Ọ dị mkpa na-eduzi ọgwụgwọ okpomọkụ mgbeịgha ụghan'ihi na ebumnuche ya bụ ikpochapụ nrụgide dị n'ime mgbe ịghachara ya. Gbanwee ike ịgha mkpụrụ, melite arụmọrụ ịkpụ; A na-anụcha ọka ndị na-adịghị ahụkebe na usoro ịhịa aka n'ahụ na otu iji kwadebe microstructure nke akụkụ maka ọgwụgwọ okpomọkụ.

1. Igwe ọkụ dị elu: belata ike siri ike, belata ma ọ bụ wepụ nrụgide na-akpata mgbe ị na-eme ka ọ dị jụụ, meziwanye plasticity na ike. Kwesịrị ekwesị maka alloy ígwè na elu hardness mgbe normalize.

2.

3. Isothermal annealing: nweta ihe edo edo karia mkpochapụ zuru oke, kpochapụ nrụgide nrụgide nke ọma, belata ike. Na nnukwu forgings dị mkpa, a pụkwara iji ya gbasaa hydrogen ma gbochie mmepụta nke ntụpọ ọcha. N'iji ya na ntachi obi zuru oke, ọ nwere ike belata oge nkwụsịtụ ma melite arụmọrụ mmepụta.

4. Nhazi: enwere ike nweta pearlite kacha mma iji mee ka nzukọ ahụ dị mma; Meliteforgingsike na ike, belata nrụgide dị n'ime, melite ịrụ ọrụ ịkpụ; Maka eutectoid ígwè. Enwere ike ikpochapụ carbide ntupu.

5 spheroidization annealing: iji nweta spherical cementite na ferrite Ọdịdị, ọ bụghị nanị na-ebelata ike ike, na na ịcha usoro dị mfe na-eji ire ụtọ nhazi elu, na ụdi quenching adịghị mfe na-emepụta deformation cracks. Spheroidizing annealing kwesịrị ekwesị maka elu carbon ígwè na elu carbon alloy anwụ ígwè.
