Article Preview

The present study investigated the effect of copper and nickel together on ductile iron. Ductile iron was produced by the sandwich method using induction furnace installed at local commercial foundry. Heats without copper & nickel and with copper 0.5 wt% and 1.0 wt% nickel in combination were made. Tensile samples were machined from Y Block castings. Tensile test was performed to find out the effect of copper and nickel together on tensile strength of ductile iron. Effect of austempering heat treatment was also studied to find out the effect of copper and nickel in combination on tensile strength. The samples were austenitized at 900 oC for one hour and austempered at 270 oC and 370 oC. It was found that with the addition of copper and nickel the tensile strength of ductile iron increased. The tensile strength was more than double when the samples were subjected to austempering heat treatment at 270°C.
