    Addition of copper in high-carbon bainitic steel has resulted in attractive elongation. Heterogeneous copper precipitation in the course of bainitic transformation, at low homologous temperature, has resulted into attractive strength–ductility combination despite the limited dislocation controlled plasticity of nanoscale bainite. Early yielding of bainite facilitates strain partitioning between the blocky austenite and bainitic sheaves, leading to the continuous work hardening. In contrast to the tensile fracture strain, the compressive fracture strain has been found to be less dependent on the austenite volume fraction. The nanoindentation results indicated limited work hardening of the bainite sheaves.
