ASTM F138 Steel Metallurgical Characterization and CTOD Analysis Applicable to Orthopedic Implants
AbstractThe purpose of this paper is to verify the proceedings of the fracture toughness test CTOD applied to austenitic stainless steel F138, commonly used for orthopedic implants. A metallurgical characterization of sample materials was performed in which chemical composition analysis, micrographs, micro Vickers hardness tests, inclusion analysis, and scanning electron microscopy were also evaluated. In order to illustrate the technique, some rejected samples by the quality control from different suppliers were obtained and tested. This study was based on procedures governed by standards [1,2] which regulate the performance of CTOD toughness tests, with the purpose of evaluating the mechanical resistance and useful life of prosthetics. The standard  governing the basic properties of materials accepted for prosthetic production has also been studied.
