'''Accumulative roll bonding''' (ARB) is a severe plastic deformation (SPD) process. It is a method of rolling a stack of metal sheets, which are repeatedly rolled to a severe reduction ratio, sectioned into two halves, piled again and rolled. It has been often proposed as a method for the production of metal materials with ultrafine grain microstructure. ARB is a modification of repeated forging and folding method which has been in use since the end of Bronze Age or the beginning of Iron for sword making.<ref>{{cite journal|last=Edalati|first=K.|author2=Bachmaier, A. |author3=Beloshenko, V.A. |author4=Beygelzimer, Y. |author5=Blank, V.D. |author6=Botta, W.J. |author7=Bryła, K. |author8=Čížek, J. |author9=Divinski, S. |author10=Enikeev, N.A. |author11=Estrin, Y. |author12=Faraji, G. |author13=Figueiredo, R.B. |author14=Fuji, M. |author15=Furuta, T. |author16=Grosdidier, T. |author17=Gubicza, J. |author18=Hohenwarter, A. |author19= Horita, Z. |author20=Huot, J. |author21=Ikoma, Y. |author22=Janeček, M. |author23=Kawasaki, M. |author24=Krǎl, P. |author25=Kuramoto, S. |author26=Langdon, T.G. |author27=Leiva, D.R. |author28=Levitas, V.I. |author29=Mazilkin, A. |author30=Mito, M. |author31=Miyamoto, H. |author32=Nishizaki, T. |author33=Pippan, R. |author34=Popov, V.V. |author35=Popova, E.N. |author36=Purcek, G. |author37=Renk, O. |author38=Révész, A. |author39=Sauvage, X. |author40=Sklenicka, V. |author41=Skrotzki, W. |author42=Straumal, B.B. |author43=Suwas, S. |author44-link=Laszlo S.
