Hoolei one hao

ʻO ka hao hoʻoheheʻe e pili ana i ka hao i hoʻoheheʻe ʻia ka graphite ma hope o ka mālama ʻia ʻana o ka hao i hoʻoheheʻe ʻia me kahi mea hana spheroidizing. ʻO ia ke kumu i kapa ʻia ai ka ductile cast iron i ka spheroidal graphite cast iron a i ʻole nodular cast iron. I loko o ka ductile cast iron e electron microsope, he spherical ke ʻano o ka graphite spheroidal, a he ʻano radial kona loko, a loaʻa iā ia ka hopena polarization. ʻO ka helu spheroidization e pili ana i ka pākēneka o ka huina o ka graphite spherical ma kekahi ʻano i ka huina o ka graphite. ʻO ka helu spheroidization kahi helu helu e ana i ka māka spheroidization o ka nodular cast iron, a he mea koʻikoʻi ia i nā hoʻolei hao ductile.
