3. Austenitic Grain Size Prediction in Hot Forging of a 20MnCr5 Steel by Numerical Simulation Using the JMAK Model for Industrial Applications
Yield strength and toughness in steels are directly associated with hot forging processes, especially by controlling austenitic grain size and cooling conditions. The phenomenological JMAK model in macroscale has been applied in different material classes to predict grain size after hot forming. However, on an industrial application, there is still a lack of

4. Variaciones Greenberg: apogeo y debacle de un crítico de arte
Abstract: Starting from the classic text Avant-garde and kitsch, we propose to analyze the work of the North American critic Clement Greenberg. After the US state intervention in the arts between 1935 and 1943 (the WTA), Clement Greenberg emerged as one of the main critics who sought to unify the “high art” of that country. The critic attempted to justif

5. Effect of α/β Forging on Microstructure and Texture Inhomogeneity in a Ti-1023 Forged Disk
The microstructure and texture distribution of a Ti-1023 forged disk were investigated by scanning electron microscopy and synchrotron-based high-energy X-ray diffraction. The finite element method was used to simulate temperature and strain distribution in order to investigate the relationship of the α/β forging process with microstructure and texture dis

6. Inmigrantes francófonos en los orígenes de la comunicación visual en la prensa peiódica argentina (1827-1870)
ABSTRACT This paper presents a periodization of Francophone immigration with an impact on the visual activity of the press in Argentina, in three main moments after its first emergence in the 1820s. The periodization shows that its first two moments coincide with the First and second stage of the development of visual arts for the periodic press in the count

7. Trabajo Social y gestión. Oportunidad conflictuada
Resumo Este artigo questiona a construção subjetiva que emerge na relação conflituosa entre o Serviço Social e a gestão de políticas sociais. Para tal, é realizada uma análise do discurso segundo a perspectiva dos autores Potter e Wetherell, tendo como referências entrevistas vinculadas a um projeto de pesquisa disciplinar desenvolvido entre os ano

8. Tri-modal Microstructure in Different Loading Zones Under TA15 Ti-alloy Isothermal Local Conventional Forging and Given Subsequent Heat Treatment
For TA15 Ti-alloy large-scale component, isothermal local conventional forging (ILCF) combined with subsequent heat treatment provides a feasible approach to obtain a tri-modal microstructure with attractive comprehensive performance. However the tri-modal microstructure characteristics and evolution laws in the first and second loading zones are lack of und

9. REFRAMING IDENTITIES IN THE MOVE: A TALE OF EMPOWERMENT, AGENCY AND AUTONOMY
RESUMO Movimentos transnacionais alçados pela globalização a um nível de normalidade, para não de dizer de absoluta necessidade, reconstruíram o mundo e suas práticas sociais. Como prática social, as dimensões da língua adquirem também uma nova importância na forma como as pessoas usam e consomem línguas funcionando, assim, como agentes no exerc

10. Influence of Forging Pressure on Microstructural and Mechanical Properties Development in Linear Friction Welded Al-Cu Dissimilar Joint
Abstract Dissimilar AA5083 and C101 pure copper linear friction welds were prepared using different forging pressures (60 MPa, 80 MPa, and 110 MPa) to investigate the influence of the forging pressure on the microstructural and mechanical properties development using optical microscopy (OM), scanning electron microscopy (SEM), hardness measurements, and ten

11. Estudio de la formabilidad en caliente de aleaciones de titanio a través del ensayo de torsión y su aplicación a la optimización de procesos de forja y extrusión
ABSTRACT In the development of hot metal forming, the metallic products must comply with the requirements imposed by current standards. In some cases, the required microstructure can only be obtained through thermomechanical processing. With titanium and its alloys, small ranges of good workability are an additional difficulty. In this work the hot-workabili

12. Thermomechanical Modelling of FSW Process Using a Cylindrical Tool in an Aluminum Alloy Alclad AA 2024-T3
The Friction Stir Welding Process (FSW/P) is an innovative technique to join metals using the plasticity, not occurring the melting. It was initially applied in aluminum alloys, but recently it has been extended to other materials, for example, copper, steel alloys, polimers and others. In this work it is analyzed the thermo mechanical modelling of the energ
