Oct 08, 2020 · During the soldering process, intermetallic phases such as Cu3Sn and Cu5Zn8 were formed at the interface between an Sn-Zn alloy and Cu substrate. Tensile strength and fracture elongation of solder (PDF) The SnZn (Tin-Zinc) system - ResearchGateOct 08, 2020 · During the soldering process, intermetallic phases such as Cu3Sn and Cu5Zn8 were formed at the interface between an Sn-Zn alloy and Cu substrate.

Characterization of the growth of intermetallic

Single shear lap joints were made with four different solders, Sn-Pb and Sn-Ag eutectic solders, and their composites containing about 20 vol.% in-situ Cu6Sn5 intermetallic phases about 38 micrometers in diameter. Two sets of experiments were performed:In the first set, all of the above four solder joints were aged at 150°C for periods ranging to 5000 h and the intermetallic growth was Crystals Free Full-Text Special Issue Intermetallic Nov 23, 2020 · Results of the simulation indicate that the alloying of the Nd 2 Fe 14 B intermetallic with Ce to x = 0.94 does not completely eliminate the negative effect of spin-reorientation phase transition on the residual magnetization of the (Nd 1x Ce x) 2 Fe 14 B intermetallic and slightly decreases the slope of magnetization reversal curve. High-Performance Nitrogen-Doped Intermetallic PtNi The density functional theory calculations suggest that the tensile strain introduced by the formation of an intermetallic phase and N-doping optimizes the binding of oxygenated species on the Pt surface and enable highly efficient electron transfer, leading to the enhanced ORR performance. This study offers an appropriate route for further

Identification of Surface Structures in Pt3Cr

A precise understanding of the catalytic surface of nanoparticles is critical for relating their structure to activity. For silica-supported PtCr bimetallic catalysts containing nominal Cr/Pt molar ratios of 0, 1.9, and 5.6, a fundamental difference in selectivity was observed as a function of composition for propane dehydrogenation, suggesting different surface structures. The formation of Intermetallic phase formation in MgAgNd (QE) and The intermetallic phase (designated phase) in the solution-treated microstructure of commercial magnesium alloy QE22 (Mg2.5Ag2.0Nd0.7Zr, wt%) has been investigated using scanning electron microscopy, electron diffraction, atomic-resolution scanning transmission electron microscopy (STEM), and thermodynamic modeling. Intermetallic phase formation in MgAgNd (QE) and The intermetallic phase (designated phase) in the solution-treated microstructure of commercial magnesium alloy QE22 (Mg2.5Ag2.0Nd0.7Zr, wt%) has been investigated using scanning electron microscopy, electron diffraction, atomic-resolution scanning transmission electron microscopy (STEM), and thermodynamic modeling.

Micropillar Compression Deformation of Fe-Zn Intermetallic

The deformation behavior of two of the five Fe-Zn intermetallic phases (, 1, 1k, 1p and ), which are formed in the coating layer of galvannealed steel, has been investigated through uniaxial compression tests for single-phase polycrystalline micropillars. The phase is ductile to some extent while the 1 phase is brittle. These Microstructural Assessment of a Multiple-Intermetallic 1 day ago · At room temperature, the molar fractions of different intermetallic phase structures calculated from equilibrium solution thermodynamics calculations are 50% Al 13 Fe 4, 37% Al 13 Cr 2, 11% FCC/L1 2, and 2% BCT/DO 22. Other intermetallic phases, such as Al 4 Cr and Al 11 Cr 2, are predicted to stabilize Ordered Intermetallic Pd3Bi Prepared by an The resulting phase-converted ordered intermetallic Pd3Bi exhibits 11 times and 3.5 times higher mass activity and high methanol tolerance for the oxygen reduction reaction compared with Pt/C and Pd/C, respectively, which is the highest reported for a Pd-based catalyst, to the best of our knowledge.

Realization of the kagome spin ice state in a frustrated Mar 13, 2020 · Structure and magnetometry measurements. HoAgGe is one of the ZrNiAl-type intermetallics with space group P-62m, which is noncentrosymmetric. In particular, Zr sites in the ab plane form a distorted kagome lattice (26, 27) ().The distortion is characterized by opposite rotations of the two types of triangles in the kagome lattice by the same angle (~15.58° in HoAgGe) around the c axis. Some aspects of the precipitation of metastable Some aspects of the precipitation of the metastable intermetallic phases and in the commercial nickel base superalloy, INCONEL 718, have been investigated over a wide range of aging temperatures. It has been confirmed that the spherical particles and the ellipsoidal particles evolve predominantly through homogeneous nucleation.

Ternary intermetallic compounds in AuSn soldering

The intermetallic compound AuSn is essential for the wetting of Au-rich AuSn solders. On the addition of In or Sb, pseudo-binary compounds AuSn1xInx (x 0.33) and AuSn1ySby (y 0.17) are formed. Both adopt the AuSn structure type (P63/mmc, Z = 2). This single-crystal X-ray diffraction study reveals that there is an absence of superstructure ordering upon long-time annealing (years).
