| Abstract |
Casting thickness influences mechanical property and graphite shape in ductile cast iron and the results from this study are as follows: 1) The strength and the hardness were decreased rectilinearly as the casting size increased from Ø25㎜ to Ø100㎜ and were nearly same at the size of Ø100㎜ and 150㎜. 2) The strength and the hardness were appeared homogeneous in every step bar of the same thickness. 3) The best ductility was obtained at Ø50㎜. 4) The maximum diameter of huge graphite nodule was 130㎛. |
