The activities of gold and nickel in solution at these temperatures exhibited large positive deviations from Raoult's law. It was possible to measure metastable activities of nickel, which were obtained by quenching the galvanic cell to a temperature in the miscibility gap. The alloy system is ...
Low-alloy and constructional nickel-containing steels have been excluded on two grounds. To do them justice would require excessive space and, in addition, their applications differ generally from these of the materials under discussion. On the other hand, nickel-containing stainkss steels have been...
The NiTi-Ag alloys showed low silver recovery rate for the cast alloy, due to silver's low evaporation temperature, and low silver solubility in nickel–titanium. Sil 展开 关键词: shape memory superelasticity nickel&ndash titanium alloy silver corrosion resistance ...
The need for nickel-base powder metallurgy (PM) superalloy turbine discs is becoming increasingly evident. With the eventual aim of improving thrust-to-weight ratio of aeroengines for power generation, well integration of significantly high strength, high damage tolerance and high-temperature capability...
Nickel/chromium alloys with over 30% chromium have a two-phase structure including ?-nickel and a-chromium. Since the a-chromium phase is brittle, the ductility of the alloy decreases with an increase in chromium content.Table 2 illustrates the properties of certain binary alloys. The addition ...
By means of thermodynamic calculation, OM, SEM, TEM and X-ray diffraction, microstructural stability was investigated on the new nickel-based superalloy, INCONEL alloy 740. Some mechanical properties of the new alloy were also studied. The results indicated that the microstructure of this alloy mai...
The properties of nickel-iron deposits were investigated, and the following conclusions were drawn: (1) The stress was rapidly decreased by the addition of a very small amount of saccharin. (2) The stress was increased with the increase in concentrations of urea and NH4HF2. (3) The stress...
Specimen blanks of additive-manufactured nickel Alloy 625 and Ti-6Al-4V were produced by the laser powder-bed-fusion process (L-PBF) with the principal test axis in both the Z direction (parallel to the build direction) and the X-Y direction (perpendicular to the build direction). The high...
Relationship (1) has been estimated just by averaging of Hugoniots of nickel, cobalt, stainless-steel [11] and Co–Ni alloy [12] which actually are very close to each other. Discussion The experiments presented in this work do not confirm the spall strength increase and the transition from ...
