Abstract

The mechanical response of a 7075/SiC/15% metal matrix composite is investigated by means of hot compression test. The flow stress curves obtained in temperature and strain rate ranges of 300 - 500 °C and 0.001-1.0 s-1, respectively in order to achieve the processing map of the studied material following the Dynamic Material Model. All zones of flow instability studied through an optical microscope. Microstructural characterization studies conducted on the compressed composite samples using an optical microscope image analyzer, revealed safe domains of dynamic recrystallization, elongation and nonsafe domains of adiabatic shear bands, interfacial ductile-tearing failure (debonding) of SiC Particles. The observations performed in order to describe the behaviour of the material under hot forming operations in terms of material damage and microstructural modifications.
