alkej-111	Hassan, Kharia Salman	خواص البنية المجهرية والميكانيكية لوصلات لحام الخلط الاحتكاكي لسبائك المنيوم متماثلة وغير متماثلة	2018	10	.pdf	application/pdf	3814	158	54	Therefore friction stir welded joints have amended Kharia Salman Hassan Al-Khwarizmi Engineering Journal, Vol. 14, No. 1, P.P. 19- 28 (2018) 20 mechanical qualities like tensile strength, ductility, hardness compering with fusion welded joints [5]., structure of weld, due to hard mechanical stresses shows three clear microstructural zones on the transverse cross section of the FSW joint, .these zones are a nugget, or stirred zone, thermo-mechanical affected zone (TMAZ), and a heat affected zone (HAZ) ,nugget zone NZ is a region through which tool pin passes and thus experiences both high deformation and heat treatment. Used Alloys Sheets of Aluminum alloys AA6061-T6 and AA2024T3 are used to produce dissimilar friction stir welded joints.	cache/alkej-111.pdf	txt/alkej-111.txt
