Background
>> replacement of human joints (implants) becomes more important (demographic change)
>> materials for medical implants offer several challenges and potential for improvements

Objective
>> to offer small-scale solutions for improvements by using in-situ methods to investigate and analyze materials and the related mechanisms for medical implants

Methods
>> mechanical and thermal treatments
>> SEM-EDS (energy dispersive X-ray spectroscopy) / EBSD (electron backscatter diffraction) in-situ methods

Results
>> clarification of phase transformation mechanisms of CoCrMo alloys (requirements, activation, process, consequences)
>> phase-related (microstructure) properties of CoCrMo alloys in various conditions

Conclusions
>> materials science-based recommendations for possible improvements for medical implants with regard to possible changes of chemical composition and/or pre-treatments before implantation

Orignality
>> research at the intersection between mechanical engineering and medicine
>> unique combination of methods (in-situ SEM) and materials (biomedical implants) offers new informative and helpful insights into mechanisms in materials for medical implants
