Microstructural Study of Heat Treated Chromium Alloyed Grey Cast Iron ()
Abstract
This work investigated the effect of annealing, normalizing and quenching heat treatments on the
microstructure of some chromium alloyed grey cast iron.
Three sets of ten samples each having chromium contents of 0.5, 1.5 and 2.5% were heat treated
above the upper critical temperature, to austenitizing temperatures (800℃, 850℃, 900℃) for
one hour each and then annealed, normalized and water quenched. Metallographic analyses of
the heat treated samples were done. The results showed carbides content increased with
increasing Chromium addition.
