Abstract:

A magnetorheological material containing iron alloy particles demonstrates magnetorheological strength dependent upon the elements of the alloy and relative concentration of the alloy elements. Selected iron/cobalt alloys demonstrate improved yield strength over traditional carbonyl iron based MR materials when the iron-cobalt alloy has an iron-cobalt ratio ranging from about 30:70 to 95:5. The iron-nickel alloys which have an iron-nickel ratio ranging from about 90:10 to 99:1 maintains superior strength over iron-nickel alloys outside that range.

Abstract:

This article presents the results of an X-ray spectral microanalysis of cobalt-chromium alloys based on particles of the of the tungsten nickel iron alloy dispersed by electric erosion, obtained in alcohol. It has been experimentally proved that a part of oxygen is present in the cobalt-chromium alloy of particles of the cobalt-chromium-molybdenum alloy dispersed by electric erosion. All other elements are distributed relatively evenly over the volume of particles. It is shown that Co, Cr and Mo are the main elements of the (CoCrMo) alloy dispersed by electric erosion.

Abstract:

Nine cast alloys reinforced by very high fractions of carbides, Ni-30Cr-xC, Co-30Cr-xC and Fe-30Cr-xC with x varying from 1.2 to 2.0, were tested in oxidation at high temperature between 1,000 and 1,200°C in air for 50 hours. After oxidation, their surfaces and sub-surfaces were characterized. Even for very high carbon contents, the chromia-forming behaviour of the nickel alloys is kept. The oxidation modes of the cobalt alloys and iron alloys are not changed compared to low carbon alloys of these families. The differences of diffusion easiness of chromium in matrix, between nickel alloys, cobalt alloys and iron alloys are the same as for alloys with lower carbon contents, as suggested by the lower chromium gradients in the nickel alloys compared to the two other alloy types. Sub-surface microstructure transformations due to oxidation were observed in some cases (coarsening of carbides due to an inwards diffusion of carbon, change of the sharing between BCC-FCC of iron matrix due to outwards diffusion of chromium). Catastrophic oxidation never occurred for these alloys during the 50 hours of exposition to air at high temperature.

Abstract:

Cobalt and its alloy have been identified as potential candidates for replacing hexavalent Chromium plating in corrosion resistant coating in acidic environment. In this study, the effect of alloys addition towards elemental composition, crystallographic structure characterization, surface morphology, hardness and potentiodynamic polarization of the cobalt alloys coatings is reported. Addition of Nickel (Ni) and Iron (Fe) to the Cobalt (Co) coatings are deposited on stainless steel substrate by electrodeposition method. The deposition is performed at acidic environment of pH 3. The granule sizes of cobalt alloys prepared by electrodepositionmethod are in the range of 34.95 nm72.08 nm. The microhardness of CoNiFe is the highest (267.8 HV) compared to Co and CoFe. CoNiFeperforms the smallest corrosion rate with 1.322 mmpy. It is found thatthe addition of Ni and Fe into pure cobaltimproves the hardness and corrosion behavior.

Abstract:

The United States Air Force is in the process of developing magnetic bearings as well as an aircraft Integrated Power Unit and an Internal Starter/Generator for main propulsion engines. These developments are the driving force behind a new emphasis on high temperature, high strength magnetic materials for power applications. Analytical work, utilizing elasticity theory, in conjunction with design requirements, indicates a need for magnetic materials to have strengths in excess of 80 ksi up to about 1000 degrees F. It is this combination of desired material characteristics that is the motivation for this effort to measure, model, and predict the creep behavior of such advanced magnetic materials. HipercoÂ® Alloy 50HS, manufactured by Carpenter Technology Corporation, is one of the leading candidates for application and is studied in this effort by subjecting mechanical test specimens to a battery of tensile and creep tests. The tensile tests provide stress versus strain behaviors that clearly indicate: a yield point, a heterogeneous deformation described as LuÌ ders elongation, the Portevin-LeChatelier effect at elevated temperatures, and, most often, a section of homogeneous deformation that concluded with necking and fracture. Creep testing indicated two distinct types of behavior. The first was a traditional response with primary, secondary and tertiary stages, while the second type could be characterized by an abrupt increase in strain rate that acted as a transition from one steady state behavior to another. This second linear region was then followed by the tertiary stage. The relationship between the tensile response and the creep responses is discussed. Analyses of the mechanical behavior includes double linear regression of empirically modeled data, scanning electron microscopy for microstructural investigations, isochronous stress-strain relations, and constant strain rate testing to relate the tensile and creep test parameters. Also, elastic and creep deformation analyses are done, which incorporate material property data and material constants determined along with stress and displacement profiles for a specific Air Force design configuration.<br>Ph.

Abstract:

A study of the electrochemical formation of functional coatings by binary and ternary alloys M1M2, M1M3, M1M2M3 (where M1 is 3d6-8 metal of the iron subgroup: Fe, Co, Ni, and M2 is Mo, W; M3 is Re), from complex aqueous solutions and ionic melts. Such alloys are called "superalloys" due to a wide range of valuable physicochemical (corrosive, electrocatalytic) and functional properties and are designed to operate in extreme temperature and power modes with simultaneous exposure to an aggressive environment. The presence of rhenium in the alloy also simultaneously increases its strength and ductility (the so-called "rhenium effect"). A fundamentally new electrolyte (highly concentrated ammonia-acetate) has been developed for the formation of molybdenum alloys (NiMo, CoMo, FeMo) with a maximum content of a refractory component (about 85 at.%), such as those that exhibit a high electrocatalytic effect in the hydrogen evolution reaction (HER). The deposition of binary CoRe and ternary CoWRe alloys from a citrate electrolyte was carried out. The influence of the composition of solutions and electrolysis parameters on the chemical and phase composition, structure and properties of coatings has been established. The parameters of pulse electrolysis for obtaining multilayer CoMo and CoW coatings from carbamide melts containing cobalt and molybdenum / tungsten oxides have been determined.

