Influence Of Different Nano-Sized Tio2 Particles On Lm0 Al-Alloy On Mechanical Behaviour Of Nano Metal Matrix Composite

Abstract

— The Aluminium metal matrix Nano composites can be used in numerous applications because of
their Excellent Mechanical, Tribological Properties and Light Weight. To enhance the performance of
composite matrix in aluminium alloy metal is reinforced with Nano particles in the matrix of alloy
uniformly, which ameliorates composite properties without affecting limit of ductility. The paper presents
the results of experimental investigation on mechanical properties of Various Nano sizes of Particles of 25
and 60 Nano meter Titanium-di-oxide (TiO2-p) particles reinforced with LM0 aluminium metal matrix. The
influence of reinforced ratios of 0, 4, 8 and 12 wt. % of TiO2-p on mechanical properties was examined. It is
commonly accepted that decreasing the reinforcement size improves mechanical properties of the
composites for a given particle volume fraction, because of the smaller inter-particle spacing and larger
work hardening rate. The decrease in the particle size increases both the effects of direct strengthening and
indirect strengthening. The composites were synthesized by Stir Casting method by using bottom pouring
muffle furnace and Magnesium was added to the melt in order to improve the wettability of the composites.
Care has to be taken while synthesis of composites because as the Particle size decreases the clustering and
agglomeration is seen in the composite. Influence Various
