Abstract The widespread adoption of additive manufacturing (AM) in different industries has accelerated the need for quality control these AM parts. Some complex and labor-intensive challenges associated with qualification certification parts are addressed by modeling monitoring process conditions. Quantifying melt-track conditions remains a significant computational challenge due to large-scale differential between melt pool part volumes. This work explores novel point field (PF) driven...
Metal additive manufacturing (AM) processes produce heterogeneous microstructures, leading to significant uncertainty in mechanical behavior. Process-induced defects cause additional and can degrade performance, particularly for local like fatigue. However, time monetary costs impose constraints on using repeated experiments quantify this across the process parameter space. Applying quantification methods with computational materials simulations help alleviate these costs. In paper, a...
The objective of this work is to compare the performance uncoated micro end mills with coated using various pretreatments and diamond coatings. Testing conducted 300-um-diameter, two-flute, carbide cutting full-width slots in 6061-T6 aluminum. comparison these tools a robustness test where feed rate tool increased every 5 mm linear travel until catastrophic failure occurs. outcomes from tests are maximum chipload, therefore material removal rate, force experienced by tool. It has been...
Abstract Lötverbindungen aus NiCr 20 TiAl und X 8 CrCoNiMo 10 6 als Grundwerkstoffe Hartloten der Typen VH 950 (AuNi) NB 30 (NiCrSi 71 19 10) wurden in Leitungswasser, Schwefelsäure (5%) Meerwasser untersucht, zwar im Tauchversuch elektrochemisch. Die Korrosionsbeständigkeit ist danach abhängig vom Potentialunterschied zwischen den einzelnen Bestandteilen Lötverbindung jeweiligen Elektroylten. Nickellegierung mit dem Lot besitzen daher hohe Korrosionsbeständigkeit, während die Verbindungen...
In dem Aufsatz wird die generelle Anwendung von Aluminiumlegierungen im Schiffbau in Bezug auf Problematik Festigkeit, Fertigung und Korrosion betrachtet. Spezifisch das Problem der seewasserführenden Rohrleitungen aus eingegangen. Dazu werden Versuchsergebnisse vorgestellt, an längsnaht- rundnahtgeschweißten Rohren AlMg 4,5 Mn geschlossenen Kreislauf durchgeführt wurden. Application of aluminium shipbuilding – Corrosion, corrosion protection, strength and fabrication The general application...
