Modelling grain boundary migration during geometric dynamic recrystallization
(TAYLOR & FRANCIS LTD, 2008)
High-angle grain boundary migration is predicted during geometric dynamic recrystallization (GDRX) by two types of mathematical models. Both models consider the driving pressure due to curvature and a sinusoidal driving ...
Quartz recrystallization regimes, c-axis texture transitions and fluid inclusion reequilibration in a prograde greenschist to amphibolite facies mylonite zone (Ribeira Shear Zone, SE Brazil)
(ELSEVIER SCIENCE BV, 2010)
The crystal-plastic behavior of quartz mylonites from the Ribeira Shear Zone (SE Brazil), a major strike-slip structure that was active during a prograde metamorphic phase related to the Neoproterozoic Brasiliano-Pan African ...
Numerical modeling of flow stress and grain evolution of an Mg AZ31B alloy based on hot compression tests
(2020-01-01)
Magnesium alloys offer a wide range of applications in modern lightweight structures, although the correct forming parameters need to be found to reach a good combination of fine microstructure and the required mechanical ...
Interaction between recrystallization and strain-induced precipitation in a high Nb- and N-bearing austenitic stainless steel: influence of the interpass time
(Elsevier B.V., 2015-06-18)
In this work, we studied the influence of the interpass time (20 and 5 s) on the interaction between recrystallization and strain-induced precipitation occurring during multiple passes'deformations under continuous cooling ...
Continuous dynamic recrystallization in a Zn–Cu–Ti sheet subjected to bilinear tensile strain
(Elsevier Science SA, 2020-07)
Research on zinc sheet formability, relevant for its technological applications, requires deeper understanding of the microstructural features that govern the plastic response of the material. In this work, a microstructural ...
Microstructural Evolution During Friction Stir Welding Of Mild Steel And Ni-based Alloy 625
(SpringerNew York, 2017)
Modelagem matemática de curvas tensão-deformação
(Universidade Federal de Minas GeraisUFMG, 2008-12-12)
Ti or other elements as, for instance, Nb or V, when added as microalloying elements, exert a retarding effect on the kinetics of static recrystallization, leading to pancaking of austenite when deformed at temperatures ...
Hot deformation behavior of a ni‐based superalloy with suppressed precipitation
(Multidisciplinary Digital Publishing Institute, 2021-04-08)
Abstract:Inconel ® 718 is a well-known nickel-based super-alloy used for high-temperature applicationsafter thermomechanical processes followed by heat treatments. This work describes theevolution of the microstructure and ...
