MukuruKukanganisika, apo hunhu hwezvinyorwa zvisina kurwadza kana kurongeka hazvisi panguva chaiyo, kukanganwira matsau zvinowanzoitika zviri nyore kuitika.
Izvi zvinotevera zvinosuma zviitiko zvinoverengeka zvekuregerera kupaza zvakakonzerwa nezvinhu zvisina kunaka.
(1)Kukanganisikamarara anokonzerwa neingot kuremara

Zvizhinji zvezvirongwa zvinogona kukonzera kupaza panguva yekuregerera, sezvakaratidzwa mumufananidzo, iyo iri central crack ye2cr13 spindle yekuregerera.
Izvi zvinodaro nekuti iyo crystallization tembiricha yakamanikana yakamanikana uye iyo linear shrinkage coefficien yakakura yakakura kana iyo 6t inggot solid.
Nekuda kwekukwana kusakwana uye kuderera, kusiyanisa kukuru kwemukati nekunze, iyo denrtite yakakwenenzverwa, iyo yakawedzera kuparara panguva yekukanganisika mukukanganisika kuve kupaza mumashure.

Urema hunogona kubviswa ne:
(1) kuvandudza kuchena kwekunyungunuka simbi yekunyungudutsa;
(2) ichingotonhorera zvishoma, ichidzora kushushikana kwemvura;
(3) Shandisa yakanaka yekupisa mumiririri uye insulation cap, wedzera kugona kwekuzadza shrinkage;
(4) Shandisa iyo cent cent compaction kukoshesa maitiro.

(2)Kukanganisikamarara anokonzerwa nekutsvagirwa kwekukuvadza kusvibiswa kwesimbi mumiganhu yezviyo.

Sarufa iri simbi inowanzo kuve yakagadzirirwa pamwero wetsiva muchimiro cheFes, ane pollt point ingori 982 ℃. Pakuregerera tembiricha 1200

Kana ndarira iri muSimbi inopisa mune yePeroxidation mamiriro kuna 1100 ~ ,, Kana solubility yemhangura muAustenite inodarika iyo yemhangura, mhangura inogoverwa muchimiro chemvura yemvura paGiera, achigadzira mhangura bross uye kutadza kuumbwa.
Kana paine tini neanotarisira musimbe, iyo solubility yemhangura muAustenite ichaderedzwa zvakanyanya, uye tsika yekuzvibata ichave yakawedzerwa.
Nekuda kwezvakakosheswa nenzvimbo dzepamusoro, pamusoro pekuregerera zvesimbi zvakasarudzwa zvekuregerera pakuregerera, kuti mhete yakamisikidzwa, uye kupaza kupaza kwakaumbwa nekuwedzera uye kuwedzera mhangura-yegoridhe chikamu chezviyo.

(3)Kukanganisika kupazainokonzerwa nenheteragenious chikamu (chechipiri chikamu)

Zvivakwa zveChina zvechipiri chikamu chesimbi chinowanzove chakasiyana kwazvo neicho chesimbi matrix, saka kusagadzikana kwekuwedzera kuchaita kuti huwandu hwepazasiketi kuderera kana kuremara kuchiyeredza. Kana kushushikana kwenzvimbo kunodarika simba rekusunga pakati peiyo heterogenious chikamu uye matrix, kuparadzaniswa kuchaitika uye maburi anoumbwa.
Semuenzaniso, nziyo dzokurwa, nitides, dzinotakura, dzikatanga, dzinokudza, solicides, siriki uye zvichingodaro nesimbi.
Ngatitii zvikamu izvi zvakazara.
Chain Kugovera, kunyanya pamwe chete muganho wezviyo uko kune isina kusimba simba riripo, kupisa kwakanyanya kukanganwira kuchakanganisa.
Macroscopic morphology yekukanganisika kupaza yakakonzerwa neakanaka Aln Litary pamwe ne 20simn Steel 87t Ingots uye yakapihwa sePolyhedral coldcur makristasi.
Ongororo yeMicroscopic inoratidza kuti kukanganisika kunoenderana nehuwandu hwehuwandu hwezviyo zvakanaka zvezviyo zvine mutsindo.

Zvimedu zvedzivirira kukanganisika kupazainokonzerwa nekunyorerwa kweAluminium nitride pamwe nekristaro ndeyekutevera:
1. Gara iyo huwandu hwe aluminium yakawedzerwa kusimbi, bvisa nitrogen kubva simbi kana kuti inhibit aln yekunyepedzera nekuwedzera titanium;
2. Tora HOT HOT DEPTUGY ingot uye yakashongedzwa chikamu cheshandura maitiro ekurapa;
3. Wedzera kupisa kwekupa tembiricha (> 900 ℃) uye inopisa zvakananga kuramba;
