Abstract

Distinct AZ80A-Mg alloy with AA6061-Al alloy plates were joined using friction stir welding and investigation regarding the weld features of the fabricated joints, related to microstructural attributes and mechanical properties was carried out by employing distinctive tool rotational speeds (1600, 1400, 1200, 1000 and 800 rpm). Tool possessing cylindrical pin with tapered profile was employed at constant traverse speed of 30 mm/min and was inserted towards AA6061 alloy plate at 0.5 mm offset distance. Experimental observations revealed that employment of tool rotational speed of 1200 rpm have generated ideal amounts of frictional heat, which have softened the ingredients of both the parent metals and have contributed for the transition of the grains into dynamically recrystallized, finely refined structures being distributed evenly in nugget zone. Moreover, this joint exhibited a tensile strength of 224 MPa (nearly 77.78 % of the tensile strength of AZ80A and 72.26 % of AA6061 alloy). Presence of river like patterns, rifts, tear crinkles at the middle portions of fractured surfaces, announced the brittle category of fracture of the flaw free joint and exhibited fracture at the horizon of the thermomechanically influenced zone and the nugget zone on retreatment side, where the warped structures have fused together.

Kurzfassung

Platten aus einer AZ80A-Mg- und einer AA6061-Al-Legierung wurden mittels Rührreibschweißen (Friction Stir Welding, FSW) gefügt. Die bei unterschiedlichen Werkzeugdrehzahlen (1600, 1400, 1200, 1000 und 800 1/min) erzielten Gefügemerkmale und mechanischen Eigenschaften der Verbindungen wurden untersucht. Das Werkzeug mit einem zylindrischen Stift mit konischem Profil wurde mit einer konstanten Verfahrgeschwindigkeit von 30 mm/min eingesetzt und mit einem Versatz von 0,5 mm in die Platte aus der Legierung AA6061 eingeführt. Bei den bei 1200 1/min hergestellten Verbindungen entwickelte sich eine optimale Menge an Reibungswärme, bei der die Bestandteile beider Grundwerkstoffe erweicht wurden und die zur Umwandlung der Körner zu dynamisch rekristallisierten, einachsigen Strukturen beigetragen hat, die gleichmäßig über den gesamten Bereich der Schweißlinse verteilt sind. Die Verbindung hatte eine Zugfestigkeit von 224 MPa, nahezu 77,78 % der Zugfestigkeit von AZ80A- und 72,26 % der Zugfestigkeit der AA6061-Legierung. Das Vorhandensein flussartiger Muster, Spaltungen und Rissverwerfungen in den mittleren Bereichen der Bruchflächen weisen auf ein sprödes Bruchverhalten der fehlerfreien Verbindung hin und wies einen Bruch am Horizont der thermomechanisch beeinflussten Zone und der Nuggetzone auf der Rückzugsseite auf, wo die verzogenen Strukturen miteinander verschmolzen sind.
