Inta lagu jiro habka adkeyn ee shubista, guud ahaan waxaa jira saddex meelood oo ku yaal qaybteeda iskutallaabta, kuwaas oo kala ah aagga adag, aagga adkeynta, iyo aagga dareeraha.
Aagga adkeysigu waa meesha ay "adag iyo dareere ku wada nool yihiin" inta u dhaxaysa aagga dareeraha iyo aagga adag. Balaadhkeeda waxa loo yaqaan ballaca aagga adkaynta. Baaxadda aagga adkeynta ayaa saameyn weyn ku leh tayada wax lagu shubo. Habka adag ee wax lagu shubo wuxuu ku salaysan yahay ballaca aagga adag ee lagu soo bandhigay qaybta iskutallaabta ee dhejinta, waxaana loo qaybiyaa lakab-lakab-lakab ah adkeynta, adkeynta dhejiska, iyo adkeyn dhexdhexaad ah.
Aynu eegno sifooyinka hababka xoojinta sida lakabka-lakabka adag iyo adkeynta dhejiska.
Lakab-lakab adag adkaynta: Marka ballaca aagga adkeysigu uu aad u cidhiidhi yahay, waxa iska leh habka adkaynta lakabka-lakabka. Xagga hore ee adkeyntiisu waxay si toos ah ula xiriirtaa birta dareeraha ah. Biraha ka tirsan aagga adag ee cidhiidhiga ah waxaa ka mid ah biraha saafiga ah (naxaas warshadeed, zinc warshadaha, daasadaha warshadaha), aluminiumyada eutectic (aluminium-silicon alloys, u dhow-eutectic alloys sida birta cawlan), iyo alaabo leh kala duwan crystallization cidhiidhi ah (sida. birta kaarboon yar). , naxaas aluminium, naxaas leh kala duwan crystallization yar). Kiisaska birta ah ee kor ku xusan dhamaantood waxay ka tirsan yihiin habka adkeynta lakabka-lakabka.
Marka dareeruhu ku adkeysto xaalad adag oo hoos u dhaco mugga, waxaa si joogto ah u buuxin kara dareeraha, iyo u janjeersiga soo saarista yaraanshaha kala firdhiyey waa mid yar, laakiin godadka yaraynta xoogga leh ayaa ka tagaya qaybta ugu dambeysa ee adag ee shubista. Godadka yaraynta xoogga leh waa sahlan tahay in la baabi'iyo, sidaas darteed sifooyinka dhimista ayaa wanaagsan. Dildilaaca intergranular ee ay sababto yaraanshaha xanniban ayaa si fudud loogu buuxiyaa bir dhalaalaysa si ay u bogsiiso dildilaaca, sidaa darteed tuurista ayaa u janjeerta dildilaaca yar. Waxa kale oo ay leedahay awood buuxin wanaagsan marka adkeyntu dhacdo inta lagu jiro habka buuxinta.
Waa maxay xinjirowga koollada: Marka aagga xinjiruhu uu aad u ballaaran yahay, waxay ka tirsan tahay habka xinjirowga dhiigga. Biraha ka tirsan aagga adag ee ballaaran waxaa ka mid ah aluminium aluminium, alloys magnesium (aluminium-copper alloys, aluminium-magnesium alloys, alloys magnesium), Alloys copper (bronze, bronze aluminium, naxaas leh heerkul aad u ballaaran), birta-carbon alloys (birta kaarboonka sare, birta ductile).
Baaxadda aagga adkaynta birta, way sii adkaanaysaa xumbooyinka iyo ku darida birta dhalaalaysa inay sabbeeyaan oo ka saaraan inta lagu jiro shubista, sidoo kale way adag tahay in la quudiyo. Kaabista ayaa u nugul dildilaaca kulul. Marka dildilaacyadu ka dhex dhacaan kirisdhisyada, laguma buuxin karo bir dareere ah si loo bogsiiyo. Marka nooca daawaynta noocan ahi ay adkaato inta lagu jiro habka buuxinta, awooddeeda buuxintu sidoo kale waa liidataa.
Waa maxay adkeysi dhexdhexaad ah: Xoojinta u dhaxaysa aagga adag ee cidhiidhiga ah iyo aagga adag ee ballaaran waxaa loo yaqaannaa aagga adag ee dhexdhexaadka ah. Alloys ka tirsan aagga adag ee dhexdhexaadka ah waxaa ka mid ah birta kaarboon, birta manganese sare, naxaas gaar ah iyo bir cad oo cad. Sifooyinkeeda quudinta, dabacsanaanta kulaylka iyo awoodda buuxinta caaryada waxay u dhexeeyaan adkaynta lakabka-lakabka iyo dhejinta hababka adkeynta. Xakamaynta adkeysiga noocan ah ee shubista inta badan waa in la hagaajiyo xuduudaha habka, in la dhiso heerkul wanaagsan oo ku habboon qaybta iskutallaabta ee shubka, la yareeyo aagga adkeysi ee qaybta iskutallaabta tuurista, oo beddel habka xoojinta ka soo-celinta adag ee lakabka -lakab-lakab adkeynta si loo helo kabo tayo leh.
