Abstract : Brass is one of the most important domestic, industrial and ornamental alloy of Cu and Zn. Different compositions of brass ranging from Cu
wt% 60 to 80 are used wide over. In present study, brass in four compositions has been prepared by sand casting and optical micrography has
been done to compare the effect of composition on microstructure. The superheat temperature has also been varied in two steps viz. 980 oC
and 1100oC and the effect on microstructure has been reported.
