1. Microstructural characterization of the A356 alloy in different processing routes used in the thixoforming process
ABSTRACT This work aims to evaluate different routes of raw material production to be used in thixoforming process. The semisolid materials exhibit particular structural characteristics, such the characteristic non dendritic structure. The studies for the production of near-net-shape parts have progressed together with the studies of material weight reductio

2. Metallurgical Characterization of API X65 Steel Joint Welded by MIG Welding Process with Axial Magnetic Field
In this work, API X-65 pipeline steel non-conventionally heat treated, to enhance its mechanical resistance, was welded using the Metal Inert Gas (MIG) process with and without the application of low intensity axial magnetic fields (6 mT). Microstructural and mechanical characterization of the welds revealed that the use of the magnetic field during welding

3. Numerical model of electromagnetic stirring for continuos casting billets
Thispaperintroducesanumericalmodelofanelectromagnetic rotary stirrer based on the finite-element model.Such stirrers are used to improve the quality of continuously cast steel, particularly billets and blooms. The method determines the magnetic flux density profile and compares it to experimental measurements. In addition, it calculates the Lorentz force fie

4. Trinca de solidificação off-corner no lingotamento contínuo de Tarugos
Internal cracks are a major quality problem in the continuous casting of billets. At Belgos plant, located in João Monlevade, off-corner crack is the most common kind of internal crack in steel billets. This type of crack occurs more frequently in medium carbon steels (carbon content between 0.25 and 0.45%). The focus of the present investigation is the ide

5. Projeto e construção de equipamento eletromagnetico para a produção de materia-prima para tixoconformação de ligas metalicas / Design and development of an electromagnectic equipment for the production of raw material for thixoforming of metal alIoy
This work relates the design and development of an equipment capable of modifying the morphology of primary phase during solidification of metal alloys, differentiating such structures ftom those dendritic obtained in conventional solidification. In this process turbulence is imposed to the liquid metal by means of a external force with the purpose of modify
