  • Contact geometry modification of friction-welded semi-finished products to improve the bonding of hybrid components 
    Behrens, Bernd-Arno; Uhe, Johanna; Petersen, Tom; Nürnberger, Florian; Kahra, Christoph; Ross, Ingo; Laeger, René (Basel : MDPI AG, 2021)
    To improve the bond strength of hybrid components when joined by friction welding, specimens with various front end surface geometries were evaluated. Rods made of aluminum AA6082 (AlSi1MgMn/EN AW-6082) and the case-hardening ...
  • Fracture Resistance of Repaired 5Y-PSZ Zirconia Crowns after Endodontic Access 
    Greuling, Andreas; Wiemken, Mira; Kahra, Christoph; Maier, Hans Jürgen; Eisenburger, Michael (Basel : MDPI, 2023)
    This study analyzed the fracture load before and after a chewing simulation of zirconia crowns that were trepanned and repaired using composite resin. Overall, 3 groups with 15 5Y-PSZ crowns in each group were tested. For ...
  • Hot forming of shape memory alloys in steel shells: formability, interface, bonding quality 
    Gerstein, Gregory; Kahra, Christoph; Golovko, Oleksandr; Schäfke, Florian; Klose, Christian; Herbst, Sebastian; Nürnberger, Florian; Maier, Hans Jürgen (Heidelberg : Springer, 2021)
    Metal forming of shape memory alloys (SMA) can be challenging since these are very often brittle due to their intermetallic character. However, formability is often needed not only for realising the desired geometry but ...
  • Investigations on Additively Manufactured Stainless Bearings 
    Coors, Timm; Faqiri, Mohamad Yusuf; Saure, Felix; Kahra, Christoph; Buedenbender, Christoph; Peddinghaus, Julius; Prasanthan, Vannila; Pape, Florian; Hassel, Thomas; Herbst, Sebastian; Nuernberger, Florian; Wester, Hendrik; Uhe, Johanna; Breidenstein, Bernd; Denkena, Berend; Behrens, Bernd-Arno; Poll, Gerhard; Maier, Hans Juergen (Basel : MDPI, 2022)
    Additive manufacturing with multi-material design offers great possibilities for lightweight and function-integrated components. A process chain was developed in which hybrid steel–steel-components with high fatigue strength ...
  • Ion Beam Processing for Sample Preparation of Hybrid Materials with Strongly Differing Mechanical Properties 
    Barienti, Khemais; Kahra, Christoph; Herbst, Sebastian; Nürnberger, Florian; Maier, Hans Jürgen (Heidelberg : Springer, 2020)
    For studies of the interface zone of metallic composites with significantly differing mechanical properties across the interface, high-quality sample preparation is paramount. In particular, the analysis of the composition ...
  • Microstructural evolution and mechanical properties of hybrid bevel gears manufactured by tailored forming 
    Behrens, Bernd-Arno; Chugreeva, Anna; Diefenbach, Julian; Kahra, Christoph; Herbst, Sebastian; Nürnberger, Florian; Maier, Hans Jürgen (Basel : MDPI AG, 2020)
    The production of multi-metal bulk components requires suitable manufacturing technologies. On the example of hybrid bevel gears featuring two different steels at the outer surface and on the inside, the applicability of ...
  • Non-destructive Evaluation of Workpiece Properties along the Hybrid Bearing Bushing Process Chain 
    Fricke, Lara Vivian; Thürer, Susanne Elisabeth; Kahra, Christoph; Bährisch, Susanne; Herbst, Sebastian; Nürnberger, Florian; Behrens, Bernd-Arno; Maier, Hans Jürgen; Klose, Christian; Barton, Sebastian (New York, NY : Springer, 2022)
    To combine the advantages of two materials, hybrid bulk metal workpieces are attractive for subsequent processes such as metal forming. However, hybrid materials rely on the initial bond strength for the effective transfer ...
  • Ontology-Based Documentation of Quality Assurance Measures Using the Example of a Visual Inspection 
    Sheveleva, Tatyana; Herrmann, Kevin; Wawer, Max Leo; Kahra, Christoph; Nürnberger, Florian; Koepler, Oliver; Mozgova, Iryna; Lachmayer, Roland; Auer, Sören (Cham : Springer, 2022-09-04)
    The development of a novel manufacturing process chain is a com- plex scientific challenge and requires interdisciplinary and inter-institutional collaboration. Data need to be exchanged continuously ...
  • Tailored Forming of Hybrid Bevel Gears with Integrated Heat Treatment 
    Behrens, Bernd-Arno; Diefenbach, Julian; Chugreeva, Anna; Kahra, Christoph; Herbst, Sebastian; Nürnberger, Florian (Amsterdam [u.a.] : Elsevier, 2020)
    “In recent years, multi-material designs of technical components have been gaining in importance. When combining different materials in a single component, it is possible to achieve high performance and extended functionality ...
  • An X-ray Microscopy Study of the Microstructural Effects on Thermal Conductivity in Cast Aluminum-Copper Compounds 
    Fromm, Andreas Christopher; Kahra, Christoph; Selmanovic, Armin; Maier, Hans Jürgen; Klose, Christian (Basel : MDPI, 2023)
    A metallurgical joint between aluminum and copper established by compound casting provides for high thermal conductivity, which is required for lightweight cooling solutions in applications such as high-power light-emitting ...
