چکیده
The effect of aluminum (0, 2, 4, and 6 wt. %) copper on graphite morphology, microstructure compressive behavior ductile iron specimens manufactured by sand casting technique were investigated. morphology evaluated using optical microscopy (OM) scanning electron (SEM) equipped image processing software. To study the mechanical properties, compression test was conducted specimens. results indicated that surface fraction nodule count decreased when amount increased from 0 to 2 % after %. In addition, nodularity with increment amounts. By adding copper, decreased. addition ferrite pearlite in microstructure. increasing amounts stress vs. strain curves shifted upwards, modulus elasticity, yield strength, maximum stress, fracture improved. comparison had a greater influence properties iron.
