Plastic anisotropy of ultrafine grained Al alloy AA6016 produced by accumulative roll bonding

摘要

In order to quantify the plastic anisotropy of the ultrafine grained aluminium alloy AA6016 produced by accumulative roll-bonding (ARB) the Lankford parameter is measured bytensile testing as a function of the number of ARB cycles. The experimental results are comparedwith those from texture-based Taylor simulations. Increasing differences between experiment andtheory at higher number of ARB cycles may be attributed to highly oriented microstructuralfeatures.
