1. Mechanical Properties and Crystallographic Texture of Symmetrical and Asymmetrical Cold Rolled IF Steels
Abstract The crystallographic texture developed during cold rolling and subsequent annealing of interstitial free sheet steels aims to increase conformability. For this, it is necessary to obtain partial α-fiber and continuous and homogeneous γ-fiber texture components. In this work, the influence of symmetric (SR) and asymmetric (AR) cold rolling on cryst

2. Otimização do corte de pontas de um aço livre de intersticiais laminado a quente usando tesoura do tipo guilhotina / Optimization the cut edge of a hot rolled interstitial free steel using a guillotine type shearing machine
The automotive industry\ s demand for high formability steels for use in exposed body panels motivated the development of several interstitial free (IF) steels specifications at Companhia Siderurgica Nacional. The \"IF-Ti\" steel specification belongs to the special deep drawing steels group (CSN EEP-IF), with yield strength <380 MPa, and among all grades of

3. Caracterização de fases intermetálicas presentes em aço galvanizado por imersão a quente com tratamento térmico do revestimento metálico
Hot dip galvanized steels with thermal treatment, or galvannealed steels, are used in automotive industries because of their properties of weldability, workability, and corrosion resistance. The hot dip galvanized steel with thermal treatment is called as galvannealed. The zinc layer of galvannealed steels have iron-zinc intermetallic phases, depending on th

4. Estudo sobre o pick-up de nitrogênio após a etapa de refino primário do aço
With the growing need of high quality steel there is a great demand for the development and production of steels with ever stringent chemical composition restrictions. For instance the presence of carbon and nitrogen in Interstitial Free steels for automobile industry. These restrictions are defined by the final application to which the product is destined.

5. Effect of Ti and Nb Additions on the Formation of Craters for IF Steel Galvanneal Coatings
Interstitial Free steels feature alloying elements present in an ultra low C matrix that account for C stabilization and consequently a high number of C free interstitials in a ferrite matrix that give these steels the ideal texture, low yield point, favorable plastic strain ratios, high elongation and n-value necessary for an ideal performance on forming pr

6. Avaliação da resistência à corrosão de aços IF revestidos com zinco e ligas de zinco-ferro destinados à industria automobilística
One of the most important changes in the last twenty years regarding steel application as a structural element, was the use of zinc and zinc-iron steel coated products for situations which require a major corrosion resistance. The consumer and competitor pressures responsible for the upsurge in the use of galvanized steel, which was experienced in the 1980s,

7. Influencia do processamento termomecanico na estrutura e nas propriedades mecanicas de um aço ultra-baixo carbono livre de intersticiais
Nos últimos anos, melhorias substanciais na tecnologia de fabricação de aços tornaram possível o desenvolvimento de aços de ultra-baixo carbono livres de intersticiais (interstitial free steels). Os aços IF apresentam teores de carbono menores que 50ppm, em peso, e são estabilizados com titânio e/ou nióbio, objetivando remover os elementos intersti
