... cases are reported here. Example: Microweld Defect: Failure of a Hip Prosthesis A hip prosthesis, made of a Co-Cr-Mo-C alloy, was implanted in a patient fractured by fatigue in the stem portion ( Fig. 2.9 ). After surgical removal of the prosthesis and failure analysis, it was found that a crack...
