Description
Summary:Friction stir welding is a comparatively new method for assembly of metals. Study similar alloy of AA 2040were done by FSW process and also study effects behavior of FSW on some mechanical properties (tensile, impact energy and microhardness). Studied were parameters (FSW) like speeds of transverse (116,189 mm/min) and speeds of rotational (450,560 rpm) which effects on mechanical micro structure and properties. Indicates of results of the tensile test that which increase tensile strength (316 MPa )by decreases speeds of rotational and increases of welding speeds, at parameters of the welding (560 rpm and 116 mm/min) with 71% efficiency. FSW caused small differences to micro hardness of the material. Enhancement energy absorbed from (2.5)J at substrate alloy with compared(3.7)J in FSW. The microstructure was greatly refined, after FSW.
