The repair of high strength, performance 7075 aluminum alloy is essential for a broad range aerospace and defense applications. However, it challenging to implement using traditional fusion welding-based approaches, owing hot cracking void formation during solidification. Here, the use an emerging solid-state additive manufacturing technology, friction stir deposition, explored volume damages such as through -holes grooves in alloy. Three experiments have been conducted: double through-hole...
Laser powder bed fusion is a promising technology for local deposition and microstructure control, but it suffers from defects such as delamination porosity due to the lack of understanding melt pool dynamics. To study fundamental behavior pool, both geometric thermal sensing with high spatial temporal resolutions are necessary. This work applies integrates three advanced technologies: synchrotron X-ray imaging, high-speed IR camera, high-spatial-resolution camera characterize evolution...
Given the challenges in feed material supply and quality control, metal additive manufacturing has rarely been implemented austere environments, especially underwater. This paper explores underwater operation potential of an emerging solid-state technology: friction stir deposition, wherein feeding bonding are enabled by mechanical forces with minimal influences from water. It is demonstrated that deposition 304 stainless steel can be successfully performed print head substrate immersed High...
Friction stir welding (FSW) produces a gradient microstructure with distinct metallurgical zones. The present study focuses on characterizing the fracture behavior during uniaxial loading across thick‐section FSW joint in nonheat‐treatable 5083 aluminum alloy. hardness variation is linked to microstructural features weld zones through correlative microscopy. Notably, heat‐affected zone (HAZ) exhibits lower of 75 HV, while thermomechanically affected (TMAZ) and (SZ) display around 79HV. A...
Abstract
Abstract: Optical methods that yield displacement or strain fields are now emerging significantly in the mechanical sciences. At Research Center on Tools, Materials and Forming Processes (CROMeP) at École des Mines d'Albi, a binocular stereovision system has been developed can be used to measure: (a) three‐dimensional (3D) shape of static object, (b) surface strains an object undergoing some 3D thermal stress. In this paper, application technique investigate behaviour ceramic refractories...
