One of the most recent studies on dry machining of T6061 aluminium alloy was performed by Tasnim et. al. [8], but no research has been done particularly on dry machining of T6061 Aluminum alloy using Si3N4 tools.
Furthermore, Si3N4 cutting tool was found to have better wear resistance when compared to Titanium Nitride (TiN) and Titanium Carbonitride (TiCN) coated tools from a recent research done by Tasnim et. al. (2012) for the machining of T6061 Aluminium alloy in dry and wet conditions.

Because the earthquakes in Constantine’s “tell” are frequent, so the seismic zoning map prepared by the Algerian territory (CRAAG), and Bezzeghoud et al. 1996[10], shows that our study area is located in the area of seismic hazard means is characterized by active seismicity, with maximum intensities (between IX and X) of magnitude but moderate (3 to 6) on the Richter scale (Fig.5).
Fault of Ain ​​Smara [12] Many events that shook Constantine city and the east of Algeria, the earthquake of 1985 is considered the famous and largest seismic event in eastern of Algeria with a magnitude M =5.8, This earthquake has killed five people and injured 300 people, and there are several old buildings damaged, the most significant damage was recorded in the region of El-Aria, the intensity was measured at I = VIII (MSK) in this region [13].

A) Effect of Heating Rate: Heating and Quenching: A striking aspect of the grain growth observed is that there is negligible difference between the grain sizes for 100 and 1000◦C/s heating rates, which is supported by the work of Grossmann [12] and Tobian et al [13].
