Pengaruh Pusaran pada Proses Nodullarisasi Besi Cor Bergrafit Bulat terhadap Kekuatan Tarik

Ferro casting ductil (FCD) group from cast iron decant,easy it is to make cheap and the it belongs to the nature mechanical much the same to with the conventional steel. This cast iron manyweared upon which substitution become militant speciallyfor the component of otomotip. Many ways to increase the nature of fisis and mechanical among others by giving mixing materials at the of process nodullarisasi, ther method vortex is one of the ways of processes nodularisasi which developed recently. The tensile strenght 50 kg mm:, insenion ( l -11, 6 kg mm: is obtainedfrom this research, by the addition of the streght this method is hoped to he used infoundry indusrri metal. Key Words: Ductile.
