Abstract
Nowadays in the current domain, manufacturing
industries are competing to reduce the cost and fuel
consumption rates. Especially, in automobile and aerospace
applications because of the improvement of lightweight metal
advantages. Magnesium, aluminum and other few materials
are considered as lightweight materials to use in required
applications due to their inherent properties. Therefore, in this
paper tried to characterize the advances of LM20 aluminum
alloy rods by using the die-casting processes at various
processing temperatures followed by room temperature, 373 K,
and 473 K. The main aim is to study the effect of various
processing temperature on microstructures and mechanical
properties of LM20 alloy. Also, this paper reveals the stability
of the microstructures of LM20 aluminum alloy though the
processing temperature has been increased. The tensile
strength, hardness of the LM20 aluminum alloy was decreased
with increase in processing temperature. Similarly, the wear,
and surface roughness tests were performed on the LM20 alloy
rods to understand the effect at various processing
temperature.
