SUAREZ, M.A. et al. Procesamiento y caracterización de aceros microaleados calmados al aluminio. Rev. mex. fis. [online]. 2009, vol.55, n.6, pp.472-476. ISSN 0035-001X.

A series of microalloyed aluminium-killed steels stabilized with titanium, were made by means of the route of electrical arc furnace, vacuum degasser, secondary refinement and steel solidified into a continuous casting process. The resultant samples were hot rolling at 1100°C, cooled in air down to 650°C during 30 minutes, and cooled to room temperature. The resultant samples were cold rolled at room temperature and annealed at 700°C. In their microstructural, texture and mechanical properties evaluation, the re-crystallized samples showed mechanical properties similar to those used in the automotive industry.
