Interfacial Microstructures and Kinetics of Sn2.5Ag0.7Cu/Cu

Materials Science Forum, 2011
The interfacial microstructures and kinetics of low Ag content Sn2.5Ag0.7Cu/Cu solder joint were investigated by the X-ray diffraction, scanning electronic microscope and energy spectrum analysis during the isothermal aging. The results show that the interfacial microstructures of the Sn2.5Ag0.7Cu/Cu solder joint are composed of Cu3Sn and Cu6Sn5after ...

The Influence of Interfacial Energies on Igneous Microstructures [PDF]

, 2015
The thermal history of igneous rocks is encoded in their microstructures via the control by cooling rate on crystal growth. If temperatures remain close to the liquidus, with small undercoolings, growth rates are low and microstructures are strongly affected by constraints imposed by interfacial energies.

Microemulsion microstructure and interfacial curvature

Colloid & Polymer Science, 1994
The typical phase behavior of microemulsion systems undergoing phase inversion is briefly reviewed. As a model system H2O-n-octane-C12E5 is studied with various experimental techniques. The occurring microstructures are visualized by freeze fracture electron microscopy and the corresponding domain sizes are quantified by small-angle neutron scattering.

Interfacial characterization with wettability, microstructure and interfacial thermodynamics for Ti–Al/VN system

Metallurgical Research & Technology, 2019
Interfacial characterization, which includes wettability, interfacial microstructure and interfacial thermodynamics between VN substrate and Ti–Al molten alloy with different Al concentrations, was studied by the sessile drop method at 1758 K. The wettability between molten Ti–Al alloy and VN depends on alloy composition.

Interfacial microstructure of Ti3AlC2 and Al2O3 oxide scale

Scripta Materialia, 2006
The microstructural characteristics of the Ti(3)AlC(2)/Al(2)O(3) interface have been investigated by means of transmission electron microscopy (TEM). The orientation relationships (ORs) between the Ti(3)AlC(2) and the Al(2)O(3) oxide scale are shown to be (0001)Ti(3)AlC(2)parallel to(0001)Al(2)O(3) and [1120]Ti(3)AlC(2)parallel to[1210]Al(2)O(3) (OR-1);

Microstructure of the Pd–GaAs(001) interfacial reaction

Philosophical Magazine A, 1989
Abstract The Pd-GaAs(001) interfacial reactions after annealing treatments in vacuo have been investigated using cross-sectional transmission electron microscopy, X-ray energy-dispersive spectroscopy, X-ray diffraction and scanning electron microscopy. Our observations show that the reactions occur as the following processes: (1) from room temperature ...

Interfacial microstructure evolution in Pb-free solder systems

Journal of Electronic Materials, 2003
The Sn-3.5Ag and Sn-3.0Ag-0.5Cu ball-grid-array solder balls bonded onto Ni/Au metallization exhibited different interfacial morphology after both wetting and solid-state reactions. In contrast to the eutectic-SnPb solder system, both Pb-free systems showed higher solder-ball shear strength after annealing.

Interfacial microstructure of cenosphere fly ash/Al composites

Composite Interfaces, 2014
Lightweight aluminum matrix composites were fabricated by the pressure infiltrating molten pure Al or 6061Al into the packed preforms of hollow-structured cenosphere fly ash. The optical microstructure of the composites demonstrated a uniform distribution of the fly ash in the aluminum matrix and seldom infiltration of cenospheres.

Microstructural evolution and interfacial crystallography in Cr–Cr2Ta

Intermetallics, 2012
Abstract The microstructural features of a Cr–Ta alloy containing 10at% Ta have been studied in the as-cast and stress-relieved condition, and after long-term annealing at 1300 °C and 1500 °C. In the as-cast and stress-relieved state, the microstructure consisted of dendrites of the Cr 2 Ta Laves phase and a lamellar eutectic mixture of Cr(Ta) solid ...

Graphene-Induced Oriented Interfacial Microstructures in Single Fiber Polymer Composites

ACS Applied Materials & Interfaces, 2015
Interfacial interactions between the polymer and graphene are pivotal in determining the reinforcement efficiency in the graphene-enhanced polymer nanocomposites. Here, we report on the dynamic process of graphene-induced oriented interfacial crystals of isotactic polypropylene (iPP) in the single fiber polymer composites by means of polarized optical ...
