Ihame rya Homogenisation ya 6060 ya Aluminium

Niba imiterere ya mikoranike yo gukuramo idateganijwe nkuko byari byitezwe, mubisanzwe ibitekerezo byibanda kumurongo wambere wa bilet cyangwa ibihe byo gusaza / gusaza. Abantu bake ni bo bibaza niba homogenisation ubwayo ishobora kuba ikibazo. Mubyukuri, icyiciro cya homogenisation ningirakamaro mugutanga umusaruro mwiza. Kunanirwa kugenzura neza intambwe ya homogenisation bishobora kuganisha kuri:

Kwiyongera k'umuvuduko w'intambwe

Inenge nyinshi

Kuramo imiterere nyuma ya anodizing

Umuvuduko wo hasi

Properties Ibikoresho bibi

Icyiciro cya homogenisation gifite intego ebyiri zingenzi: gutunganya ibyuma birimo intermetallic fer, no kugabura magnesium (Mg) na silicon (Si). Mugusuzuma microstructure ya bilet mbere na nyuma ya homogenisation, umuntu ashobora kumenya niba fagitire izakora neza mugihe cyo gukuramo.

Ingaruka za Billet Homogenisation ku Gukomera

Muri 6XXX ikuramo, imbaraga ziva mubice bya Mg- na Si bikungahaye mugihe cyo gusaza. Ubushobozi bwo gukora ibi byiciro biterwa no gushyira ibintu mubisubizo bikomeye mbere yo gusaza gutangira. Kugirango Mg na Si amaherezo bibe igice cyigisubizo gikomeye, icyuma kigomba kuzimwa vuba kuva hejuru ya 530 ° C. Ubushyuhe buri hejuru yiyi ngingo, Mg na Si mubisanzwe bishonga muri aluminium. Ariko, mugihe cyo gukuramo, icyuma kiguma hejuru yubushyuhe mugihe gito. Kugirango Mg na Si byose bishonga, ibice bya Mg na Si bigomba kuba bito. Kubwamahirwe, mugihe cyo gukina, Mg na Si bigwa nkibinini binini bya Mg₂Si (Ishusho 1a).

Ubusanzwe homogenisation cycle kuri 6060 bilet ni 560 ° C mumasaha 2. Muri iki gikorwa, kubera ko bilet iguma hejuru ya 530 ° C mugihe kirekire, Mg₂Si irashonga. Iyo imaze gukonja, irongera igusha mu gukwirakwiza neza (Ishusho 1c). Niba ubushyuhe bwa homogenisation butari hejuru bihagije, cyangwa igihe ni gito cyane, ibice binini bya Mg₂Si bizagumaho. Iyo ibi bibaye, igisubizo gikomeye nyuma yo gukuramo kirimo Mg na Si nkeya, bigatuma bidashoboka gukora ubwinshi bwimvura igwa-biganisha kumikoreshereze yubukanishi.

Igishushanyo 1. Micrografi nziza ya optique ya 2% ya HF yuzuye 6060:

Uruhare rwa Homogenisation kuri Intermetallics irimo ibyuma

Icyuma (Fe) gifite ingaruka zikomeye kumeneka kuvunika kuruta imbaraga. Muri 6XXX ivanze, Fe ibyiciro bikunda gukora β -cyiciro (Al₅ (FeMn) Si cyangwa Al₈.₉ (FeMn) ₂Si₂) mugihe cyo gukina. Ibi byiciro ni binini, bingana, kandi bibangamira gusohora (byerekanwe ku gishushanyo cya 2a). Mugihe cyo guhuza ibitsina, ibintu biremereye (Fe, Mn, nibindi) birakwirakwira, kandi ibice binini byinguni biba bito kandi bizunguruka (Ishusho 2b).

Uhereye ku mashusho ya optique yonyine, biragoye gutandukanya ibyiciro bitandukanye, kandi ntibishoboka kubigereranya neza. Kuri Innoval, tugereranya bilet homogenisation dukoresheje imiterere yimbere yo gutahura no gutondekanya (FDC), itanga% α agaciro kumpapuro. Ibi bidushoboza gusuzuma ireme rya homogenisation.

Igishushanyo cya 2. Amashusho meza ya bilet (a) mbere na (b) nyuma yo guhuza ibitsina.

Uburyo bwo Kumenyekanisha no Gutondekanya (FDC) Uburyo

Igishushanyo cya 3a cyerekana icyitegererezo gisennye cyasesenguwe na scanning electron microscopie (SEM). Tekinike yerekana ibara ryerekana uburyo bwo gutandukanya no kumenya intermetallics, igaragara yera mubishusho 3b. Ubu buhanga butuma isesengura ryibice bigera kuri 1 mm², bivuze ko ibintu birenga 1000 byihariye bishobora gusesengurwa icyarimwe.

Igishushanyo cya 3.

Ibice bigize ibice

Sisitemu ya Innoval ifite ibikoresho bya Oxford Xplore 30 ikwirakwiza ingufu za X-ray (EDX). Ibi bituma icyegeranyo cyihuta cya EDX yerekanwe kuri buri kintu cyamenyekanye. Uhereye kuri iyi spekure, ibice bigize ibice bishobora kugenwa, hamwe na Fe: Si igereranyo.

Ukurikije Mn cyangwa Cr ibirimo amavuta, ibindi bintu biremereye nabyo birashobora kubamo. Kubintu bimwe 6XXX bivanze (rimwe na rimwe bifite Mn ikomeye), (Fe + Mn): Ikigereranyo cya Si gikoreshwa nkibisobanuro. Iyi mibare irashobora kugereranywa niyizwi Fe-irimo intermetallics.

phase -cyiciro (Al₅ (FeMn) Si cyangwa Al₈.₉ (FeMn) ₂Si₂): (Fe + Mn): Ikigereranyo cya Si ≈ 2. Porogaramu yacu yihariye itwemerera gushiraho urwego no gutondekanya buri gice nka α cyangwa β, hanyuma tugashushanya imyanya yabo muri microstructure (Ishusho 4). Ibi bitanga ijanisha ryagereranijwe ryahinduwe α mumatagisi ya homogenized.

Igishushanyo 4. (A) Ikarita yerekana ibice-

Icyo Data ashobora kutubwira

Igishushanyo cya 5 cyerekana urugero rwukuntu aya makuru akoreshwa. Muri iki kibazo, ibisubizo byerekana ubushyuhe budasanzwe mu itanura ryihariye, cyangwa birashoboka ko ubushyuhe bwateganijwe butagerwaho. Kugirango usuzume neza ibibazo nkibi, byombi impapuro zipimisha hamwe na fagitire yerekana ubuziranenge irakenewe. Bitabaye ibyo, ibyateganijwe% α urwego kubyo bihimbano ntibishobora gushingwa.

Igishushanyo cya 5. Kugereranya% α mu bice bitandukanye by itanura ridahuje igitsina.
