Heerkulka rogrogmida kulul ee aluminiumyada aluminiumku waxa uu caadi ahaan ka sarreeyaa heerkulka wax-soo-saarka. Duubista kulul waa farsamaynta farsamaynta ee ku lug leh qallafsanaanta balaastikada ee birta heerkulka sare si loo gaaro qaabka iyo sifooyinka la doonayo.. Heerkulka rogrogmida kulul ayaa guud ahaan ka sarreeya heerkulka adag ee daawaha, hubinta balaastiga ku filan qallooca. Wixii aluminium aluminium ah, heerkulka rogrogmi kara wuxuu caadi ahaan ku dhacaa heerkul sare, inta badan aad u badan 500 darajo Celsius, iyada oo ku xidhan halabuurka daawaha iyo sifooyinka.

Annealing, dhanka kale, waa habka daawaynta kulaylka ka dib rogid kulul (iyo mararka qaarkood hababka shaqada qabow) taas oo ujeedadeedu tahay in lagu hagaajiyo qaab dhismeedka crystal iyo sifooyinka birta iyadoo lagu kululeynayo heerkul hoose ka dibna si tartiib ah u qaboojinaya, taas oo meesha ka saaraysa walbahaarka gudaha iyo kordhinta ductility. Heerkulka xuubka ayaa caadi ahaan ka hooseeya heerkulka gariirada kulul, guud ahaan ka hooseeya heerkulka adag ee daawaha, waxayna ku kala duwan tahay iyadoo ku saleysan daawaha gaarka ah iyo waxqabadka la doonayo.
Hoos waxaa ku yaal miis la fududeeyay oo soo koobaya heerkulbeegyada aluminiumka ee taxanaha kala duwan. Jadwalkani waxa uu ujeedadiisu tahay in uu bixiyo tixraac degdeg ah oo ku saabsan kala duwanaanshaha guud ee heerkulka annealing ee ku habboon noocyada kala duwan ee aluminium aluminium. Xusuusnow, heerkulka saxda ah iyo habka laga yaabaa in kala duwanaansho ku salaysan ka kooban alloy gaar ah iyo hantida kama dambaysta ah ee la doonayo.
Taxanaha Aluminium Aloy | Sharaxaada | Heerkulka Heerkulka ee Annealing |
1xxx Taxane | Aluminium saafi ah | 345°C ilaa 415°C (650°F ilaa 775°F) |
2xxx Taxane | Aluminium-Copper Alloys | 413°C ilaa 483°C (775°F ilaa 900°F) |
3xxx Taxane | Aluminium-Manganese Alloys | 345°C ilaa 410°C (650°F ilaa 770°F) |
4xxx Taxane | Aluminium-Silicon Alloys | Kala duwan; tixraac daawaha gaarka ah |
5xxx Taxane | Aluminium-Magnesium Alloys | 345°C ilaa 410°C (650°F ilaa 770°F) |
6xxx Taxane | Aluminium-Magnesium-Silicon Alloys | 350°C ilaa 410°C (660°F ilaa 770°F) |
7xxx Taxane | Aluminium-Zinc Alloys | 343°C ilaa 477°C (650°F ilaa 890°F) |
8xxx Taxane | Aluminium alloys oo leh walxo kale | Aad bay u kala duwan tahay; inta badan 345°C ilaa 415°C (650°F ilaa 775°F) Alloys gaar ah sida 8011 |
Shaxdani waxa ay ku siinaysaa dulmar ballaadhan. Si loo helo xaaladaha baab'inta saxda ah, oo ay ku jiraan waqtiyada qoynta iyo heerarka qaboojinta, la talinta waxyaabaha ku qeexan walxaha ama khabiir biraha ah ayaa lagula talinayaa. Shuruudaha gaarka ah waxay si weyn u saameyn karaan sifooyinka qalabka iyo ku habboonaanta codsiyada kala duwan.
Xiritaanka gariiradaha aluminiumku waa habka daaweynta kulaylka caadiga ah
Marka la soo koobo, Heerkulka kulkululku wuu ka sarreeyaa heerkulka jilbiska sababtoo ah rogid kulul waxay u baahan tahay birta inay noqoto caag ku filan oo qallafsan heerkulka sare., halka soo saarista ay diirada saarayso wanaajinta qaab dhismeedka crystal iyo guryaha waxaana sida caadiga ah lagu qabtaa heerkul hoose.
