Student Projects (6 CP)

• Student Project IfW-AMB-01 (Bachelor); German Course

Fields of Study: Mechanical Engineering and Materials Science
Topic: Maximizing the Tensile Strength of a Compressor Blade Made of the Titanium Alloy Ti 6Al 2Sn 4Zr 2Mo

Description: The Ti 6Al 2Sn 4Zr 2Mo alloy belongs to the group of two-phase titanium alloys, in which the properties can be significantly influenced by the microstructure. This alloy is used as a compressor blade material in some aircraft engines. The objective of this project is to maximize the tensile strength of the Ti 6Al 2Sn 4Zr 2Mo alloy through heat treatment, while ensuring that the elongation at break remains at least 10% (ASTM B 348).
 

• Student Project IfW-AMB-02 / IfW-AMB-03 (Bachelor); German Course

Fields of Study: Mechanical Engineering and Materials Science
Topic: Microstructural Optimization of a Fan Blade Made of the Titanium Alloy Ti 6Al 4V

Description: The Ti 6Al 4V alloy belongs to the group of two-phase titanium alloys, in which the properties can be significantly influenced by the microstructure. This alloy is used as a fan blade material in some aircraft engines. The objective of this project is to maximize the tensile strength of the Ti 6Al 4V alloy through heat treatment. However, the elongation at break must be at least 10% (ASTM B348).
 

• Student Project IfW-LRT (Bachelor); German Course

In collaboration with aerospace engineering institutes
Fields of study: Aerospace Engineering

Specialty Lab Courses

• Specialty Lab Course IfW-FL-I "Analyse eines technischen Schadensfalles" (2 CP, German Course)

(Bachelor, Module "Technische Schadensfälle mit Labor")

• Specialty Lab Course IfW-FL-III "Kompetenzfeldlaborlabor Luft- und Raumfahrttechnik", Teilversuch Werkstoffe (0,66 CP)

Topic: Material selection for the leading edge of a passenger aircraft wing

(Bachelor, Kompetenzfeldlabor Luft- und Raumfahrttechnik)

Topics for student research projects and theses would be based on the aforementioned research on the PBF-LB/M pressure of Ti-13Nb-13Zr. A thesis would consist of both a theoretical and an experimental component. Are you interested in such a project? If so, please send me an email.
