1. Continuous Scanning Technique with Barkhausen Magnetic Noise for Carbon Steel Sheets
This work studies the application of a Non-Destructive Inspection Technique (NDIT), based on the Magnetic Barkhausen Noise (MBN), for the detection of non-homogeneous regions in carbon steel plates. It presents the advances in the development of a variant of a new non-destructive magnetic test technique, called Continuous Scanning Magnetic Barkhausen Noise (

2. Microstructure and Mechanical Properties of AA6061/AZ31B/AA6061 Composite Plates Fabricated by Vertical Explosive Welding and Subsequent Hot Rolling
In this study, three-ply Al/Mg/Al composite plates were successfully achieved by vertical explosive welding (EXW) method. After EXW, the sound joints were obtained. Then thin three-ply Al/Mg/Al EXWed composite plates with the thickness of 1.78 mm were achieved by hot rolling. The influence of annealing on the interface microstructures and mechanical properti

3. Measurement of Residual Stresses in Welded Joints by DCP Method
Residual stresses on welded joints have been studied by several methods. In this present work, residual stresses was measured by a novel methodology under development named Displacement of Coordinated Points (DCP). To evaluate anisotropy effects in steel plates, two directions of the weld bead were considered: Welding was performed in both parallel and trans

4. Polystyrene and cornstarch anti-corrosive coatings on steel
Abstract This work aims to evaluate the performance of anticorrosive thermoplastic coatings in cold rolled steel sheets. Two types of thermoplastic coatings were studied: polystyrene (PS) and cornstarch. These types of coatings are applied for protection against corrosion during transport and storage of steel plates after cold rolling until delivery to stam

5. Behavior and design of built-up compressed steel members composed of concentric hot rolled circular hollow sections
Abstract This research presents a study of the behavior of built-up compressed steel members composed of concentric hot rolled circular hollow sections. The use of these members is an innovative solution of practical interest for situations in which a single member does not reach the required compressive strength. Some technically and economically viable de

6. The Effect of Casting Speed and the Fraction of Al5%Ti1%B Inoculant on the Microstructure and Mechanical Properties of the AA5052 Aluminum Alloy Produced by the Direct Chill Process
This study aimed to assess the effect of casting speed and the addition of Al5%Ti1%B inoculant in the casted AA5052 aluminum alloy plate manufactured by the Direct Chill process. The focus of this work was to decrease the rejection index of rolled products due to the occurrence of superficial flaws on plates. These defects impact directly on the production c

7. Acoustic Birefringence and Poisson's Ratio Determined by Ultrasound: Tools to Follow-Up Deformation by Cold Rolling and Recrystallization
Poisson's ratio and birefringence, both measured by ultrasound, are used to follow the evolution of the anisotropy in ASTM A-36 steel plates cold-rolled between 5 and 50% deformation, and then subjected to recrystallization at 900 and 1000 ºC. Times of flight of longitudinal and shear waves along the thickness of the plates were measured. As orthotropy incr

8. Structural analyses of reinforced tubular T-joints
Abstract The use of rolled hollow sections has been substantially boosted mainly due to the advantages associated with structural behavior and aesthetics, leading to an intense use in Europe, Southeast Asia, North America, Australia, and now, in Brazil due to the wider supply of these profiles. Therefore, it is important to investigate the structural behavio

9. Estudo comparativo da estampabilidade da liga de aluminio AA1050 partindo de placas obtidas por vazamento direto e bobinas obtidas por vazamento contínuo. / Comparative study of the deep drawing alloy AA1050 from plates obtained by direct casting and coils obtained by continuos casting.
Stampability of aluminum alloys is a subject of interest to several industrial sectors because they are largely used in the fabrication of several parts and components. The choice is based upon the stampability and the relative manufacturing capability in relation to other aluminum alloys that contain larger amounts of alloying elements and, consequently, hi

10. Model to characterize susceptibility to distortions by welding in aluminum plates / Proposta de modelo para caracterizar susceptibilidade a distorção devido a soldagem em chapas de aluminio
The industry interest on having a better control in the distortions provoked by welding of aluminum plates, caused by the crescent demand of this material, motivated the development of this work. In this work, it is studied the deformation caused by TIG welding in aluminum plates, alloy Al 5052, in function of the cold working degree (tempers) on the plates

11. Avaliação do amaciamento em aço inoxidável ferrítico por ensaios de torção a quente
The softening behavior changes that occur during hot deformation of ABNT 430 ferritic stainless steels were analyzed by hot rolling simulation using torsion tests aiming at achieving better microstructure for drawing process. Torsion specimens were machined from hot rolled plates 28mm in thickness after roughing mill. Interrupted deformation torsion tests we

12. Análise numérica não-linear da flambagem local de perfis de aço estrutural submetidos à compressão uniaxial
Local buckling of plates normally presents large displacements in the normal direction of the medium plane of the plate due to small loading changes, with the axis of the bar remaining straight. This is a typical phenomenon of axially compressed steel columns, composed either with welded or hot- rolled structural shapes. When the plate buckles locally, there
