| description | Metal matrix composites are engineered materials combine two or more
materials, one of which is a metal, where the tailored properties can be attained
by systematic combination of different constituents. A variety of methods
available for producing these advanced materials includes the conventional
casting process which is considered as the easiest processing technique.
Preparation of these composite materials by foundry technology have the
unique benefit of near-net shape fabrication in a simple and cost effective
manner. Besides, casting processes lend themselves to manufacture large
number of complex shaped components of composites at a faster rate required
by the automotive, transportation, sports and other consumer oriented
industries. In this study, quartz-silicon dioxide particulate reinforced LM6 alloy
matrix composites were fabricated by carbon dioxide sand molding process by
varying the particulate addition by volume fraction on percentage basis. Tensile
and hardness tests and scanning electron microscopic studies were conducted
to determine the maximum load, tensile strength, modulus of elasticity and fracture surface analysis to characterize the morphological aspects of the test
samples after tensile testing. Hardness values are measured for the quartz
particulate reinforced LM6 alloy composites and it has been found that it
gradually increases with increased addition of the reinforcement phase. The
tensile strength of the composites decreases with the increase in addition of
quartz particulate. In addition, particulate-matrix bonding and interface studies
have been conducted to understand the mechanical behavior of the processed
composite materials and it were well supported by the fractographs taken by
the scanning electron microscope. The fractographs taken after the tensile test
illustrates the particle pullout from the matrix due to lack of bonding and load
deformation characteristic mechanism. |
