The number of IMCs in the Sn-3.5Ag-1.0Cu-0.4Mg solder is more than that in the Sn-3.5Ag-1.0Cu-0.2Mg.
The interface for Sn-3.5Ag-1.0Cu solder, Sn-3.5Ag-1.0Cu-0.2Mg solder, and Sn-3.5Ag-1.0Cu-0.4Mg solder were shown in this figure.
(2) In the case of Sn-3.5Ag-1.0Cu-0.2Mg solder and Sn-3.5Ag-1.0Cu-0.4Mg solder, the size of β-Sn grain was similar with that in the case of Sn-3.5Ag-1.0Cu solder.

Fig. 1.
As for the complexed film, the C=N band at around 1629 cm-1 in the Schiff base film shifted to 1607 cm-1 [6].
The result showed C18TSB formed 1:2 type complex with Zn(II) ions.

Here, the excitation wavelength was 464 nm and the integrated intensities of I0 and I1 were calculated at the wavelengths between 450−479 nm and that of I2 was at 479−750 nm.
Accordingly, the ηint value was calculated by Eq. (1).

Results and discussion
Figure 1 shows the X-ray diffraction patterns of the starting and as-milled Mg55Y15Cu30
powders as a function of milling time.
The as-milled Mg55Y15Cu30 powders were hot pressed at 453 K under a pressure of 1.2GPa for 30 minutes.
The high pressure involved during consolidation can thus prolong the existence of amorphous phase inside Mg55Y15Cu30 powders. 20 30 40 50 60 70 80 10h 7.5h 5.0h 2.5h 1.0h 0.0h Relative Intensity (arb. units) 2θ Y Mg Cu 400 500 600 700 10h 7.5h 5.0h 2.5h 1.0h Extho. heat flow (arb. units) Temperature ( K ) T g442K T x 478K Fig.1 X-ray diffraction patterns of mechanically alloyed Mg55Y15Cu30 powders as a function of milling time.
