Ihe nkedo aja aja Ductile Iron

Ígwè úkwù na-ezo aka n'ígwè nkedo nke graphite na-adị okirikiri ma e jiri ihe na-emepụta ihe na-eme ka ígwè a wụrụ awụ gwọọ ya. Ya mere a na-akpọkwa ígwè nkedo ductile spheroidal graphite cast iron ma ọ bụ ihe nkedo nodular. N'ime igwe nkedo ductile site na microsope eletrọn, ọdịdị nke graphite spheroid bụ ihe dị okirikiri, na ime ya bụ ọdịdị radial, ọ nwekwara mmetụta polarization doro anya. Ọnụọgụ spheroidization na-ezo aka na pasent nke ngụkọta ọnụ ọgụgụ graphite dị okirikiri n'otu ebe ruo na mkpokọta graphite. Ọnụọgụgụ spheroidization bụ ndenye iji tụọ ọkwa spheroidization nke igwe nkedo nodular, na ọ bụ ọkọlọtọ dị mkpa na nkedo nkedo ductile.
