Study on fracture behaviour of Al–15%Mg2Si metal matrix composite with and without beryllium additions
Source abstract
Abstract
In this study, the influence of Beryllium (Be) content on the fracture behaviour of Al–15%Mg2Si composite was investigated. The results showed an increase in mechanical properties with increasing of Be content. The stress–strain curves of samples showed a same category of serrations reflecting non-uniform deformation. Scanning electron microscopy was employed to examine the crack nucleation and fracture model. The results indicate that Al–15%Mg2Si composite shows different behaviours of crack initiation and fracture for samples with and without Be. Differences observed in the fracture behaviour were attributed to microstructural changes as well as morphological aspects of primary Mg2Si particles.
