Usoro nrụpụta nke nnukwu ike bolts
1. Spheroidizing annealing nke elu-ike bolts
Mgbe a na-emepụta oghere isi hexagon site na usoro isiokwu oyi, nhazi mbụ nke ígwè ahụ ga-emetụta kpọmkwem ike ịmepụta n'oge nhazi isi oyi.Ya mere, ígwè ahụ aghaghị inwe ezigbo plasticity.Mgbe ihe mejupụtara kemịkalụ nke ígwè ahụ na-adịgide adịgide, nhazi metallographic bụ isi ihe na-ekpebi plasticity.A na-ekwenyekarị na pearlite na-adịghị ahụkebe adịghị akwado isi okwu oyi, ebe ọmarịcha pearlite nwere ike imeziwanye ikike nrụrụ plastik nke ígwè.
