A novel bi-layered steel composite consisting of a martensitic steel and a high manganese twinning-induced plasticity (TWIP) steel has been fabricated by roll bonding at high temperature. Microstructural and mechanical characterizations highlight that the presented bi-layered steel composite exhibits simultaneously a high yield stress and high uniform elongation, as both the advantages of TWIP steel and martensitic steel are inherited.
