The aim of this thesis is to find and evaluate the actual oxygen content in a Ti64 surface after HIP/heat treatment in different oxygen containing processing atmospheres, ranging from a detrimental level heating a HIPed sample in air to a possible optimum level HIPing with Purus(R) strategy. This oxygen can be in the form of surface oxides or as interstitial oxygen stabilizing the alpha phase forming a brittle surface layer called “alpha case” that needs to be removed before use in critical applications. The work will preferably be carried out at an institution having access to SEM/EDS equipment and heat treatment furnaces. HIP trials to be done at Quintus Application Center. Material samples to be decided and cooperation with AM printing work preferred
Suggested research questions for this Thesis.
- How is the correlation between oxygen content in processing atmosphere, oxygen compounds formed and depth below surface?
- How does the above correlate to inspection criteria for alpha case in medical implants
Master of Science programme with specialisation in materials science, mechanical engineering, additive manufacturing or metallurgy.
