Effect of the oxygen content on mechanical properties of titanium samples produced by an ultrafast sintering process (already assigned to a student)

During this semester project, the student will have the opportunity to study titanium samples produced by a new ultrafast sintering process, with different levels of commercial purity: Grade 2, Grade 3, Grade 4. The main difference between the three grades is the level of oxygen.
The goal of this semester project is to determine the influence of the oxygen content on the mechanical properties of titanium thus produced. The properties studied are:

  • Young modulus: This property will be studied using an innovating method based on vibrating properties of the samples
  • Hardness: It seems that hardness should increase with the oxygen content.
  • Sample microstructure: This property may evolve with the oxygen content.
  • Sample density

If there is enough time, tensile tests could also be implemented to determine both ductile behavior and maximal tensile stress of the samples.
This project will also be the opportunity for the student to work (once or twice) with EPoS society, which owns and developed the sintering process. This one is called Electro-Sinter Forging and combines a mechanical pulse and an electronical pulse, which ensures a sintering close to full density, and ultrafast: the sample is obtained in a few seconds.
