1. Avaliação da influência da temperatura e ponto de orvalho no recozimento final de aços elétricos semiprocessados e totalmente processados / Evaluation of the influence of final annealing heat treatment temperature and dew point in semi-processed and fully processed electrical steels
Semi-processed electrical steels require annealing after processing in the motors manufactures to improve motors efficiency by reducing losses and increasing permeability. Annealing in fully processed electrical steel is performed to relax the residual stress and promote recovery or recrystallization of distorted parts. Commercial samples from different stee

2. Oxygen potencial effects on the oxidation sublayer and its influence on the magnetic properties of eletric steels after the final annealing heat treatment. / O efeito do potencial de oxigênio na oxidação subsuperficial e suas influências nas propriedades magnéticas de aços elétricos após o recozimento final.
Semi processed electrical steels, used for the manufacture of rotor and stator laminations are acquired from Steel Markers and after being punched in its final shape, must undergo an annealing heat treatment, which aims to improve the magnetic properties of the steel. If this heat treatment is carried out under inappropriate conditions, the dissolved element

3. 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