Abstract:

AbstractThis review highlights select methods from the synthetic organic metal hydride hydrogen-atom transfer (MHAT) literature. Following MHAT to an alkene, carbon-centered radicals are captured to forge bonds between carbon and hydrogen, oxygen, nitrogen, the metal center itself, or other atoms. Isomerization is also known, proceeding via abstraction of an adjacent hydrogen atom. Oxidation or reduction of the MHAT-generated carbon-centered radical allows for coupling with two-electron nucleophiles or electrophiles in radical–polar crossover methods. Cross-coupling-type transformations have also emerged, enabled by secondary metal capture of the radical intermediate. The field is evolving from classical catalytic turnover (oxidation/hydride reduction) to other modes of reductive turnover, primarily represented by photocatalytic and electrochemical methods. Opportunities for novel modes of turnover, enantioselective synthesis, and mechanism interrogation promise to drive the MHAT field forward.

Abstract:

A high-strength, low-expansion alloy can greatly increase the efficiency of gas turbines by permitting decreased clearances between rotating and stationary parts. This paper describes development work on a series of nickel-iron-cobalt alloys having the desired combination of high strength and low thermal expansion. The first attempts to develop alloys of this type resulted in materials that required extensive thermomechanical processing and were susceptible to the phenomenon of stress-accelerated grain-boundary oxygen embrittlement (SAGBO). Further development resulted in INCOLOY alloy 909, the first low-expansion superalloy combining good resistance to SAGBO with high mechanical properties achieved without restrictive thermomechanical processing. Those substantial improvements were brought about by the addition of 0.3% to 0.6% silicon to a low-aluminum, 38% nickel, 13% cobalt, 1.5% titanium, 4.7% niobium (columbium), balance iron composition.

Abstract:

Abstract Wall Colmonoy Ltd has developed a new generation of Iron-based powder alloys providing superior resistance to dry wear and excellent corrosion resistance. These alloys are economically interesting because they contain none or very low levels of expensive and market sensitive metals such as nickel and cobalt. These powders are marketed under the trade name Colferoloy. This paper details the properties and advantages of Colferoloy when compared to current “traditional” surface treatment methods and consumables. Metallurgical examination of the Colferoloy deposits showed that the alloy formed sub-micron structures which afford excellent dry-wear resistance, whilst the high chromium content provides good resistance to corrosion. Colferoloy alloys were applied using HVOF techniques to engineering components producing dense coatings with a hardness in the range of 950-1000 Vickers. The cost benefits of using an Iron-based alloy with low density hard phases were studied and comparisons with traditional materials were performed. This study showed that Colferoloy is a viable alternative to current hardfacing alloys and treatments.

Abstract:

Abstract Cermets like WC/Co or Cr3C2/Ni20Cr are well-established materials for thermally sprayed wear protection coatings. However, their high price and the adverse health effects of nickel and cobalt cause the motivation for the development of novel materials with excellent wear resistance. Within the AiF/DFG research cluster “Thermal Spraying”, a multi-institutional cooperation of various German research centres, the focus is put on particle-reinforced iron-based composite alloys. High-alloyed steels serve as matrix materials into which hard CrB2 particles are incorporated by means of high-energy ball milling (HEM). By adjusting appropriate milling parameters, the microstructure of the powder and its level of amorphisation can be influenced effectively. The high-velocity oxygen fuel process (HVOF) allows a transfer of the desired nanocrystalline structure from the particles to the coatings. The deposited coatings exhibit low porosity and high microhardness values of more than 1000 HV0.3. The wear resistance of the coatings was determined by means of Miller test (ASTM G75-01) and compared with conventional wear protection materials and coatings produced with agglomerated and sintered powders. The obtained outstanding results qualify particle-reinforced iron-based materials as a promising alternative for a wide range of applications.

Abstract:

Abstract High temperature corrosion is a serious problem on tlie heat exchanger tubes of recuperators because they encounter an corrosive environment at maximum temperature around 900°C. These tubes were found to be corroded via oxidation, sulfidation and molten salt corrosion. Particularly molten salt corrosion could be the most severe corrosion mechanism. As a protective coating for recuperators, nickel and cobalt based self-fluxing alloys, iron based amorphous alloy and chromium carbide cermet coatings were considered. These coatings were prepared by an arc spray and or/not fusing or a HVOF spray. Their molten salt corrosion resistance was tested, and the high temperature corrosion resistance in a SO2 containing atmosphere was examined. Also microstructures of the coatings were studied after corrosion tests.

Abstract:

Coatings such as NiCrA1Y, CoCrA1Y and FeCrA1Y are deposited by plasma spraying under partial pressure on commercial f.c.c. alloys of nickel, cobalt, and iron. The interdiffusion between coating and substrate is limited in the cases of NiCrA1Y/Ni base and CoCrA1Y/Co base. On the other hand, rapid diffusion of the aluminium into the substrate occurs in the system FeCrA1Y/Fe base. When mixed systems MCrA1Y/M’ base are studied, an interdiffusion is usually observed between the elements M and M’ except in the case of the systems NiCrA1Y/Co base and FeCrA1Y/Co base where carbide diffusion barriers are formed.

Abstract:

This report presents a review of quasi-static and dynamic properties of various iron, titanium, nickel, cobalt, and aluminum metals. The physical and mechanical properties of these materials are crucial for developing composite armoring systems vital for protecting critical bridges from terrorist attacks. When the wide range of properties these materials encompass is considered, it is possible to exploit the optimal properties of metal alloys though proper placement within the armoring system, governed by desired protective mechanism and environmental exposure conditions.
