Saizi yezviyo inoreva saizi yezviyo mukati mesaizi yekristaro.Saizi yezviyo inogona kuratidzwa neavhareji nzvimbo kana avhareji dhayamita yezviyo.Saizi yezviyo inoratidzwa negiredhi saizi yezviyo mukugadzirwa kwemaindasitiri.General saizi yezviyo yakakura, ndiko kuti, iyo yakatsetseka ndiyo iri nani.Maererano nechinyorwa chinotevera, ndinovimba inogona kukubatsira kuti unzwisise saizi yezviyo zvefogi.Ini ndinotenda kuti vanoziva saizi yezviyo zvefogi, saka isu hatifanirwe kuziva zvakawanda nezve saizi yezviyo zvefogi.
Iyo yepurasitiki deformation yefogi inotyora coarse primary dendritic crystals uye ine yakakosha mhedzisiro yekunatsa zviyo.Kune rumwe rutivi, kune recrystallization maitiro panguva yepurasitiki deformation pakupisa kwakanyanya.Munguva yekupisa kwepurasitiki deformation, saizi yezviyoforgingspashure recrystallization inotarirwa tembiricha, deformation dhigirii uye kumhanya.Naizvozvo, saizi yezviyoforgingsinowanikwa nenzira dzakasiyana dzekugadzira zvakasiyana.

Iwo makuru emuchina ezvimiro zvefogi ane coarse zviyo ndezvekuti mapurasitiki avo uye kuomarara kwakadzikira zvakanyanya pane izvo zvine zviyo zvakanaka.Kuchenesa zviyo nekurapa kwekupisa hakusi kungoshanda-yakanyanya uye kunodhura, asiwo kwakaoma zvakanyanya uye hazvigoneke kune mamwe masimbi alloy.Naizvozvo, zvine musoroforgingmaitiro emamwe magiredhi esimbi anofanirwa kugadzirwa maererano nerecrystallization dhizaini yekushanda kunopisa.
Iyo yakakwira tembiricha yekugadzira, inokura saizi yezviyo zvefogi mushure mekugadzirisazve.Naizvozvo, tembiricha yekupedzisira yekugadzira inofanira kudzikiswa zvakanyanya sezvinobvira kuti ive nechokwadi chekunatswa kwezviyo pasi pemamiriro ekuti mafogi haaburitse tembiricha yekubikira mutswe.Nekudaro, zvakanyanya kuomera kune akakura forgings kuti ave nechokwadi chakafanana chakaderera chekupedzisira chekugadzira tembiricha munzvimbo dzese dzefogi imwechete.Izvi zvinogona kuitwa chete neruzivo uye hunyanzvi hwevashandi vane hunyanzvi.
Pane imwe nguvaforgingtembiricha, pane yakakosha deformation degree renji.Kana iyo deformation degree iri mukati meiyi chiyero, iyo yakadzokororwa tsanga yeforgingsyakakora zvishoma.Nokudaro, dhigirii yekushandura panguva yekugadzira, kunyanya mumoto wekupedzisira, inofanira kudziviswa sezvinobvira mukati mehutano hwakaoma hwekugadzirisa.
Zviyo hazvina yunifomu zvinoreva zvimwe zvikamu zvezviyo zvefodya zvakanyanya kukora, zvimwe zvikamu zvidiki.Chikonzero chikuru chekukura kwezviyo zvisina kuenzana ndechekuti kusaenzana kweiyo billet kunoita kuti dhigirii rekutsemuka kwezviyo risiyane, kana deformation yenzvimbo yenzvimbo inowira kunzvimbo yakaoma deformation, kana basa renzvimbo kuomarara kweiyo superalloy, kana yenzvimbo. saizi yezviyo yakaoma kana ichidzima nekudziya.Masimbi anodzivirira kupisa uye superalloys anonyanya kunetseka kune zviyo inhomogeneity.Saizi yezviyo isina kuenzana inoderedza kusimba uye kuneta kuita kwemafogi.
Ichi chinyorwa chinonyanya kutaura nezvehukuru hwezviyo zvefogi.Ndinovimba zvichabatsira kwauri.
