Abstract

Friction stir process (FSP) is a solid state process in which many parameters play important roles. Al 7075 is one of the strongest alloys. In this paper the effect of the traverse and rotational speed on the Mechanical properties of Al 7075 are investigated in Submerged and ambient conditions. The Friction stir process is done with a threaded pin. The pin diameter, pin length and diameter of the shoulder were 8, 5 and 18 mm respectively. The experimental results showed that the normal and Submerged Friction stir process with optimum parameters can increase strength and elongation of Al7075. In the Submerged and normal Friction stir process tensile strength and elongation were increased 14. 85, 128. 57, 11. 71 and 138. 1 percent respectively. In most of the specimens Vickers micro hardness was increased regard to base metal. The Submerged Friction stir process generally showed better results than the normal Friction stir process. In Submerged Friction stir process the maximum temperature was reduced about the 60 percent in comparison of the normal Friction stir process.
