Characterization of double aluminium alloy specimens after equal channel angular pressing ecap part two total

Jan 01, 2018The Equal Channel Angular Processing or pressing, i.e. the ECAP, allows to modify the properties of materials at the microstructure level. It consists in the induction of a high amount of shear deformation in the material that leads in general to a grain size refinement, a precipitate dispersion and a redistribution of dislocations depending on experiment conditions.Cited by 62Publish Year 2010Author P.W.J.

The need and essence of the multi-pass process is explained in detail.Successive Mean Quantization Transform Optimization ToptalComplexityImprovementParallelismComplexity CompariThe algorithm requires that for each level of quantization (L), N elements must be inspected in a first pass to find the mean for each vector, and then in a second pass, each of those N elements must be compared to the corresponding mean in order to split each vector in turn. Finally, N elements must be substituted by their codes. Therefore the algorithms complexity is O((L*2*N) + N) = O((2*L + 1)*N), which is O(L*N).
