Manufacturing and mechanical behavior of titanium-steel composite by accumulative roll bonding

Abstract

Metal matrix composites have attracted interest for use in several engineering applications and this study focuses on the fabrication titanium and interstitial free steel composite and its mechanical performance. Accumulative roll bonding (ARB) was employed as a severe plastic deformation method to fabricate the multi-layered composite up to three cycles where an aluminum alloy is utilized as an interlayer material. Improvement in hardness and strength levels was achieved with an increased number of ARB cycles. Although, the composite obtained after three cycles indicated a brittle behavior, a decent tensile response of around 650 MPa and 10% ductility was demonstrated after two ARB cycles.
