1. 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

2. 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

4. 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

5. 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

6. Development of a Material for Manufacturing a Mold for Plastic Injection
Injection molding is a process used to manufacture high volumes of plastic containers of complex geometric shapes. Although CuBe has always been used, there are currently some alternative alloys such as the CuNiSiCr alloy that has lower manufacturing cost and similar properties. The objective of this paper is to characterize, by techniques of microscopy, the

7. A Study on Formation Process of Secondary Upsetting Defect in Electric Upsetting and Optimization of Processing Parameters Based on Multi-Field Coupling FEM
The electric upsetting process is an excellent electrically assisted preforming technique with electrical-thermal-mechanical multi-field coupling characteristic. The secondary upsetting defect in electric upsetting with inappropriate parameters combinations could result in folds in subsequent forging process. In order to analyze the formation process of the

8. Numerical Simulation of Hot Closed Die Forging of a Low Carbon Steel Coupled with Microstructure Evolution
Hot closed die forging is a regular process applied to manufacture metallic components used in supporting and fixing cable conductors in electric power transmission lines. In this forming process, the final microstructure of the workpiece depends on the control of several processing parameters. In this study, simulation of the industrial forging process of a

9. The effect of cold forming on structure and properties of 32 CDV 13 steel by radial forging process
The present study focuses on the effect of various degrees of plastic deformation generated by cold radial forging on the mechanical properties and the fracture morphology of 32 CDV 13 steel. The cold forging percentage was evaluated for 17.45, 33.30, 42.0 and 46.47 %. The microstructural analysis of the steel shows tempered martensite. The tensile strength,
