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 iji nweta ezigbo nhazi elu, na ụdi quenching adịghị mfe ịmepụta deformation cracks. Spheroidizing annealing kwesịrị ekwesị maka elu carbon ígwè na elu carbon alloy anwụ ígwè.
