Efecto del procesado del material sobre la velocidad de las ondas y sus consecuencias en la inspección por ultrasonidos
Llumà Fuentes, Jordi; Roca Vallmajor, Antoni; Jorba Peiró, Jordi; Llorca Isern, Núria; Solà Saracibar, Joan (Editorial de la Universitat Politècnica de València (UPV), 2011)
Conference report
Open AccessLa medida de la velocidad de propagación de las ondas ultrasónicas es una técnica precisa y bien establecida. A menudo esta fiabilidad la hace útil para la inspección asumiendo que estas velocidades son constantes para ... -
Effect of severe plastic deformation on microstructure and properties of duplex stainless steel
Gennari, C.; Pezzato, L.; Llorca Isern, Núria; Lopez, I.; Cabrera Marrero, José M.; Chand, M.; Roca, A.; Calliari, Irene (2017-09)
Article
Restricted access - publisher's policyThe excellent performance of dduplex and super duplex stainless steels due to their high corrosion resistance and high mechanical strength is directly related to their austeno-ferritic microstructure. However, these steels ... -
Effect of the nanostructuring by high-pressure torsion process on the secondary phase precipitation in UNS S32750 Superduplex stainless steel
Biserova Tahchieva, Alisiya; Llorca Isern, Núria; Cabrera Marrero, José M. (2022-01)
Article
Restricted access - publisher's policyIn this work, the precipitation and the morphology of secondary phases after severe plastic deformation (SPD) processing followed by an isothermal treatment was investigated. High-pressure torsion (HPT) was the SPD process ... -
Enhancing ductility of ECAP processed metals
Llorca Isern, Núria; Grosdidier, Thierry; Cabrera Marrero, José M. (2010)
Article
Restricted access - publisher's policyMechanical properties such as hardness, mechanical strength or fatigue resistance are by far the most successful material behaviour improved by the ECAP processed. However, the lack of ductility is the most critical negative ... -
Equal channel angular pressing of Cu-Al bimetallic rods
Llorca Isern, Núria; Escobar, Ana Maria; Roca, Antoni; Cabrera Marrero, José M. (2012)
Article
Restricted access - publisher's policyCoextrusion and corolling are the major processes to produce bimetallic rods, tubes and wires, the objective being to perform clad metals, bimetallic joints or seals. The aim of the present work is to produce bimetallic ... -
Influence of severe plastic deformation in phase transformation of superduplex stainless steels
Llorca Isern, Núria; Biserova Tahchieva, Alisiya; López Jiménez, Isabel; Calliari, Irene; Cabrera Marrero, José M.; Roca, Antoni (Springer, 2019-02-01)
Article
Open AccessDuplex and superduplex stainless steels are characterised by high corrosion resistance and high mechanical strength. However, these steels can suffer formation of secondary brittle phases when they reach temperatures between ... -
