Analysis of Phase Transformation of Austenitic 316L Implant Steel during Compression

Abstract:

The present work concerns development of porous materials for medicine applications. The implant alloys should be paramagnetic because of the danger of reaction with blood cells. However, the strain-induced martensitic transformation may take place due to high strain during implants use. The porous samples made of the 316 stainless steel by the powder metallurgy method were investigated. The results of magnetic studies as well as X-Ray diffraction analysis of sintered specimens after compression tests are presented. The changes in magnetic properties of sintered steel were observed as result of mechanical testing, particularly in case of compression with high strain. Whereas, the X-Ray diffraction did not confirm the phase transformation of austenitic steel.
