Caracterização Mecânica e Análise Microestrutural de Chapas Obtidas pelo Processo de Tailor Welded Blank (TWB)

Abstract: Resumo Um dos maiores desafios da indústria automobilística, a nível global, trata-se de desenvolver veículos que sejam, simultaneamente, leves e resistentes mecanicamente. O Tailor Welded Blank (TWB) surge como solução, pois é um processo que permite a soldagem de topo de chapas de diferentes especificações (material, espessura e/ou revestimento), antes da conformação. Nesta pesquisa trabalhou-se com chapas de aços livre de intersticiais (IF –Intertitial Free), da Companhia Siderúrgica Nacional (CSN), de códi… Show more

“…The behavior presented by the rupture load pro le is consistent with that found by [19], which rea rms his theory that the maximum resistance of a TWB does not depend on the weld (as long as it is previously quali ed), and is more related to the materials that make up the plates that give rise to the blank. This goes against what is advocated by [14,21,22].…”

“…As indicated by [19], there is a behavior that is somewhat interesting: the shear stress is the same for complementary angles (such as 15º and 75º, for example). It is noteworthy that this does not depend only on Eq.…”
