摘要：
The paper presents the experimental results on an aluminum alloy processed by equal channel angular extrusion in order to refine the grains. Microstructure was analyzed by optical microscopy. The average grain size has been refined from 100 mu m before ECAE to 5 mu m after four passes. The grains are subsequently evolved with further pressings into a reasonably equiaxed and homogeneous microstructure. Microhardness of fine grained aluminum alloy has been investigated and it shown that increased substantially by the first pass.
