Projekt 11

Tailor rolling of High Strength Aluminium Alloys

Die Verwendung von Aluminium-Legierungen ist  in den letzten Jahren deutlich gestiegen und hat zu einer erheblichen Gewichtsreduktion geführt. Dieser Gewichtsreduktionstrend muss mit zusätzlichen Leichtbautechnologien beibehalten werden. Flexibel walzen (Tailor Rolled Blanks - TRB) bieten eine interessante Lösung durch eine angepasste Dickenverteilung, die eine optimierte Gewichtsverteilung ermöglicht. Diese Technologie ist jedoch derzeit auf Stähle beschränkt. Die industrielle Machbarkeit von TRB mit hochfesten Aluminiumlegierungen muss noch nachgewiesen werden. Insbesondere die Lösungsglühphase, die notwendig ist, um die endgültigen Eigenschaften zu gewährleisten, muss nachgewiesen werden.


Projekt 19

Simulation of microstructure and yield stress during natural and artificial aging of Al-Mg-Si automotive sheet

Projekt 20

Ultrasonic Particle Detector

Main objective of this project is to develop an ultrasonic detector for non-metallic inclusions in aluminum melts, which is able to verify melt quality and is able to operate under industrial conditions. Research focus is to develop a measurement system that ensures a high reproducibility and continuity regarding the measurement results. Furthermore, the measurement system is supposed to operate without expert knowledge.

Projekt 22

UniCorn - Understanding the Intergranular Corrosion of 6000 Aluminium Alloys 

The present project will undertake a methodical investigation on the mechanism of intergranular corrosion in 6000 alloys. The influence of the Mg/Si ratio, the copper content, and the heat treatment on phase precipitation and its effect on intergranular corrosion will be analyzed.

Projekt 24

Cast Part Feasibility Assessment Method

In-service performance of cast parts not only depends on part design, but also on manufacturing effects like part orientation in mold, gating & feeder system (size, location) and process parameters (filling rates, melt & die temperatures). Casting process restrictions and requirements are of equal importance as attribute requirements (strength, durability, NVH, crash).

Conventional component optimization relies on expert skills and expert guided analysis loops. MDO tools as well as design engineers require fully automated tools & expert systems to evaluate the feasibility and quality of cast parts upfront, quantitatively and efficiently.

The objective is to develop an automatic tool set to run casting simulations, to quantify existing casting process know-how, to make it available for automatic evaluation schemes and to provide validation example parts.
