In the present research work, liquid state technique is employed to prepare the LM4/RHA/TiO2 composites containing
four different mass proportion of RHA and TiO2. The weight proportion of reinforcements ie RHA-1,3&5 and TiO2 2,5&6
respectively. Hybrid composite with 3% of RHA and 6% of TiO2 showed the maximum Tensile strength of 298.37 N/mm².It is
found that there is 37 % increase of tensile strength while addition of RHA and TiO2 to LM 24.The aluminium based
particulate reinforced composite, the dislocations are generated during solutionizing due to thermal mismatch between the
matrix and the ceramic reinforcement particles. It can be inferred that the tensile strength increased with an increase in the
weight percentage of rice husk ash and TiO2. Because, the RHA particles act as barriers to the dislocations when taking up the
load applied.
