Correlation between microstructure and mechanical properties before and after reversion of metastable austenitic stainless steels
Fargas Ribas, Gemma; Zapata, Ana; Roa Rovira, Joan Josep; Sapezanskaia, Ina; Mateo García, Antonio Manuel (2015)
Article
Accés obertReversion treatments are a way to improve the mechanical response of metastable austenitic stainless steels by means of grain refinement. To effectively apply those treatments, the steel must be previously deformed to ... -
Deformation mechanisms induced by nanoindentation tests on a metastable austenitic stainless steel: a FIB/SIM investigation
Sapezanskaia, Ina; Roa Rovira, Joan Josep; Fargas Ribas, Gemma; Turón Viñas, Miquel; Trifonov, T.; Kouitat Njiwa, R.; Redjaïmia, A.; Mateo García, Antonio Manuel (2017-09)
Article
Accés obertMetastable austenitic stainless steels are materials that can undergo austenite to martensite phase transformation when subjected to deformation and thus they represent a multiphase material with interesting mechanical ... -
Deformation mechanisms of metastable stainless steels accessed locally by monotonic and cyclic nanoindentation
Sapezanskaia, Ina (Universitat Politècnica de Catalunya, 2016-07-21)
Tesi
Accés obert
Realitzat a/amb: Université de LorraineMetastable austenitic stainless steels feature an abundance of different deformation mechanisms, which contribute to the distinguished mechanical properties of these alloys. However, these properties are known to depend ... -
Dynamic deformation of metastable austenitic stainless steels at the nanometric length scale
Roa Rovira, Joan Josep; Sapezanskaia, Ina; Fargas Ribas, Gemma; Kouiat, R.; Redjaïmia, Abdelkrim; Mateo García, Antonio Manuel (2018-09-17)
Article
Accés obertCyclic indentation was used to evaluate the dynamic deformation on metastable steels, particularly in an austenitic stainless steel, AISI 301LN. In this work, cyclic nanoindentation experiments were carried out and the ... -
Influence of testing mode on the fatigue behavior of <111> austenitic grain at the nanometric length scale for TRIP steels
Roa Rovira, Joan Josep; Sapezanskaia, Ina; Fargas Ribas, Gemma; Kouitat, R.; Redjaïmia, A.; Mateo García, Antonio Manuel (2018-01-24)
Article
Accés obertMetastable austenitic stainless steels, and in particular the TRansformation Induced Plasticity steels, rely on a phase transformation from a ductile austenite to a slightly harder martensite. These materials under fatigue ... -
Reversible phase transformation in polycrystalline TRIP steels induced by cyclic indentation performed at the nanometric length scale
Roa Rovira, Joan Josep; Sapezanskaia, Ina; Fargas Ribas, Gemma; Kouitat, R.; Redjaïmia, A.; Mateo García, Antonio Manuel (2018-09-17)
Article
Accés obertMetastable austenitic stainless steels are an interesting group of materials, which exhibit the Transformation Induced Plasticity effect. In this regard, phase transformation from austenite to martensite enhances the work ... -
Transmission of plasticity through grain boundaries in a metastable austenitic stainless steel
Mateo García, Antonio Manuel; Sapezanskaia, Ina; Roa Rovira, Joan Josep; Fargas Ribas, Gemma; Redjaïmia, Abdelkrim (Multidisciplinary Digital Publishing Institute (MDPI), 2019-02-01)
Article
Accés obertAustenitic metastable stainless steels have outstanding mechanical properties. Their mechanical behavior comes from the combination of different deformation mechanisms, including phase transformation. The present work aims ...
