., KE-1, L-64, TX-15, and EL-40.
EL-40 is castor oil polyoxyethylene ether.
Dynamic viscosity variations of TX-15 and EL-40 aqueous solutions are plotted in Fig. 1 (c) and Fig. 1 (d), respectively.
However, shear thinning effect can be seen for some conditions: KE-1 aqueous solution at 100℃, higher concentrations of L-64 at 75℃ and 100℃, TX-15 at 100℃, and EL-40 at 100℃.

The strong bond between the SiC substrate and Zn-Al-Mg solder is attributed to the mass transfer of SiO2 into Zn-Al-Mg by induced cavitation erosion.
Chemical composition of experimental solder Zn [wt. %] Al [wt. %] Ag [wt. %] Zn-Al-Ag 88 6 6 To determine the melting point of soldering alloy, the DSC analysis was employed.
The dilution of Al to solder was observed on the side of MMC substrate.

Abstract: For the purpose of investigating the surface defects on the machined surface in high speed milling of SiCp/Al Composites, the high speed milling experiments were performed on the precision milling machine (ops650).The machined surface was observed and measured by the OLS3000 Confocal Laser Scanning Microscope.
The past research on the machined surface micro-topography of SiC/p Al composites are mainly concentrated on the surface roughness, micro- hardness, residual stress and the chip formation mechanism.
To investigate the surface defects is necessary to adequately characterize the machined surface of SiC/p Al composites.
In this paper, the types and formation mechanisms of machined surface defects of SiC/p Al composites are investigated.
