Influence of alumina and zirconia nanoparticles on mechanical properties and damping of magnesium

Magnesium polycrystals reinforced with 3 % (vol.) ZrO₂ nanoparticles and 3 % (vol.) AI2₂O₃ nanoparticles were deformed in tension at a constant strain rate at temperatures between 20 and 300°C. The yield stress of both materials decreases rapidly with temperature. The flow stress of Mg+AI2₂O₃ is hig...

Description
Summary:Magnesium polycrystals reinforced with 3 % (vol.) ZrO₂ nanoparticles and 3 % (vol.) AI2₂O₃ nanoparticles were deformed in tension at a constant strain rate at temperatures between 20 and 300°C. The yield stress of both materials decreases rapidly with temperature. The flow stress of Mg+AI2₂O₃ is higher than that of Mg+ZrO₂. Ductility of the composite with zirconia is substantially higher. The difference in the deformation behaviour of both composites is very probably caused by difference in bonding between matrix and ceramic nanoparticles.
