Incremental ECAP as a method to produce ultrafine grained aluminium plates
Abstract
In this work, we propose a new approach to produce ultrafine grained plates using a modified ECAP method, namely incremental ECAP. Unlike conventional ECAP, incremental ECAP works in small steps in which deformation and feeding are divided between two different tools acting asynchronously. Incremental processing reduces forces and allows processing relatively large billets. The major advantage of this technique is that the specimens are in the form of plates with rectangular shape, which makes them suitable for further processing, e.g. via deep drawing. We report here a study on microstructure development, mechanical properties and their anisotropy in aluminium plates processed by incremental ECAP. Eight passes applied (accumulated strain of 9.2) with rotation about Z axis brought about the reduction of grain size down to 600 nm with 80% fraction of high angle grain boundaries and very homogenous equiaxial microstructure. This resulted in a significant increase in mechanical strength with an ultimate tensile strength reaching 200 MPa and more importantly very low anisotropy with respect to rolling direction
