The Ti element in Ti substrate continuously diffused into Ti[Al.sub.3] layer and reacted with it under the concentration gradient driving forces, and then intermetallics
Ti[Al.sub.2], TiAl, and [Ti.sub.3]Al were formed.
Combining XRD analysis and microstructure observations, we can conclude that porous PdAl intermetallics
were successfully prepared.
Stir zone which indicate the intermetallic
region which is shown in the figure 4(a).The copper particles were present in the aluminium side of the weld nugget.
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
Higher laser power of 82 W develops coralline-like feature (Figure 7) from ultrafine intermetallics
such as [Al.sub.13][Fe.sub.4] and [Fe.sub.3]Al (Figure 7(c)).
Over the years, a number of studies have been carried out to assess the effect of Cu content and the distribution of second phase intermetallic
particles on the corrosion behavior of Al-alloys.
Key words: lead-free solder, intermetallic
compound, formation, growth, annealing
Also, ImAg does not form SnCu intermetallic
growth during storage as 100%-Sn finishes do.
That's why it would be logical to expect change in structure of the layers and, as a result, differences in synthesis processes of intermetallics
in case of using different methods of production of laminated materials.
As for TiAl intermetallics
, they possess good high-temperature (700[degrees]C) oxidation resistance and low cost (with the addition of aluminum [Al]) apart from the low density and high specific strength.
