Recent studies have shown the change of microstructure during hot-bending in uniaxial specimens made AZ31B alloy. They also investigated influence changed on quasi-static and cyclic material behavior under stress states. However, fatigue hot-bent structural components which a multiaxial inhomogeneous state occurs are still lacking. For this purpose, novel V-shaped specimen was developed, three ...

The corrosion behavior of AZ31B Mg alloy exposed to Ringer’s, phosphate-buffered saline (PBS), Hank’s, and simulated body fluid (SBF) solutions for 4 days was investigated using electrochemical impedance spectroscopy (EIS), potentiodynamic polarization, weight loss, surface characterization. Changes in rates with immersion time determined by loss measurements were compared EIS data determine th...

Abstract Interfacial structure greatly affects the mechanical properties of laminated plates. However, critical material that impact interfacial morphology, appearance, and associated bonding mechanism explosive welded plates are still unknown. In this paper, same base plate (AZ31B alloy) different flyer metals (aluminum alloy, copper, stainless steel) were used to investigate morphology struct...

Hybrid wire arc additive-milling subtractive manufacturing (HWMM) is an effective way to improve the quality of complex metal components, but difference in properties aluminum alloy and magnesium fabricated by HWMM has been not addressed. In paper, differences deposition accuracy tensile anisotropy between Al5Si Al AZ31B Mg alloys were studied using method. Under optimal parameters, minimum sur...
