Numerical Investigation of the Oxide Scale Deformation Behaviour with Consideration of Carbon Content during Hot Forging

B.-A. Behrens, R. Kawalla, B. Awiszus, A. Bouguecha, more

Procedia Engineering > 2017 > 207 > C > 526-531

Due to increasing product requirements the numerical simulation has become a powerful tool for the effective and efficient design of individual process steps as well as entire process chains. In order to model hot forging processes with finite element based numerical methods realistic models are required which consider the detailed mathematical description of the material behaviour during the forging...

Enhancing the applicability of Al-Mg compounds by using forming and welding technologies

W Förster, S. Habisch, C. Binotsch, B. Awiszus, more

Procedia Engineering > 2017 > 207 > C > 1659-1664

The role of oxide layers in the formation of a sufficient bonding between aluminum (Al) and magnesium (Mg) as a compound is essential, due to their impediment of the diffusion process. For this investigation into the formability and weldability of such compounds, specimens with an Mg core and an Al cladding were prepared by chemically removing the oxide layers. The specimens were joined mechanically...

Towards intelligent materials testing with reduced experimental effort for hot forming

M. Bambach, M. Imran, J. Buhl, S. Härtel, more

Computer Methods in Materials Science > 2017 > Vol. 17, No. 1 > 44--50

Hot forming processes are typically used to deform metals to the desired shape at lower forming forces and to control the microstructure. During hot deformation, the microstructure evolves by dynamic recrystallization after certain critical conditions are reached. The final recrystallized grain size controls the post-hot forming mechanical properties of metals and components. To predict the evolution...

Multidimensional Analysis of Process Chains Regarding the Resource-efficient Manufacturing of Hybrid Structures

C. Fanghänel, A. Rautenstrauch, C. Symmank, J. Katzenberger, more

Procedia CIRP > 2015 > 26 > Complete > 595-600

One of the leading topics in the automotive industry as well as in the aircraft and aerospace sector is the use of lightweight structures for weight reduction. For this purpose, hybrid materials, e.g. metal-plastic structures, are of essential importance. Despite the high technological challenge, the manufacturing techniques still provide versatile development potential. Especially the integration...

Separation of Corrosion-affecting Parameters of Formed Products – A New Strategy Using X-ray Diffraction and Corrosion Tests Under in-situ Tensile Load

T. Mehner, A. Bauer, D. Nickel, C. Binotsch, more

Materials Today: Proceedings > 2015 > 2 > Supplement 1 > S141-S148

The effects of several parameters on corrosion behavior cannot be separated by currently available methods. A new approach is described that combines X-ray diffraction, corrosion and tensile tests, which allows for the separation of the corrosion-affecting influences like residual stresses. It is demonstrated that the studied DC04 sheets become less noble with increasing tensile stress. Using the...

Interface Engineering of Aluminum-magnesium Compounds

W. Förster, C. Binotsch, B. Awiszus, D. Dietrich, more

Materials Today: Proceedings > 2015 > 2 > Supplement 1 > S3-S8

To combine the low density of magnesium with the corrosion resistance of aluminum in one component, a joint processing has gained scientific interest. It has been shown, that Al-Mg compounds and components with the material combination AlMgSi1/MgAl3Zn can be produced successfully by hydrostatic co-extrusion and forging. The interface region consists of the two phases β (Al ₃ Mg ₂ )...

Corrosion Protection of Al/Mg Compounds by Simultaneous Plasma Electrolytic Oxidation

M. Sieber, R. Morgenstern, D. Nickel, I. Scharf, more

Materials Today: Proceedings > 2015 > 2 > Supplement 1 > S149-S155

The application of Al/Mg compound materials for lightweight structures is limited by their corrosion susceptibility. The primary corrosion attack takes place at the Mg component. This may partly be caused by galvanic corrosion and partly by the insufficient formation of a natural passive layer on magnesium. Therefore, oxide coatings were produced on the co-extruded Al/Mg compounds by simultaneous...

Materialeigenschaften und Formänderungsvermögen von stranggepressten Al‐Mg‐Verbunden in Abhängigkeit der Temperatur

A. Feuerhack, C. Binotsch, B. Awiszus, A. Wolff, more

Materialwissenschaft und Werkstofftechnik > 43 > 7 > 601 - 608

Die ersten Untersuchungen der hydrostatisch stranggepressten Al‐Mg Verbunde als Halbzeuge für Folgeprozesse wie Gesenkschmieden verdeutlichen das große Potenzial hybrider Werkstoffverbunde. Die experimentellen Analysen ergaben, dass die Grenzschicht ein hohes Umformvermögen aufweist. Mit verschiedenen Gesenkschmiedeoperationen konnten Umformgrade von 1,50 erreicht werden, ohne dass eine Schädigung...

Bruchmechanische Eigenschaften von Al/Mg‐Verbunden und deren Fließverhalten im Herstellungsprozess

T. Lehmann, M. Stockmann, K. Kittner, C. Binotsch, more

Materialwissenschaft und Werkstofftechnik > 42 > 7 > 612 - 623

Die Prozessanalyse des Verbundstrangpressens und mechanische Eigenschaften des Interfaces zwischen beiden Verbundpartnern werden im Folgenden dargelegt. In der Prozessanalyse wird das Fließverhalten des Mantelmaterials (Aluminium) und des Kernmaterials (Magnesium) untersucht. Dies war notwendig, um im Prozess entstandene Risse im Interface auszuschließen. Um den Prozess entsprechend der entstehenden...

Numerical simulation of non-circular spinning: a rotationally non-symmetric spinning process

B. Awiszus, S. Härtel

Production Engineering > 2011 > 5 > 6 > 605-612

This paper describes the peculiarities encountered in the numerical modeling of non-circular spinning processes using motion-controlled roller tools and applying the Finite Element Method (FEM). This process is suitable for producing non-circular, hollow components in small to medium-sized production lots. Numerical simulation can be used to optimize the process. Therefore, it is necessary to make...
