Isothermal forging of AA2618 + 20% Al2O3 by means of hot torsion and hot compression tests

The isothermal forming of AA2618 + 20% Al2O3 was studied by employing hot torsion and hot compression tests in the temperature and strain rate ranges of 350–500 °C and 10-3-1 s-1 strain rate, respectively. The processing and stability maps of the material were calculated following the dynamic material model leading to identification of the best forming conditions. The constitutive equations were calculated for the studied material and the damage produced by forming operation was calculated in all the test conditions. Both optical and scanning electron microscopy were used to evaluate the microstructural evolution of the material.
