Fabrication of Ultrafine Low Carbon Metallic Multilayer by Accumulative Roll Bonding
Abstract
The effect of grain refinements by Accumulative Roll Bonding (ARB) was investigated on low carbon steel. Optical microscopy (OM) and microhardness tests were used to check the phase changes and hardness before and after ARB. A combined technique between cold rolling and ARB was used to obtain the changes of grain size under 1 µm. Metallographic analysis reveals the change of low carbon microcrystalline one compared to the ultrafine one with increased hardness resulted from straining by ARB. The severe plastic deformation (SPD) processing of bulk metals is not straightforward due to several differences in the final microstructure at several material length scales. The plastic deformation behavior of the final material depends on many microstructural aspects, one of them being grain refinement up to amorphization caused by ARB.
