Several microscopic techniques were adopted to reveal the distribution and morphology of DIM in the volume of fatigued steels. Results of microstructure investigations are confronted with the ferritescope measurements taken at different locations of fatigued specimens. Some factors which may impact the DIM formation in fatigued SLMed 316L steel are discussed. 10th International Conference on Materials Structure and Micromechanics of Fracture Formation of deformation induced martensite in fatigued 316L steels manufactured by selective laser melting (SLM) Jiří Man a, *, Bastian Blinn b , Ivo Šulák a , Ivo Kuběna a , Marek Smaga b , Zdeněk Chlup a , Tomáš Kruml a , Tilmann Beck b , Jaroslav Polák a a Institute of Physics of Materials ASCR, Žižkova 22, 616 00 Brno, Czech Republic b Institute of Materials Science and Engineering (WKK), TU Kaiserslautern, Gottlieb-Daimler- Straße 44, 67663 Kaiserslautern, Germany Keywords: Selective laser melting (SLM); 316L stainless steel; fatigue; deformation induced martensite; cellular dislocation substructure Keywords: Selective laser melting (SLM); 316L stainless steel; fatigue; deformation induced martensite; cellular dislocation substructure 1.
