fatigue properties of steel to aluminum transition joints
Examples of steel subjected to fatigue Welded joints joining components of built- up members Section 4 Longitudinal filled welded end connections Section 5 Welded joints transverse to direction of stress Section 6 Base metal at welded transverse member connections Effect of Welding Consumables on Fatigue Performance of Feb 01, 2009 · The superior mechanical properties (higher yield strength and hardness) and preferred microstructures in the weld metal region (acicular ferrite) are the reasons for superior fatigue performance of the joints fabricated using low hydrogen ferritic steel consumables than the joints fabricated using austenitic stainless steel consumables.
Dec 18, 2012 · Butt joints made of 5-mm high-strength steel S960 were dynamically tested to determine the influence of filler metal and shielding gas on fatigue. To elucidate the local properties at the most damaged weld toe region, extensive fracture analysis, topographic measurements, residual stress tendencies, and evaluation of macro-hardness were performed. Effects of rotational speed on microstructure and May 19, 2020 · The dissimilar welding of AlZnMg alloy (7005) plates and AlMg alloy (5083) rods was conducted using the inertia friction welding process. The effect of rotational speed during welding on the microstructure and mechanical properties of the joints was then investigated. The results indicate that under lower rotational speeds, a transition layer was formed at the interface that reduced International Journal of Fatigue Vol 139, October 2020 Fatigue strength assessment of TIG-dressed ultra-high-strength steel fillet weld joints using the 4R method H. Mettänen, T. Nykänen, T. Skriko, A. Ahola, T. Björk Article 105745
Sep 20, 2019 · 6082 high-strength aluminum alloy was welded by metal inert gas arc welding (MIG), and the welded joint and high-cycle fatigue result were applied to the welded joint and the base metal. The result found that the precipitation and dissolution of the strengthening phase changed the hardness of the welded joint.Fatigue damage study of cold metal transition fusion In the high-stress condition, the cyclic hardening induced by the ratcheting strain is much stronger than that in the lower stress condition, which improves the fatigue life of the materials. ABSTRACT An aluminium/steel CMT-welded joint is mainly composed of fusion zone (FZ), interfacial intermetallic compound (IMC) zone, and heat-affected zone (HAZ).
