Abstract:

<p class="TTPAbstract">The problems of production of copper-nicckel alloys ingots by semicontinuous casting method are analysed. The requirement of grain size refinement in cast alloys macrostructure is shown. It is necessary to reduce the probability of hot cracks formation and increase the fabricability of cast bars during plastic working. The reasonability of fine fraction of Ni-Mg-Ce master alloy application for inoculation of copper-nickel alloys is established. The results of laboratory experiments on the study of master alloy quantity influence the structure and hardness of Cu-5Ni

Abstract The paper explores the possibility of using a number of nickel alloys in multilayer coatings to decrease nickel consumption and preserve the functional effect of the coating. The following is proved by the graphical calculation technique using experimental data on the galvanic properties of the multilayer coating parts. Nickel-iron, nickel-phosphorus and nickel-tin alloy can be applied as a lower coating layer rather than semi-shiny, shiny or composite nickel. It is advisable to use a nickel-iron alloy as the middle (second) layer, and the concentration of iron depends on the composit

Abstract:

Copper–nickel alloys are widely applied in marine engineering due to their excellent mechanical properties and corrosion resistance. This study investigates the effect of chromium (Cr) on the erosion–corrosion behavior of copper–nickel alloys through erosion–corrosion experiments. The results indicate that the alloy containing Cr exhibits enhanced erosion–corrosion resistance. The addition of Cr reduces the corrosion rate of the copper–nickel alloy from 0.206 mm/a to 0.060 mm/a. This improvement in corrosion resistance is mainly attributed to the formation of (Ni/Fe)3Cr phases, which enhance t

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:

The aim of this work is to obtain predictive regression models, with which it is possible to adequately calculate the mechanical properties of heat-resistant nickel alloys, without prior experiments. Industrial alloys of directional crystallization of domestic and foreign production were selected for research. The values were processed by the method of least squares to obtain correlations with the receipt of mathematical equations of regression models that optimally describe these dependencies. As a result of processing of experimental data, the ratio of alloying elements which can be used for

Abstract:

Iron-nickel alloy is an example of bimetallic nanostructures magnetic alloy, which receives intensive and significant attention in recent years due to its desirable superior ferromagnetic and mechanical characteristics. In this work, a unique starfish-like shape of an iron-nickel alloy with unique magnetic properties was presented using a simple, effective, high purity, and low-cost chemical reduction. There is no report on the synthesis of such novel shape without complex precursors and/or surfactants that increase production costs and introduce impurities, so far. The synthesis of five magne

Abstract:

Abstract Lead-free solders have been adopted widely due to the environmental and health concerns associated with lead. However, these alloys face several challenges that impact their performance and reliability in electronic applications, e.g. high melting temperature, decrease in mechanical properties, and formation of brittle intermetallic compounds [1]. The addition of nickel has the potential to improve the properties of lead-free solder alloys [2-4]. This study focuses on the addition of Ni into the solder alloy with varying nickel content (0.1 - 4 mass% Ni) using computational thermodyna

The paper investigates the microstructure and phase composition of nickel- and aluminum-based intermetallic alloys obtained using two-wire electron-beam additive manufacturing (EBAM). Relevance of the research is related to the widespread use of intermetallic alloys based on nickel and aluminum (mainly Ni3Al) in various high-temperature applications and the need to use modern production methods when creating machine parts and mechanisms from these alloys. Using EBAM, the billets from intermetallic alloys with different ratios of the content of main components were obtained. Change in concentra

Abstract:

The plasma paste boriding process was used for production of the borided layers on pure nickel and nickel-chromium alloys. The produced layers consisted of nickel borides only (in the case of nickel) or a nickel and chromium borides mixture (in the case Ni–Cr alloys). The objective of this investigation was to indicate the importance of the presence of chromium for corrosion resistance of non-borided alloys, as well as to indicate the influence of phase composition of borided layers on their corrosion resistance. Pure nickel was characterized by higher corrosion resistance, in comparison to th

Metal dusting of three centrifugal cast, heat-resistant alloys was investigated in an environment containing 80 vol% carbon monoxide (CO)+20 vol% H2 at 650, 750, and 850 °C for 500 h. One of the nickel-based alloys experienced localized metal dusting at 650 °C and pitting at 750 °C. Pitting occurred on another alloy at 650 °C. A third nickel alloy was the most resistant to metal dusting, but pitting occurred at 750 °C.

In this study, Cu-Sn alloys with varying compositions were synthesized using nickel sulfate as a structure-directing agent during electrodeposition. The crystalline structure of the alloys and the influence of nickel sulfate on the morphology were systematically investigated. The corrosion behavior of these alloys was examined in 3.5 wt.% NaCl and 0.1 M HNO3 solutions using kinetic potential polarization and electrochemical impedance spectroscopy (EIS) techniques.
