Dating recurrent shear zone activity and the transition from ductile to brittle deformation: white mica geochronology applied to the neoproterozoic Don Feliciano Belt in South Brazil
(Pergamon-Elsevier Science Ltd, 2020-09-22)
Argon geochronology of white mica has a good potential of recording recurrent dynamic recrystallization in shear zones in the transition from ductile to brittle deformation, as temperature ranges for mineral crystallization ...
Synkinematic interplay between felsic dykes and host rock mylonitization: how magmatism assists the formation of ductile narrow shear zones in the Sierra Chica de Córdoba, Argentina
(Pergamon-Elsevier Science Ltd, 2021-03-09)
This study provides new insights about mechanisms of synkinematic interplay between dyking emplacement and ductile narrow shear zones formation in the Sierra Chica de Córdoba. A detailed analysis of structural, microstructural, ...

Estructura, cinemática y condiciones de la deformación de la faja de cizalla Pinchas: evidencias de la fase tectónica Oclóyica en la sierra de VelascoStructure, kinematic and deformation conditions of the Pinchas shear zone: evidences of the Ocloyic tectonic phase in the Sierra de Velasco
(Asociación Geológica Argentina, 2019-12)
Los estudios petro-estructurales desarrollados sobre el basamento metamórfico-ígneo del noreste de la sierra de Velasco permitierondefinir y caracterizar una nueva faja de deformación dúctil denominada faja de cizalla ...
Abrasion resistance and toughness of a ductile iron produced by two molding processes with a short austempering
(Elsevier, 2019-06)
Austempered ductile irons (ADI) have been extensively used in applications that require a high wear resistance. To further improve it, this work analyzes the effects of both two molding conditions and a short austempering ...
Mechanical and tribological behavior of Ti/TiN and TiAl/TiAlN coated austempered ductile iron
(Elsevier Science Sa, 2018-02-01)
Bilayer Ti/TiN and TiAl/TiAlN coatings were deposited onto austempered ductile iron (ADI) substrates by cathodic arc deposition in an industrial device. Structure and mechanical properties of the coated samples were ...
Neogene Tiporco Volcanic Complex, San Luis, Argentina: An explosive event in a regional transpressive - local transtensive setting in the pampean flat slab
(Pergamon-Elsevier Science Ltd, 2017-07)
The Neogene Tiporco Volcanic Complex (TVC) is located in the Sierras Pampeanas of San Luis, Argentina, at the southeast of the Pampean flat-slab segment. Based on the comprehensive study of lithofacies and structures, the ...
Damage evolution during tensile test of austempered ductile iron partially austenized
(Wiley, 2020-02)
The goal of this work is to analyze the damage evolution at microstructural scale of an austempered ductile iron partially austenized during tensile loading. The analysis is carried out by means of step-by-step tensile ...
Estimation of the fracture toughness threshold of a ferritic steel at the lower ductile to brittle transition region
(Universidade Federal de São Carlos, 2016-09)
The ADN420 ferritic steel (A615 steel Grade 60 [420]), used as reinforcing bars (rebar) in concrete, shows the so called ductile to brittle transition. Room temperature is located on the lower third region of the transition ...
