Isayensi edumile: indawo yokuncibilika yama-alloys e-aluminium

Uhlolojikelele

I-Aluminium iyinsimbi emangalisayo, eyaziwa ngokuguquguquka kwayo, ukusebenza, kanye nezakhiwo ezingasindi. Ngephuzu lokuncibilika eliphakeme ngokwanele ukuba lisebenzise inqwaba yezinhlelo zokusebenza, akumangalisi ukuthi lesi sakhi singeyesithathu ngobuningi kakhulu oqweqweni loMhlaba kanye nensimbi engeyona insimbi esetshenziswa kakhulu ngemva kwensimbi.. Kulokhu okuthunyelwe kwebhulogi, sizohlola indawo yokuncibilika kwe-aluminium, imiphumela yayo kuma-alloys e-aluminium ahlukene, izici ezithinta lesi sakhiwo esibucayi, izicelo zayo, nokuthi iqhathaniswa kanjani nezinye izinsimbi.

i-aluminium encibilikisiwe

Ishadi Lephuzu Elincibilikayo Lama-Aluminium Alloys

Iphuzu lokuncibilika kwe-aluminium liyimpahla eyisisekelo ethinta ukusetshenziswa kwayo ezimbonini ezihlukahlukene. Indawo encibilikayo ye-aluminium emsulwa ingu-660.32°C (1220.58°F). Nokho, lapho ezinye izakhi zengezwa ukwenza ama-alloys e-aluminium, indawo yokuncibilika ingashintsha. Okulandelayo ishadi lamaphuzu ancibilikayo lochungechunge oluyisishiyagalombili lwama-alloys e-aluminium enziwe mbumbulu:

Uchungechunge	I-Melting Point (°C)	I-Melting Point (°F)
1000 I-Aluminium yochungechunge	643 – 660	1190 – 1220
2000 Uchungechunge lwe-Aluminium Alloy	502 – 670	935 – 1240
3000 Uchungechunge lwe-Aluminium Alloy	629 – 655	1170 – 1210
4000 Uchungechunge lwe-Aluminium Alloy	532 – 632	990 – 1170
5000 Uchungechunge lwe-Aluminium Alloy	568 – 657	1060 – 1220
6000 Uchungechunge lwe-Aluminium Alloy	554 – 655	1030 – 1210
7000 Uchungechunge lwe-Aluminium Alloy	476 – 657	889 – 1220

Lobu bubanzi bubonisa ukuthi ukungezwa kwama-elementi e-alloying kungashintsha kakhulu indawo yokuncibilika ukuze ifanele izinhlelo zokusebenza ezithile.

Amaphuzu Ancibilikayo Wezinto Ezivamile Ze-Aluminium

Uchungechunge oluyisishiyagalombili lwe-aluminium forged forged alloy lunamabanga athile asetshenziswa kakhulu. Ithebula elilandelayo likhetha ezinye zazo ukuze zibonise ububanzi bephoyinti elincibilikayo elihambisanayo:

Imodeli ye-alloy	Uchungechunge	I-Melting Point (°C)	I-Melting Point (°F)
1050	1000	646 – 657	1190 – 1210
1060		646.1 – 657.2	1195 – 1215

Izinto Ezithinta Iphuzu Lokuncibilika Le-Aluminum

Izici eziningana zingathonya iphuzu lokuncibilika kwe-aluminium nama-alloys ayo:

Izinto ze-alloying: Ukuba khona kwezakhi ze-alloying njengethusi, i-magnesium, i-silicon, futhi i-zinc ingakhuphula noma yehlise indawo yokuncibilika, kuye ngokusebenzisana kwabo ne-aluminium.
Ukungcola: Ngisho nenani elincane lokungcola lingathinta indawo encibilikayo. Ngokwesibonelo, insimbi, okuvame ukuba khona njengokungcola, lingehlisa izinga lokuncibilika.
Umlando Oshisayo: Umlando oshisayo we-aluminium, okuhlanganisa noma yikuphi ukwelashwa okudlule okushisayo noma ukucutshungulwa, ingacwenga ukwakheka okusanhlamvu futhi ithinte iphuzu lokuncibilika.
Amasu Okucubungula: Amasu okucubungula ahlukene, njengokuqiniswa okusheshayo noma i-powder metallurgy, kungaholela ku-non-equilibrium microstructures enamaphuzu ahlukene okuncibilika.

Izicelo ze-Aluminium's High Melting Point

Iphuzu eliphezulu lokuncibilika kwe-aluminium kanye nama-alloys ayo kuwenza afanelekele uhla lwezinhlelo zokusebenza ezishisa kakhulu.:

Welding kanye Brazing: Iphuzu eliphakeme lokuncibilika kwe-aluminium livumela amasu okushisela aqinile kanye nama-brazing, ezibalulekile ekwakhiweni kwezakhiwo eziyinkimbinkimbi nezingxenye.
Izishintshi Zokushisa: Iphoyinti eliphezulu lokuncibilika lama-alloys athile e-aluminium liwenza alungele ukusetshenziswa kwizishintshisi zokushisa, lapho bekwazi ukumelana namazinga okushisa aphezulu okusebenza ngaphandle kokuncibilika.
Izinto zokupheka: Indawo ephezulu yokuncibilika kwe-aluminiyamu nayo inenzuzo ekwenzeni izinto zokupheka, ukuqinisekisa ukuthi amabhodwe namapani angakwazi ukumelana namazinga okushisa aphezulu okupheka ngaphandle kwengozi yokuncibilika.

I-Aluminium Melting Point Iqhathaniswa Nezinye Izinsimbi

Uma kuqhathaniswa nezinye izinsimbi, indawo yokuncibilika ye-aluminium ayiphezulu. Nakhu ukuqhathanisa amaphuzu okuncibilika kwe-aluminium nezinye izinsimbi ezimbalwa ezivamile:

Insimbi	I-Melting Point (°C)	I-Melting Point (°F)
I-Aluminium	660.32	1220.58
Ithusi	1085	1981
Insimbi	1538	2800
Zinc	419	776
Insimbi	1370 – 1520 (kuyahlukahluka)	2502 – 2760 (kuyahlukahluka)

Lokhu kuqhathanisa kukhombisa ukuthi ngenkathi i-aluminium inephuzu eliphansi lokuncibilika kunezinsimbi ezifana nensimbi nensimbi, iphakeme kunezinc nezinye izinsimbi eziningi. Lokhu kubeka i-aluminium endaweni evumayo ezinhlelweni zokusebenza ezidinga ibhalansi phakathi kokumelana nezinga lokushisa eliphezulu nokusebenza kahle.

Ekuphetheni, indawo yokuncibilika kwe-aluminium iyimpahla ebalulekile ethonya ukusetshenziswa kwayo ezimbonini ezihlukahlukene. Ukuqonda izinto ezithinta lesi sakhiwo nokuthi siqhathaniswa kanjani nezinye izinsimbi kubalulekile ekukhethweni kwezinto ezibonakalayo nasekuthuthukiseni inqubo.. Iphuzu lokuncibilika eliphezulu le-aluminium, kuhlanganiswe nezinye izici zayo ezizuzisayo, iyenza ibe yimpahla eguquguqukayo yohlelo olubanzi lwezinhlelo zokusebenza.
