Determination of Material Properties of Ti6Al4V for Numerical Simulation of the Machining Process
This Master's thesis focuses on the experimental determination of material properties for Ti6Al4V, essential for the numerical simulation of machining processes. The work involves preparing various samples, conducting flow curve tests, damage behavior analyses, and anisotropy assessments. Additionally, EBSD analysis, hardness measurements, and potentially chemical analyses will be performed. The results will be used to validate machining simulations using SPH/FEM, comparing process forces and chip formation.
**Motivation:**
Despite over a century of intensive research, machining of materials remains a significant challenge. Numerical methods are increasingly used to optimize the machining process and enhance process understanding. This thesis aims to experimentally determine the mechanical properties required for these simulations. Various samples will be prepared from existing materials for testing.
**Tasks:**
- Sample preparation
- Conducting material tests to determine flow curves, damage behavior, and anisotropy
- EBSD analysis and evaluation (texture, grain size, phase composition) before and after material tests
- Hardness measurements and potentially chemical analysis
- Simulating a machining test conducted during the thesis using SPH/FEM, comparing process forces and chip formation.
**What We Offer:**
- An exciting Master's thesis
- Introduction to experimental research, measurement technology, modern microscopy, and evaluation methods, and material investigations
- Opportunity for FEM simulation to validate tests
- A thesis tailored to personal interests
- Expansion of knowledge and skills in industrially relevant research
**Your Profile:**
- Master's student in Mechanical Engineering / Materials Science
- Interest/Fascination in experimental work and its evaluation
- Independence, accuracy, and conscientiousness
- Interest in programming/ CAD design / Simulation
