Oxide Modified Iron in Electron Beam Powder Bed Fusion - From Processability to Corrosion Properties
(2022-03-07)
Additive manufacturing (AM) processes are not solely used where maximum design freedom meets low lot sizes. Direct microstructure design and topology optimization can be realized concomitantly during processing by adjusting the geometry, the material composition, and the solidification behavior of the material considered. However, when complex specific requirements have to be met, a targeted part design is highly challenging. In the field of biodegradable implant surgery, a cytocompatible material of an application-adapted ...

On the Challenges toward Realization of Functionally Graded Structures by Electron Beam Melting—Fe-Base Shape Memory Alloy and Stainless Steel
(ASTM International, 2020-09-22)
In the present study, an iron-manganese-aluminum-nickel (Fe-Mn-Al-Ni) shape memory alloy was processed on an austenitic steel (AISI 304) build platform by electron beam melting in order to study the feasibility of realizing functionally graded structures consisting of two different materials (i.e., a functional and a structural material). Compression specimens consisting of the processed shape memory alloy and the austenitic build platform in equal parts were investigated. The microstructure was analyzed in the ...

Investigation of residual stresses in polypropylene using hot plate welding
(2020-08-05)
During the cooling process of the molten material, residual stresses appear because the reduced volume of the cooled material cannot fully fill the space formerly occupied by the molten material. The morphology in and around the weld is formed by different factors depending on the material and process parameters. Different morphological structures relate to different mechanical properties. The process parameters and the welding results including morphology and residual stress are linked together. In this article, ...

The potential of mangrove as a food source in Riau
(2023-12-28)
Mangrove fruit has been utilized as a food by people in several regions in Indonesia, especially as traditional food. Information about the potential and benefits of mangrove fruit is still limited. There is not much information regarding physico-chemical properties of mangrove fruit as a potential food source. This study aims to gather and review various scientific information related to the potential of mangrove fruit and its use as foodstuff. This information can be used as a basis to conduct further research ...

Community-Resilience und Bürgerbeteiligung
(2023)
Ziel dieser Arbeit ist es, anhand der Forschungsfragen dieser Grundlagenstudie einen Zusammenhang von Community Resilience und Bürgerbeteiligung nachzuweisen und den Weg zur weiteren Diskussion multipler Resilienz bzw. multiresilienter Gesellschaften zu eröffnen. Im theoretischen Teil der Arbeit wurden anhand der untersuchten Fachliteratur in ausgewählten Richtungen der Resilienzforschung keine Verbindungen zur Bürgerbeteiligung festgestellt. Ebenso zeigen die untersuchten Handbücher und Leitlinien zur Bürgerbeteiligung ...

Effects of blending poly(lactic acid) and thermoplastic polyester polyurethanes on the mechanical and adhesive properties in two-component injection molding
(2022-09-16)
One possible way to increase the use of bioplastics and thus contribute to a more resource-efficient and sustainable economy is to broaden the application range of such bioplastics. Poly(lactic acid) (PLA) is a promising and commercially available bio-based and biologically degradable polymer, which exhibits a high strength and stiffness but is very brittle. Blending with other polymers can lead to an enhancement of the ductility of the PLA. The goal of this work was to show that blending of PLA with a bio-based ...
