Ubungakanani beenkozo bubhekisa kubungakanani beenkozo ngaphakathi kwekristale yobungakanani beenkozo. Ubungakanani beenkozo bunokubonakaliswa ngummandla ophakathi okanye umyinge wedayamitha yeenkozo. Ubungakanani beenkozo bubonakaliswa libakala lobungakanani beenkozo kwimveliso yamashishini. Ubungakanani obuziinkozo ngokubanzi bukhulu, oko kukuthi, kokukhona kucolekileyo kokona kulungileyo. Ngokutsho kwenqaku elilandelayo, ndiyathemba ukuba inokukunceda ukuba uqonde ubungakanani beenkozo ze-forgings. Ndiyakholelwa ukuba baqhelene nobukhulu obuziinkozo be-forgings, ke akufuneki sazi kakhulu malunga nobungakanani beenkozo ze-forging.
I-deformation yeplastiki ye-forgings iphula i-crystals ye-dendritic engundoqo kwaye inefuthe elibalulekileyo lokucokisa ukutya okuziinkozo. Ngakolunye uhlangothi, kukho inkqubo yokubuyisela kwakhona ngexesha lokuguqulwa kweplastiki kwiqondo lokushisa eliphezulu. Ngexesha lobushushu eliphezulu deformation yeplastiki, ubungakanani eziziinkozo zeforgingsemva kokuba i-recrystallization inqunywe ngubushushu, i-deformation degree kunye nesantya. Ngoko ke, ubukhulu beenkozo zeforgingsefunyenwe ngeenkqubo ezahlukeneyo zokubumba yahlukile.
Iimpawu eziphambili zoomatshini bokubumba ngeenkozo ezirhabaxa kukuba iplastiki yabo kunye nokuqina kwabo kuphantsi kakhulu kunezo zineenkozo ezintle. Ukucokisa iinkozo ngonyango lobushushu akwanelanga kuphela umsebenzi onzima kwaye kuneendleko, kodwa kunzima kakhulu kwaye akunakwenzeka kwezinye iintsimbi zealloy. Ngoko ke, ingqiqoukwenzainkqubo yamabakala athile ensimbi kufuneka isetyenziswe ngokuhambelana nomzobo we-recrystallization wokusebenza okushushu.
Ukuphakama kweqondo lobushushu lokubumba, ubukhulu besayizi yeenkozo ze-forging emva kokwenziwa kwakhona. Ngoko ke, ubushushu bokugqibela bokubumba kufuneka buncitshiswe kangangoko kunokwenzeka ukuze kuqinisekiswe ukucocwa okuziinkozo phantsi komqathango wokuba i-forgings ayiyi kuvelisa ubushushu obuphantsi bokubumba ukuqhekeka. Nangona kunjalo, kunzima kakhulu kwi-forgings enkulu ukuqinisekisa ubushushu obuphantsi bokugqibela obusezantsi kuzo zonke iindawo zokubumba okufanayo. Oku kunokwenziwa kuphela ngamava nobuchule babasebenzi abanobuchule.
Ngexesha elithileukwenzaubushushu, kukho idigri yedeformation ebalulekileyo. Xa isidanga deformation ingaphakathi kolu luhlu, ukhozo recrystallized of fii-orgingsirhabaxa noko. Ngoko ke, iqondo lokuguqulwa ngexesha lokubumba, ngakumbi kumlilo wokugqibela, kufuneka ligwenywe ngokusemandleni ngaphakathi kwinqanaba elibalulekileyo lokuguqulwa.
Ukhozo alufani lubhekisa kwezinye iindawo zenkozo yokubunjwa irhabaxa ngakumbi, ezinye iindawo zincinci. Esona sizathu siphambili sobukhulu obungalinganiyo beenkozo kukuba ukuguqulwa kokungalingani kwebillet kwenza ukuba idigri yokuqhekeka kweenkozo ihluke, okanye idigri ye-deformation yendawo yengingqi iwela kwindawo ebalulekileyo yokuguqulwa, okanye ukuqina komsebenzi wendawo ye-superalloy, okanye indawo yendawo. ubungakanani beenkozo ezirhabaxa xa ucima kwaye ufudumeza. Iintsimbi ezikwaziyo ukumelana nobushushu kunye ne-superalloys zinovelwano ngakumbi kwi-inhomogeneity yeenkozo. Ubungakanani obungalinganiyo beenkozo buya kunciphisa ukuqina kunye nokusebenza kokudinwa kwe-forging.
Eli nqaku lichaza ubukhulu becala malunga nobukhulu beenkozo ze-forgings. Ndiyathemba ukuba iya kuba luncedo kuwe.
