For the purpose of investigating the effect of microstructural constituents on the mechanical properties of Fe-C-Al cast iron, the tensile properties, changes in hardness and variation of primary austenite dendrite morphology were investigated.
The results obtained from this experiment are summarized as follows.
Tensile strength appeared to be increased with increasing the directionality of primary austenite, the maximum tensile strength was obtained for the specimen containing 3% C and 4.4% Al.
With increasing the Al content the tensile strength was shown to be increased at the constant carbon content but decreasing tendency of the tensile strength was shown over the carbon content of 4%.
Tensile strength was increased with increasing the carbon content at all Al level.
At same tensile strength, hardness was decreased with increasig the Al content.
The factors controlling the tensile strength and hardness appeared to the primary austenite and pearlite in the matrix, respectively.
