“…Para liga AA 5052, a ¼ de espessura, as componentes cobre ( 112 A presença de uma forte componente cubo (001)[01̅ 0] afeta a evolução da textura de deformação durante a laminação. Estudos reportam que, a fração volumétrica da orientação cubo {100}<001> diminui com o aumento da redução da espessura, o que contribui para uma distribuição de orientações mais aleatória e, consequentemente, influência nas propriedades mecânicas, e que a intensidade da orientação cubo é maior na liga produzida por fundição direta (DC) do que a produzida via fundição contínua de chapas (TRC) [26,27].…”

RESUMO No setor automotivo as ligas de alumínio têm se destacado por sua atraente combinação entre resistência/peso, entre outras características. As ligas da série 5XXX tem seu ganho de resistência mecânica através de processos de deformação a frio, e as propriedades mecânicas das ligas de alumínio estão diretamente relacionadas à sua composição e ao processo de fabricação utilizado em sua manufatura. Um dos requisitos para otimizar as operações de conformação mecânica é o controle da microestrutura e textura. Neste trabalho, as ligas AA 5052 e AA 5050C, produzidas por Fundição Direta (Direct Chill – DC), e Fundição Contínua de Chapas (Twin Roll Caster – TRC), respectivamente, passaram por caracterização mecânica via ensaio de tração (com corpos de provas extraídos a 0, 45 e 90° da direção de laminação) e caracterização estrutural e textura ao longo da espessura de chapas. Foram detectadas inclusões de alumina (Al2O3) e precipitados intermetálicos de Al3Fe juntos à matriz metálica e ambas as ligas apresentam as componentes cobre (112)[ 1 11 ¯], latão (“Brass”) {110}<112>, cubo (001)[ 0 10 ¯] e Goss {110}<001>, ao longo da espessura. A liga AA 5052 apresentou valores de coeficiente de anisotropia planar e normal superiores aos da liga AA 5050C, como também as propriedades mecânicas medidas em tração uniaxial.

“…Thin strips of Al-Mg alloys with less than 3 wt.% Mg [2,28] are also twin-roll cast in appropriate quality on an industrial scale. At the same time, TRC of strips of Al-Mg alloys with up to 4.5 wt.% Mg [32,33] is limited predominantly to laboratory scale. The industrial twin-roll casting of thin strips of age-hardenable alloys is limited to the alloy EN AW-6016 [34].…”

Al-Li based alloys are attractive materials for the aerospace industry. The twin-roll casting of such materials could provide properties not achievable by conventional direct-chill casting and downstream processing methods due to significantly higher solidification rates. An Al-Li-Cu-Mg-Zr alloy was twin-roll cast with the same alloy containing a small addition of Sc. The microstructure of as-cast materials and the influence of Sc on the behavior of the alloy at elevated temperatures were studied by means of light and electron microscopy and by resistivity measurements. A fine-grained structure was formed during twin-roll casting, but several surface and internal defects were found on the strips, which should be suppressed by a further adjustment of the casting conditions. The addition of Sc had a positive effect on grain size uniformity and microstructure stabilization at elevated temperatures, as shown by the precipitation of a fine dispersion of coherent Sc- and Zr-containing precipitates.

“…Many industries are intensively involved developing equipment for thin slab casting, where several models differ basically in shape and size of the mold, the kind submerse valve, kind and intensity of deformation applied on the solidification region, as well as the length and thickness of hot cut slab (Hoseinifar, Salari, & Nezhad, 2016).…”

In industrial casting operations, the possibility of implantation of a diversity of operational conditions has as consequence the generation of a wide range of solidification structures, affecting the mechanical properties and the quality of the final product. Due to the importance of the study of thin slabs solidification, for this work is used a system that allows the physical simulation of initial stages of continuous casting of thin slabs for laboratory experiments under several solidification conditions. Experiments were carried out using Pb-2.5% Sb alloy that presents low melting temperature and characteristic structure. For the Pb-2.5% Sb alloy thin slabs were obtained in cooled mold without reduction and with 10 and 20 mm reductions. It was found that the degree of deformation applied tends to increase the equiaxed region by the breakage of the dendrites as well as the possibility of the formation of equiaxed dendritic structures. It was observed that the deformation of this alloy directly influences the secondary dendrite spacing, tending to decrease it.
