Ductile cast iron round bars were prepared using alloys with carbon equivalent percentage (C.E) ranging between 4.50 % and 4.76 %. Different measurements were carried out on as – cast and heat-treated specimens. Ductile cast iron is essentially a family of materials with a wide verity of properties which are satisfactory for different engineering(More)
