摘要：Automobile industries are using material substitution
for to build lighter weight, and fuel efficient engines, offering
better properties materials of engine components, including
engine poppet valves and valve seats. Valves and valve seats
are very important components that are used at high operating
temperature to control the flow and volumetric efficient at
desired level of engine performance. The present work
describes that Al-SiC composite as possible alternate materials
with its unique capacity to give required properties for engine
poppet valves and valve seats. Al-SiC MMC is prepared by
powder metallurgy and various casting techniques. In the
research a composite is developed by stir casting process by
using aluminium alloy with silicon carbide Nano particles and
substitute sintering operation at 600oC temperature for one
hour. Mechanical tests like microstructure, hardness, crushing
load, surface roughness, etc. are conducted.
