ICAPMA_2017 Measurements of recrystallization kinetics by isochronal DSC in industrial drawn copper wires Lahcene Fellah a, * and Zakaria Boumerzoug b a Faculty of Hydrocarbons and renewable Energies and Earth and Universe Sciences,University of Kasdi Merbah, P.o.Box 511 route de Ghardaïa, Ouargla 30000, Algeria b Laboratory of Semiconductors and Metallic Materials, University of Biskra, P.o.Box 145 RP, Biskra 07000, Algeria Abstract The aim of this research is to study the kinetics of recrystallization and to determine various microstructural parameters after isochronal annealing of a cold-deformed copper wire by drawing. Appropriate measurement techniques were used such as differential scanning calorimetry(DSC) and X-ray diffraction (XRD). The refinement of XRD patterns was carried out by using the PM2k software. The energy stored by the dislocations and the activation energy were estimated by DSC under isochronal conditions using a different methods such as Kissinger, Ozawa, Boswell and Starink. In addition, the recrystallized fraction was determined as a function of temperature and some kinetic parameters. We noted that the increase of heating rates pushes up the recrystallization reaction. We observed a combined effect of the heating rate and the deformation level on the recrystallization parameters. When the heating rate and the deformation level are high then the recrystallization temperature, the stored energy by the dislocations, and the dislocation density will be high. © 2018 Elsevier Ltd.

Introduction When a metallic sample is cold drawn, most of the mechanical energy provided is transformed into a heat and the remainder is stored as a defects, mainly, dislocations [1]. When the cold drawn sample is annealed, the stored energy resulting from the deformation tends to dissipate generating changes in the amount and distribution of defects, * Corresponding author.
