Two martensitic steels (Fe-8. 5 Cr-0. 9 MoVNb and Fe-9. 0 Cr-1. 8 MoVNb), one ferritic steel (Fe-17 Cr-1. 5 MoVNb), 316 stainless steel and Ni//3Fe were irradiated with 2 MeV electrons to 1 multiplied by 10**2**3 e/m**2. The damage recovery was studied by positron annihilation and differential scanning calorimetry (DSC). Results suggest that vacancies migrate and disappear below 330 K in the martensitic phase. Vacancies in the ferritic and austenitic phases disappear around 420 K, enhancing the precipitation. Ordered Ni//3Fe has three DSC annealing stages between 400 and 600 K.

ELECTROINITIATED POLYMERIZATION OF BIS(TRICHLOROPHENOXO)-TETRAMETHYLETHYLENE DIAMINE COPPER(II) SACAK, M; Akbulut, Ural; KISAKUREK, D; TURKER, L; Toppare, Levent Kamil (Wiley, 1989-04-01) Electroninitiated polymerization of bis(trichlorophenoxo)‐N,N,N′,N′‐tetramethylethylene diamine copper(II) was achieved in acetonitrile at various peak potentials of the monomer. A constant potential approach was selected in polymerization reactions. Electrolyses were carried out under air, nitrogen, and oxygen atmospheres. Structural analyses of the polymers were done by 1H‐NMR and 13C‐NMR FT–IR spectroscopy. Molecular weights of the polymers were determined by vapor pressure (isopiestic) method.
POLYMERIZATION OF BIS(TRICHLOROPHENOXO) ETHYLENEDIAMINE COPPER (II) COMPLEX BY ELECTRO-OXIDATION Yiğit, S.; Kısakürek, D.; Türker, L; Toppare, Levent Kamil; Akbulut, Ural (Elsevier BV, 1989-02-01) Electroinitiated polymerization of bis(trichlorophenoxo) ethylenediamine copper (II) complex was carried out in dimethyl-formamide at various anodic peak potentials of the complex. The oxidation and reduction peak potentials were determined by cyclic voltammetry. These potentials were measured in tetrabutylammonium fluoroborate-dimethylformamide supporting electrolyte-solvent couple at room temperature. Polymerization reactions were carried out under air and nitrogen atmospheres using a constant potential a...

POLYMERIZATION OF BIS(2-BROMO-4,6-DICHLOROPHENOXO)BIS(PYRIDINE) COPPER (II) COMPLEX IN DMF BY ELECTROINITIATION KISAKUREK, D; SEN, S; ARAS, L; TURKER, L; Toppare, Levent Kamil (Elsevier BV, 1991-01-01) Polymerization of bis(2-bromo-4,6-dichlorophenoxo)bis(pyridine) copper (II) complex was achieved in dimethylformamide by electrooxidation. A cyclic voltammogram (CV) of the complex was obtained in dimethylformamide in advance. Constant potential yielded polymers in anode compartment only under nitrogen atmosphere and air. In the final polymer product, incorporation of neither the ligand nor the copper was observed and the post-polymerization proceeded in the absence of current. The structural analyses o...
Radiation grafting of vinyl monomers onto poly(tetrafluoroethylene) powder produced by gamma irradiation and properties of grafted poly(tetrafluoroethylene) filled low density polyethylene Akinay, E; Tincer, T (Wiley, 2001-01-31) Scrap poly(tetrafluoroethylene) (PTFE) was gamma irradiated under an ambient atmosphere in order to produce extensive chain scission and oxidative degradation. After irradiation the PTFE was ground into a fine powder (2 degrees -PTFE) and graft;ed with styrene (St), vinyl acetate (VAc), and 4-vinylpyridine (4-VP) by using the direct irradiation technique. The grafted PTFE were then blended with low density polyethylene (LDPE). The study covered the characterization of irradiated PTFE and grafted 2 degrees -...
