Role of the flat-designed surface in improving the cyclic fatigue resistance of endodontic NiTi rotary instruments [PDF]
, 2019 The aim of this study was to investigate the role of the flat-designed surface in improving the resistance to cyclic fatigue by comparing heat-treated F-One (Fanta Dental, Shanghai, China) nickel-titanium (NiTi) rotary instruments and similar prototypes,

Understanding the interaction between a steel microstructure and hydrogen [PDF]
, 2018 The present work provides an overview of the work on the interaction between hydrogen (H) and the steel’s microstructure. Different techniques are used to evaluate the H-induced damage phenomena. The impact of H charging on multiphase high-strength

In situ heat treatment in selective laser melted martensitic AISI 420 stainless steels
Materials & Design, 2015 The article explores an evolution of a microstructure in AISI 420 martensitic stainless steel during selective laser melting. Several upper layers had hardness of 750 HV and contained 21 ± 12 vol.% austenite phase. The final bulk microstructure consisted

Influence of testing mode on the fatigue behavior of <111> austenitic grain at the nanometric length scale for TRIP steels [PDF]
, 2018 Metastable 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.

Microstructure evolution in a 316L stainless steel subjected to multidirectional forging and unidirectional bar rolling [PDF]
, 2014 The formation of ultrafine-grained structures was studied in a 316L stainless steel during severe plastic deformation. The steel samples were processed up to a total amount of strain of 4 at ambient temperature using two different methods, i.e ...
