Ultrafine-grained Cu/Al/Ag composites were processed by an accumulative roll bonding (ARB) technique from pure copper and aluminum sheets a silver powder. The Al content was fixed to 11 wt.% while the concentration 1, 2, or 3 in wt.%. ARB-processed samples heat treated at different temperatures between 750 1050 °C for 60 min then quenched room temperature (RT) producing Cu–Al–Ag alloys. effect ...

In this research accumulative roll bonding process as sever plastic deformation process was applied up to 8 cycles to produce the ultrafine grain copper. Microstructure of cycle 1, cycle 4 and cycle 8 investigated by TEM images. By analyzing TEM images the grain size measured below 100 nm in cycle 8 and it was with an average grain size of 200 nm. Corrosion resistance of rolled copper stri...

In the present study, the capability of accumulative roll bonding (ARB) and subsequent heat-treatment to fabricate solid solution from a multilayered Cu/Zn/Al was investigated. Two post-heat treatment (one-step and two-step) routes were proposed. In the first, the ARB processed material was heated to 800 C for 5:30 hours and allowed to cool slowly in a furnace (one-step route). In the second (t...

techniques of severe plastic deformation have been successfully used for the production of novel metallic microstructures. among different types of these techniques, accumulative roll bonding (arb) has been extensively used to produce multi-layered composites. in the present study, a new manufacturing process for cu/ni- 1vol% fe3o4 composites was developed by using copper and nickel sheets toge...

Accumulative roll bonding is an advanced manufacturing process, which capable of simultaneously refining the grain size into nanometer regime and different metallic sheet materials. Herein, homogenous aluminum/aluminum as well heterogeneous aluminum/steel laminated metal composite (LMCs) are fabricated. The residual stresses experimentally determined by X-ray diffraction hole-drilling method. G...
