Multi-scale analysis by EBSD, X-ray diffraction and neutron diffraction of microstructure and texture of Al-Mg-Si aluminum alloy wires drawn and annealed; 27th Int. METAL 2018 [Internet]. 2018.
Publisher's VersionAbstract
The ENICAB company in Biskra uses the cold drawing process on several types of wires rod of different materials and grades. Our study was carried out on an Al-Mg-Si (AA6101) aluminum alloy wire rod, the most used by the ENICAB company in the manufacture of electrical energy transmission cables. The purpose of this work is to understand the evolution of the deformation texture and the stored energy in the grains during cold drawing of wire, as well as the combined influence of deformation and annealing at 400 °C during different holding time on recrystallization kinetics and evolution of local and global crystallographic texture. Characterization methods used in this work is: Optical Microscopy (OM), Scanning Electron Microscopy (SEM), Back Scatter Electron Diffraction (EBSD), X-ray diffraction, Neutron diffraction, Vickers microhardness and Chemical analysis by EDS.

A New Class of Fredholm Integral Equations of the Second Kind with Non Symmetric Kernel: Solving by Wavelets Method. Boletim da Sociedade Paranaense de Matem´aticaBoletim da Sociedade Paranaense de Matem´atica. 2018.
AbstractIn this paper, we introduce an efficient modification of the wavelets method to solve a new class of Fredholm integral equations of the second kind with non symmetric kernel. This method based on orthonormal wavelet basis, as a consequence three systems are obtained, a Toeplitz system and two systems with condition number close to 1. Since the preconditioned conjugate gradient normal equation residual (CGNR) and preconditioned conjugate gradient normal equation error (CGNE) methods are applicable, we can solve the systems in O(2n log(n)) operations, by using the fast wavelet transform and the fast Fourier transform.
