Webb6 jan. 2024 · (iv) Finally, although the fracture surfaces and failure locations of the joint soldered with 400 ms and 800 ms vibration times show similar characteristics, they are influenced by the aging time. In order to accelerate the growth of interfacial intermetallic compound (IMC) layers in a soldering structure, Cu/SAC305/Cu was first ultrasonically … The clinical presentation varies depending on the stage of the disease from mild swelling to severe swelling and moderate deformity. Inflammation, erythema, pain and increased skin temperature (3–7 degrees Celsius) around the joint may be noticeable on examination. X-rays may reveal bone resorption and degenerative changes in the joint. These findings in the presence of intact ski…

The effect of rotation speed on joint formation, intermetallic compounds (IMCs), and failure load of the welded joints was mainly studied. The results showed that dissimilar Al/Mg alloys could be successfully joined by RFSSW, and defect-free joints were … cubs right fielder 2019
