Abstract

Here we investigate the mechanical behavior of the MnTiO3 ceramic. Nanoindentation tests in a manganese titanate polycrystalline sample were performed using a Berkovich indenter with a tip radius of 150 nm. On applying the load, it shows the elastic and plastic behavior. The work done during the elastic and plastic processes are 16757.78 {\mu}N.nm and 10045.72 {\mu}N.nm, respectively. The estimated values of reduced modulus and hardness are 158GPa and 10.5GPa, respectively. This suggests that this compound exhibits a significant plastic character.
