Investigation on the Production of Solution Strengthened Ductile Iron Part Grade 500-14

Öz

The aim of this study is investigating a new possibility instead of EN GJS 500-7 material. The new possibility is solution strenghted ductile iron EN GJS 500-14 with higher yield strength, higher elongation, low weight and low cost advantages. For the selected composition, whole mechanical and microstructural properties has been achieved. The thermal analyses and the computer simulation has been studied. Results showed good correlation between real casting results and computer simulation. Finally, EN GJS 500-14 casting material is replaceable for 500-7 in certain conditions; tensile, hardness, elongation and yield strength requirements. Keywords; solution strenghted ductile iron, casting simulation, thermal analyses
