in parallel configuration, observed the blocked volume ratio is intermediate. C) The blocked volume is much greater than the free volume region. D) The serial configuration A deforms by forming multiple slip bands in the free volume. E) The parallel configuration B deforms by simultaneous strain bursts in the free volume and necking in the blocked volume. F) The blocked configuration F exhibits high level of work-hardening and subsequent necking2022|AFC ACCOMPLISHMENTS 41'
