Stir zone which indicate the intermetallic
region which is shown in the figure 4(a).
For revealing the effect of welding speeds on the size, shape, and distribution of intermetallic
particles, a scanning electron microscopy (SEM) with x-ray energy dispersive spectroscopy (EDS) system was utilized to verify such effect.
In order to further extend the future potential of these innovative intermetallic
materials, more applications in automotive and aero engines as well as other areas must be identified.
These I3-Sn particles always solidify at the interfaces of a-AI/Si or a-AUFe-rich intermetallics
Key words: lead-free solder, intermetallic
compound, formation, growth, annealing
As far as formation of intermetallics
in systems of this kind is result of reaction diffusion , one may assume that sequence of phase transformations is determined not just by thermodynamics, but also by diffusion kinetics.
The oxidation kinetics of bare Ti-48Al intermetallics
follows linear law at both temperatures.
BGA SAC joint fragility has been attributed to inconsistent plating quality of the copper pad, (4) Kirkendall void formation, (5) low solder ductility and intermetallics
The NIST Structural Database (NSD) contains crystallographic and atomic positional information for metallic crystalline substances, including alloys, intermetallics
, and minerals.
Friable manufactured diamond abrasives, however, can grind intermetallics
without cracking because of their sharp cutting edges and high wear resistance.
Brazing of nickel, ferrite and titanium-aluminum intermetallics
It is generally accepted, that intermetallics
in particular low cost FeAl offer outstanding material properties.
