Bifurcation in deformation behavior of Cu and Ta by accumulative roll-bonding at high temperature Academic Article uri icon


  • 2017 Cu and Ta are co-deformed at 673K by the accumulative roll-bonding technique up to 8 passes. At an equivalent von Mises strain (vm) of ~2 the deformation is bifurcated into shear accommodated by the soft Cu, and plane-strain by the hard-but-ductile Ta. This is attributed to transitions occurring collectively at vm ~2 in crystallographic texture, partitioning of recovery and recrystallization, and the nature of interfaces as elucidated by orientation relations, Hall-Petch behavior and manifestation of instabilities at higher strain.
