El Catálogo Colectivo reúne los registros del material que posee cada una de las
bibliotecas de la Universidad Nacional de Córdoba, pudiendo encontrarse colecciones
especializadas y actualizadas en todas las áreas del conocimiento; lo que permite una
amplia visibilidad y garantiza el acceso al patrimonio documental de la Universidad.
Se encuentra disponible para toda la comunidad académica: estudiantes, docentes,
egresados e investigadores.
Si formas parte de la comunidad de la UNC también podés solicitar préstamos de material,
a cualquier biblioteca universitaria, utilizando el servicio de préstamo interbibliotecario,
independientemente de la facultad a la que pertenezcas, la carrera que curses o la cátedra
que dictes.

In the first part of these notes we dealt with light alloys intended for the production of castings. We will now consider, under the designation of light alloys for forging, those which, in order to acquire the shape of parts, are previously subjected to considerable hot deformations, or as the French say, "corrodes" or in English "wroughts". Several processes are used for this elaboration, such as the hammer, the press, the rolling mill, the ''extrusion'' process, etc. It is the most common material used in aircraft construction, as it is received in factories in the form of sheets, strips, bars, profiles, tubes, wires, etc., or in ingots to be shaped by stamping. Among these alloys we will find some whose breaking load approaches or exceeds 40 kg. per mm.2., generally designated "high strength light alloys".
