    • THE BIREFRINGENT PROPERTY OF AN OPTICAL RESIN FOR THE STUDY OF A STRESS FIELD DEVELOPED IN A THREE POINT LOADING BEAM 

      TOUAHIR, K; BILEK, A; LARBI, S; DJEBALI, S (Université des Frères Mentouri Constantine, 2013-12-16)
      The birefringent property, known also as the double-refraction phenomenon, is used in a polariscope to study a stress field developed in a three point loading beam. The model used for this analysis was made of an epoxy ...
    • THE EFFECT OF EG POLYMER ON THE STRUCTURAL AND OPTICAL PROPERTIES THIN FILMS OF IN2O3 PREPARED BY SOL-GEL PROCESS 

      DJEHA, L; BOUDJADAR, S; BAOUNI, L (Université des Frères Mentouri Constantine, 2013-12-16)
      Nanocrystalline In2O3 thin films have been deposited on glass substrates by Sol- Gel spin coating technique. DRX, AFM, photoluminescence and UV-vis spectra characterization was used for study the effect of Ethylene glycol ...
    • THE EFFECT OF THE SI CONTENT ON THE MICRO-STRUCTURE AND MECHANICAL PROPERTIES OF Ti-Si-N 

      DERGHAM, D; KHEN, A; ZAIRI, A; SAOULA, N; CHEKOUR, L (Université des Frères Mentouri Constantine, 2013-12-16)
      This work deals with the deposition and characterization of (Ti-Si-N). This films with different content of Si have been deposited on Si (100) substrate by radio frequency magnetron sputtering. The influence of Si content ...
    • THE POTENTIAL DEPENDENCE OF Co–Mo ALLOY THIN FILMS 

      MESSAOUDI, Y; AZIZI, A; FENINECHE, N; SCHMERBER, G (Université des Frères Mentouri Constantine, 2013-12-16)
      Co-Mo alloys thin films were electrodeposited on ruthenium substrate from sulfate solution without additives at pH=4. The conditions of electrodeposition of Co-Mo alloys were determined using the electrochemical methods ...
    • THERMAL RESIDUAL STRESS THROUGH HDPE PIPEWALL COMBINING ON LAYER REMOVAL AND RING SLITTING METHODS 

      SERSAB, D; ABERKANE, M (Université des Frères Mentouri Constantine, 2013-12-16)
      Residual stresses, in high density polyethylene (HDPE) pipes, result from a non homogenous cooling rate that occurs between the inner and outer surfaces causing heterogeneity of material’s molecular structure inducing ...
    • THIN FILMS GROWTH FROM ALUMINA TARGET IRRADIATED BY A KrF LASER 

      YAHIAOUI, K; ABDELLI-MESSACI, S; MESSAOUD ABERKANE, S; KHEREDDINE, Y; KELLOU, H (Université des Frères Mentouri Constantine, 2013-12-16)
      We report on alumina thin films growth from α-Al2O3 target by pulsed laser deposition. The alumina plasma was induced by a KrF laser beam at a wavelength of 248 nm and pulse duration of 25 ns. The laser fluence was set ...
    • THIN FILMS OF ZnO DOPED Sb SYNTHESIS BY SPRAY PYROLYSIS 

      MEKHNACHE, M; DRICI, A; BENZAROUK, H; AMARA, A; GUERIOUNE, M (Université des Frères Mentouri Constantine, 2013-12-16)
      Sb doped ZnO thin films were prepared on glass substrates using the spray pyrolysis. Structural and optical properties were investigated. A ZnCl2 (0.2M) dissolved in water. Antimony chloride (SbCl3) was used as dopant ...
