Sokovic et al. [3] reported that, when the cutting speed increased, the contact zone temperature increase which leads to a substantial reduction in tool life.
El-Bestawi et al. [4] found that tool life decreased with increased cutter diameters as the radial depth of cut increased.
Krain et al. [5] reported that an increase in immersion ratio resulted in an overall reduction of tool life.
Haron et al.[8] reported that there was a strong bonding between the chip and tool material.

Under this situation, the effect of fragmentation on α-Al matrix reduced.
And the α-Al cells in part A are more coarser than that in part B.
Slip bands are formed in the Al dendrite at the crack tip and cracks propagate along with the eutectic phases in the α-Al matrix.

An experimental study of orthogonal cutting of SiCp/Al composites: Cutting forces analysis Shutao Huang a, Li Zhou b, Jinlei Wang c 1School of Mechanical Engineering, Shenyang Ligong University, Shenyang 110159, China asyithst@yahoo.com.cn, blizhou@imr.ac.cn, cjl_wang@126.com Keywords: SiCp/Al composites; Orthogonal cutting; Cutting force.
Machining of SiCp/Al composites has been considerably difficult because the extremely abrasive nature of SiC reinforcements causes rapid tool wear.
SiCp/Al composites, (a) microstructure, (b) workpiece morphology.
From the figures, it can be observed that the cutting force decreases by increasing cutting depth during machining of SiCp/Al composites.

Cheng et el. [17] explored the direct bonding of Cu/Cu under thermal compression using surface creep model.
On the contrary, Zhang et el. [22] reported decrease in the hardness in the joint interface as compared to their parents metals.
Sebastian et el. [21] revealed that the bondign stregnth increased from 50-180 MPa with increase in bonding temperature from 750-1000◦C.
Similarly, Sebastian et el. [24] indicated that the bonding strength increases with the temperature up to 850°C.

The basis for evaluating the critical size of the corrosion pit is the Kitagawa-Takahashi diagram modified by El Haddad (KTHD).
This graph was completed by El Haddad, Topper and Smith [6] with another ‘El Haddad curve’ to which the Kitagawa lines create asymptotes.
Thus for the El-Haddad line is valid: Ds(a) = (DKth)/(Y(p.
