In the present work, the influence of alloying elements, on the mechanical characteristics and wear behavior by modification of the chemical composition of the ductile iron was studied, in order to improve these characteristics for the manufacture of agricultural tractors parts in particular front and rear axles, ploughshares, gear crankcase, pinions, transmission shafts, crankshafts, etc... The cast iron investigated was prepared in an induction furnace at 1500°C and inoculated with a ferro-silicon-magnesium to 45% Si and 10% Mg. The specimens were casted into self-hardening sand moulds at 1450°C, after an addition of alloying elements, Manganese (0.6%), Nickel (0.5%), Molybdenum (0.2%) and Vanadium(0.1%)) in the base spheroidal graphite cast iron produced. Various techniques, Optical microscopy, Microhardness, Hardness, Tensile strength, Impact resistance, and Wear tests (Wear resistance and Friction coefficient) were used to characterize these specimens. The obtained results show that the tested samples have ductile iron structures formed by ferrite and pearlite. Moreover, mechanical and wear tests prove that the alloyed cast iron has improved characteristics compared to unalloyed cast iron and shows the positive effect of alloying elements on these characteristics.

C ast irons are the most widely used engineering materials in the world with 71% of total metal casting all over the world, followed by non-ferrous and steel castings with 17% and 9%, respectively, following World Casting Census [1, 2]. Among the cast iron family, ductile, or spheroidal cast irons exhibit outstanding properties, such as castability, strength/weight ratio, and corrosion resistance [3]. With these well-developed features, the production of ductile iron was increased substantially in the last decade comparing with other cast iron groups [2]. Also, ductile irons are suitable for mass production such as components of windmills [4-6]. Whether the matrix of the ductile iron will be ferritic, pearlitic, or both, the type of graphite could be controlled with the addition of alloying elements [7-12]. Some other techniques, such as electromagnetic, ultrasonic vibrations were developed to modify the
