Martensite transformation from ultrafine-grained (UFG) austenite fabricated by the accumulative roll-bonding (ARB) process in an Fe-28.5 at.% Ni alloy was studied. The sheet ARB processed by five cycles (equivalent strain: ε = 4.0) showed the ultrafine lamellar austenite grains with the mean lamella
