Forging txheej txheem txheej txheem yuav ntsib ntau yam teeb meem, tshwj xeeb peb saib cov ncauj lus kom ntxaws qhia cov neeg ua haujlwm.
Ib qho, aluminium alloy oxide zaj duab xis:
Cov oxide zaj duab xis ntawm aluminium alloy feem ntau yog nyob rau ntawmtuag forgedlub vev xaib, nyob ze ntawm qhov chaw parting. Qhov saum npoo ntawm cov pob txha muaj ob tus yam ntxwv: ua ntej, nws yog tiaj tus thiab cov xim txawv ntawm cov nyiaj-grey thiab lub teeb daj mus rau xim av thiab tsaus xim av; Qhov thib ob, cov pob me me, compact thiab ci. Cov oxide zaj duab xis ntawm aluminium alloy yog tsim thaum lub molten nto cuam tshuam nrog dej vapor los yog lwm yam hlau oxides nyob rau hauv cov huab cua thaum melting thiab forging. Nws yog tsim nyob rau hauv cov kua hlau koom nrog hauv cov txheej txheem casting. oxide zaj duab xis nyob rau hauvforging qhov chawthiab tuag forgings tsis muaj qhov cuam tshuam loj rau cov khoom siv kho tshuab ntev.
Ob, carbide segregation:
Raws li kev txheeb xyuas ntawm Hebei Forging Works, carbide segregation feem ntau tshwm sim nyob rau hauv cov hlau alloy nrog cov ntsiab lus siab carbon, uas yog tus cwj pwm los ntawm ntau lub zos carbides tsub zuj zuj, feem ntau vim hais tias cov leaustenite eutectic carbides thiab lwm yam network carbides nyob rau hauv cov hlau tsis tawg thiab sib npaug zos rau hauv. txheej txheem ntawm qhib forging. Carbide segregation yuav txo cov forging deformation muaj peev xwm ntawm cov hlau, nyob rau hauv cov txheej txheem ntawm hluav taws yooj yim ua rau tawg, kev kho cua sov thiabquenching forgingsyooj yim rau overheat thiab quenching, txiav cuab yeej yooj yim rau tawg.

Peb, kab ci ntsa iab:
Cov kab ci ntsa iab yog cov kab nyias uas muaj kev cuam tshuam thiab siv lead ua ci ntsa iab ntawm qhov ntev ntawm qhov tawg thaum lub sij hawm forging, feem ntau yog faib thoob plaws hauv cov pob txha thiab feem ntau tshwm sim ntawm cov axis. Cov kab ci ntsa iab feem ntau tshwm sim los ntawm kev sib cais ntawm alloy. Cov kab ci me me tsis tshua muaj kev cuam tshuam rau cov khoom siv kho tshuab ntawm cov khoom siv, thiab cov kab ci ntsa iab loj yuav txo cov plasticity thiab toughness ntawm cov ntaub ntawv.
Cov saum toj no yog kev qhia txog qee qhov teeb meem uas tau ntsib hauv kev ua forging, yog tias muaj lwm cov lus nug, thov nrog peb tham.
