Indentation and scratch testing of coarse-grained and ultrafine-grained AA6063
Deformation behavior of coarse- and ultrafine-grained 6063 aluminum alloy ECAPed samples in indentation and scratching has been investigated. The specificity of ultrafine-grained samples was formation of pile-ups on the indentation and scratch groove edges, whose height was greatly higher than those on the coarse-grained samples. Despite the fact that the ultrafine-grained samples had their microhardness numbers higher than those of coarse-grained, the scratch grooves were deeper on the first ones.Deformation behavior of coarse- and ultrafine-grained 6063 aluminum alloy ECAPed samples in indentation and scratching has been investigated. The specificity of ultrafine-grained samples was formation of pile-ups on the indentation and scratch groove edges, whose height was greatly higher than those on the coarse-grained samples. Despite the fact that the ultrafine-grained samples had their microhardness numbers higher than those of coarse-grained, the scratch grooves were deeper on the first ones.
