Ultra-fine Grained Bulk Steel Produced by Accumulative Roll-bonding (arb) Process
Much attention has been directed recently to ultra-grain refining of metallic materials, where the grain size is reduced to less than 1 mm. It is expected that submicrometer grained structure would result in high strength and toughness at ambient temperature [1] as well as high strain rate or low temperature superplasticity at elevated temperatures [2,3]. It has been reported recently that ultr...
متن کاملINVESTIGATING THE CORROSION BEHAVIOR OF NANO STRUCTURED COPPER STRIP PRODUCED BY ACCUMULATIVE ROLL BONDING (ARB) PROCESS IN ACIDIC CHLORIDE ENVIRONMENT
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...
متن کاملINVESTIGATION OF TRIBOLOGICAL CHARACTERISTICS OF AL/NANO SiO2NANOCOMPOSITES PRODUCED BY ACCUMULATIVE ROLL BONDING (ARB) PROCESS
Accumulative roll-bonding process (ARB) is an important severe plastic deformation technique for production of the ultrafine grained, nanostructured and nanocomposite materials in the form of plates and sheets. In the present work, this process used for manufacturing Al/SiO 2 nanocomposites by using Aluminum 1050 alloy sheets and nano sized SiO 2 particles, at ambient temperature. After 8 cycle...
