Ihe na-esonụ na-ewebata ọtụtụ ikpe nke mgbapeka adịgboroja nke ihe adịghị mma kpatara.
(1)Na-akpụ akpụmgbawa na-akpata site na ntụpọ ingot

Ọtụtụ n'ime ntụpọ ingot nwere ike ime ka mgbawa n'oge a na-emepụta ihe, dị ka egosiri na Foto , nke bụ etiti mgbape nke 2Cr13 spindle forging.
Nke a bụ n'ihi na oke okpomọkụ kristal dị warara yana ọnụọgụ shrinkage linear dị ukwuu mgbe ingot 6T na-agbake.
N'ihi ezughị ezu condensation na shrinkage, nnukwu okpomọkụ dị iche n'etiti n'ime na n'èzí, nnukwu axial tensile stress, dendrite gbawara, na-akpụ a inter-axial mgbawa na ingot, nke a na-amụbawanye n'oge forging na-aghọ mgbawa na spindle forging.

Enwere ike iwepụ ntụpọ ahụ site na:
(1) Iji meziwanye ịdị ọcha nke mgbaze ígwè a wụrụ awụ;
(2) Ingot jụrụ nwayọọ nwayọọ, na-ebelata nrụgide okpomọkụ;
(3) Jiri ezigbo onye na-ekpo ọkụ na mkpuchi mkpuchi, mee ka ikike nke ijuputa shrinkage dịkwuo elu;
(4) Jiri etiti compaction forging usoro.

(2)Na-akpụ akpụmgbawa na-akpata site na mmiri ozuzo nke adịghị ọcha na nchara n'akụkụ oke ọka.

A na-ebukarị sọlfọ dị na ígwè n'akụkụ oke ọka n'ụdị FeS, ebe agbaze ya bụ naanị 982 ℃.N'ebe okpomọkụ dị elu nke 1200 ℃, FES na oke ọka ga-agbaze ma gbaa gburugburu ọka n'ụdị ihe nkiri mmiri mmiri, nke ga-ebibi njikọ dị n'etiti ọka ahụ ma mepụta fragility thermal, na mgbawa ga-eme mgbe obere mgbagwoju anya.

Mgbe ọla kọpa dị na ígwè na-ekpo ọkụ na ikuku peroxidation na 1100 ~ 1200 ℃, n'ihi nhọrọ oxidation, ebe ndị nwere ọla kọpa ga-etolite n'elu oyi akwa.Mgbe solubility nke ọla kọpa na austenite karịrị nke ọla kọpa, a na-ekesa ọla kọpa n'ụdị ihe nkiri mmiri mmiri na oke ọka, na-akpụ ọla kọpa brittleness na enweghị ike ịgha ụgha.
Ọ bụrụ na e nwere tin na antimony n'ime ígwè, a ga-ebelata ike nke ọla kọpa na austenite nke ọma, a ga-esiwanye ike ịmalite ịmalite.
N'ihi nnukwu ọla kọpa dị elu, a na-ahọrọ oxidized elu nke forgings nchara n'oge a na-ekpo ọkụ ọkụ, nke mere na ọla kọpa na-eme ka ọ baa ọgaranya n'akụkụ oke ọka, a na-emepụta mgbape na-emepụta site na nucleating na ịgbasa n'akụkụ akụkụ nke ọla kọpa bara ụba nke oke ọka.

(3)Ịme mgbawanke a na-ebute site na usoro dị iche iche (nkeji nke abụọ)

Ihe eji arụ ọrụ nke akụkụ nke abụọ na ígwè na-adịkarị iche na nke metal matrix, n'ihi ya, nrụgide ọzọ ga-eme ka usoro plasticity n'ozuzu ya belata mgbe nrụrụ na-aga.Ozugbo nrụgide mpaghara karịrị ike njikọ dị n'etiti usoro heterogeneous na matrix, nkewa ahụ ga-eme na oghere ga-emepụta.
Dịka ọmụmaatụ, oxides, nitrides, carbides, borides, sulfides, silicates na ndị ọzọ na ígwè.
Ka anyị kwuo na usoro ndị a dị oke.
Nkesa ụdọ, ọkachasị n'akụkụ oke ọka ebe ike njide na-adịghị ike dị, ịdị elu okpomọkụ ga-agbawa.
Ihe omimi nke macroscopic nke ịgbawa mgbawa nke ezigbo mmiri ozuzo AlN kpatara n'akụkụ oke ọka nke 20SiMn steel 87t ingots ka oxidized wee gosipụta ya dị ka kristal kọlụm polyhedral.
Ntụle a na-ahụ anya na-egosi na mgbawa a na-akpụ akpụ metụtara nnukwu oke mmiri ozuzo AlN n'akụkụ oke ọka bụ isi.

The countermeasures kagbochie forging crackingN'ihi mmiri ozuzo nke aluminom nitride tinyere kristal bụ ndị a:
1. Debe ọnụ ọgụgụ nke aluminom agbakwunyere na ígwè, wepụ nitrogen site na ígwè ma ọ bụ gbochie mmiri ozuzo AlN site n'ịgbakwunye titanium;
2. Nabata na-ekpo ọkụ nnyefe ingot na supercooled agba mgbanwe usoro ọgwụgwọ;
3. Dịkwuo okpomọkụ nri okpomọkụ (> 900 ℃) na ozugbo okpomọkụ forging;
4. Tupu forging, zuru ezu homogenization annealing na-rụrụ ime ka ọka ókè ọdịda na-adọ mgbasa.
