Abstract

En el presente trabajo se determinan los valores de tenacidad a la fractura (KIC) de muestras de Acero 45 fundido,
empleando las correlaciones entre la tenacidad a la fractura y la energía de impacto (CVN) obtenida del ensayo de Charpy.
Se hace una discusión sobre las correlaciones que más se ajustan en la región de transición y en upper shelf. Se comparan
los valores obtenidos de estas correlaciones a valores de tenacidad a la fractura establecidos en la literatura.


Palabras claves: Fractura, energía de impacto, acero fundido.

Abstract.
In this paper, the values of fracture toughness (KIC) are determined on specimens of cast steel grade 45, using the
correlations among the fracture toughness (KIC) and the impact energy (CVN) obtained from a Charpy test. A discussion is
made on the correlations that are better adjusted in the transition region and in upper shelf region. The obtained values are
compared from these correlations to values of fracture toughness (KIC) settled down in the literature.


Key words. Fracture, impact energy, cast steel.
