The fracture resistence properties of a rod and a plate, both made of 2024 aluminium alloy, are evaluated according to standard and non-standard methods. The materials are tested after heat treatments involving material microstructures different especially as to size and dispersion of the hardening precipitates. The sensitivity of various fracture-toughness parameters to microstructure conditions, specimen geometry, as well as their interactions is analyzed. Correlations established between standard and non-standard parameters confirm that alternative testing procedures are adequate to evaluate the fracture toughness of this alloy. © 1985 Martinus Nijhoff Publishers.

Abstract
The fracture resistence properties of a rod and a plate, both made of 2024 aluminium alloy, are evaluated according to standard and non-standard methods. The materials are tested after heat treatments involving material microstructures different especially as to size and dispersion of the hardening precipitates. The sensitivity of various fracture-toughness parameters to microstructure conditions, specimen geometry, as well as their interactions is analyzed. Correlations established between standard and non-standard parameters confirm that alternative testing procedures are adequate to evaluate the fracture toughness of this alloy. © 1985 Martinus Nijhoff Publishers.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
