  • The embrittlement of several austenitic alloys by hydrogen was studied. The high-nickel austenitic alloys were embrittled by hydrogen. This proves that the structure of an alloy is not an absolute criterion for predicting its susceptibility to hydrogen embrittlement. The theory of fractures developed by Cottrell was applied to the problem of hydrogen embrittlement. A possible explanation of the fact that it is only the transition metals which have so far been embrittled by hydrogen is also presented. The hypotheses formulated seem to be confirmed by results obtained on Ni-Cr, Ni-Fe, Ni-Cr-Fe, and Ni-Cu alloys. (auth)
  • A spectrophotometric method for determining iron in the range 0.001 to 0.125% in high-purity niobium, tantalum, molybdenum, and tungsten metals is described. After sample dissolution and reduction of iron to the bivalent state with ascorbic acid and hydroxylamine hydrochloride, the red complex formed between iron(II) and bathophenanthroline (4,7-diphenyl-1,10-phenarthroline) is extracted into n-amyl alcohol and the absorbance of the resulting extract is determined at 536 m mu . Interference from copper is eliminated with thiourea. Cobalt, cadmium, nickel, manganese, and zinc also interfere, but the amounts of each of these impurities present in the four high-purity metals described are so lowmore » that their irterference effects are negligible in the proposed method. Higitly reproducible and precise results can be obtained with careful control of the pH during reduction and extraction. (auth)« less
  • Non-heme iron centers are present in the catalytic active sites of a large number of enzymes which are involved in the binding and activation of dioxygen. A member of this class, soybean lipoxygenase (SBL), catalyzes the reaction of 1,4-unsaturated lipids with dioxygen to form a hydroperoxide product. Nitrosyl complexes of enzymes serve as reversible analogues of possible dioxygen intermediates involved in catalysis. SBL-NO and other non-heme ferrous enzyme nitrosyl complexes (formulated as (FeNO){sup 7}) exhibit an unusual S = {sup 3}/{sub 2}{sub 3}EPR signal, which is also observed in (FeNO){sup 7} model complexes. A wide range of bonding descriptions havemore » appeared for these complexes, which include [Fe{sup +}d{sup 7}(S = 3/2)-NO{sup +}(S = O)], [Fe{sup 2+}d{sup 6}(S=2)-NO{sup 0}(S=1/2)] antiferromagnetically coupled, [Fe{sup 3+}d{sup 5}(S =1/2)-NO{sup {minus}}(S = 1)] ferromagnetically coupled, and [Fe{sup 3+}d{sup 5}(S = 3/2)-NO{sup {minus}}(S=0)]. In order for the NO derivative of these enzymes to be used as a probe of electron distribution related to dioxygen reactivity, a clear understanding of the electronic structure and associated spectral features of the S = 3/2 (FeNO){sup 7} unit is required. Spectroscopic techniques and theoretical methods have been used to study SBL-NO and two S = 3/2 ground-state model complexes, FeL-(NO)(N{sub 3}){sub 2}, where L = N,N{prime},N{double_prime}-trimethyl-1,4,7-triazacyclononane and FeEDTA-NO. 20 refs., 2 figs.« less
