In this paper, results of an investigation on the strain hardening responses of superalloy MP35N with two average grain sizes of 38 and 1 μm, during room temperature tensile testing are reported. The microstructural evolution of the deformed samples was studied using optical and transmission el...

Ag core MP35N (Ag/MP35N) wire has been used in lead electric conductor wires in the medical device industry for many years. Recently it was noticed that the combination of silver and MP35N restricts its wire drawing process. The annealing temperature in Ag/MP35N has to be lower than the melting ...

Systematic research has been undertaken on the effects of deformation and aging on the mechanical properties and microstructures of MP35N alloys. A relationship among the aging time, aging temperatures and mechanical properties has been established and the optimum aging conditions were criticall...

This paper addresses the fracture properties of commercially cold-drawn (53%) MP35N (35% Co, 35% Ni, 20% Cr, and 10% Mo) in both the cold-worked and the cold-worked and aged conditions. MP35N is a superalloy that exhibits a remarkable combination of high strength (about 2 GPa) and high fracture ...

The deformation response of low Ti (

In a previous paper, the microstructure, monotonic, and cyclic response of as-drawn ~100 μm diameter MP35N low-Ti alloy wire were presented and discussed. In this sequel paper, the effects of annealing the same cold-drawn wire on microstructure and mechanical properties are examined. Specifical...

Multiphase Co-35Ni-20Cr-10Mo alloy MP35N® is a high strength alloy with excellent corrosion resistance. Its applications span chemical, medical, and food processing industries. Thanks to its high modulus and high strength, it found applications in reinforcement of ultra-high field pulsed magnets...

MP35N (35 % Co, 35 % Ni, 20 % Cr, 10 % Mo; weight fraction) in the form of thin wires (100 µm diameter) is commonly used as conductors in cardiac leads, which require excellent corrosion resistance and high fatigue strength, in particular in the very-high cycle fatigue (VHCF) regime. This becom...

In this paper, a novel collector, 2-ethyl-2-hexenoic hydroxamic acid (EHHA) was prepared and characterized by elemental analysis, infrared, 1H NMR, 13C NMR and mass spectra. The flotation performance and adsorption mechanism of EHHA to ilmenite were investigated by micro-flotation tests, density...

For more than a hundred years, extraction with ethyl ether has been the most used method for synthetizing H3PW12O40. However, the use of ethyl ether as the extraction agent faced many problems, such as strict regulation by public safety and environment authorities, poor operating environment, si...

The protonation of polyemeraldine base (PANI) by diesters of phosphoric acid was studied. Three esters were investigated, namely bis(2-methylpropyl) hydrogen phosphate (DiBHP), bis(2-ethylhexyl) hydrogen phosphate (DiOHP) and its non-branched analogue, bis(n-octyl) hydrogen phosphate (DnOHP). It...

Adjacent lanthanides are among the most challenging elements to separate, to the extent that current separations materials would benefit from transformative improvement. Ordered mesoporous carbon (OMC) materials are excellent candidates, owing to their small mesh size and uniform morphology. Her...

A novel extractant heptylaminomethyl phosphonic acid 2-ethylhexyl ester (HEHHAP, abbreviated as H2L2) was synthesized for the extraction and separation of trivalent rare earths (REs: La ~ Lu, plus Y) from chloride medium. The results showed that the extraction of heavy REs by HEHHAP was higher t...

The conventional rare earth solvent extraction equipments have many problems such as long mixing time, low processing capacity, large factory area occupation, high energy consumption and so on. In order to solve the problems, many types of equipments were brought out. In this work, studies were ...

A new solvent extraction system of extracting La(III) with 2-ethylhexyl phosphoric acid-2-ethylhexyl ester (P507) has been investigated to intensify the extraction process in microreactor, and solve the problems like long mixing time, low processing capacity, large factory area occupation, and h...

By using membrane dispersion micro-extractor, Ce(III) solvent extraction experiments were conducted. Cerium chloride solution with certain acidity was used as aqueous phase and 2-ethylhexyl phosphoric acid-2-ethylhexyl ester (EHEHPA) kerosene solution as organic phase. The effects of system phys...

A process to recover rare earth (RE) metals from spent fluid catalytic cracking (FCC) catalysts by solvent extraction was studied, using saponified 2-ethylhexyl phosphoric acid-2-ethylhexyl ester (EHEHPA or P507). The recovery process involved three steps: (1) leaching REs (mainly lanthanum and ...

Solvent extraction kinetics of Sm (III), Eu (III) and Gd (III) from hydrochloric acid have been focused on using 2-ethylhexyl phosphoric acid-2-ethylhexyl ester (P507) with Anordning for Kontinuerlig Undersokning av Fordelningsfaktore vid Vatske Extraction (AKUFVE). Compared with the conventiona...

Cobalt silicate hydroxide (Co3[Si2O5]2[OH]2) was prepared by chemical method for use in electrochemical capacitors.
