Ithonya lezinqubo zokwelashwa kokushisa ezinhlakeni ze-microskuva kanye nemishini yokuphela kwama-aluminium alloy acloy

Ukugeleza kwenqubo yokukhiqiza

Amabha wokuhlola angama-6082 acaciswe ngu-Ф1mm. Isitsha sokukhishwa esikhiqizwayo saba nobubanzi be-Ф170mm nge-4-hole design design we-4-hole deffience kanye ne-coeffeed ekhishini ye-18.5. Ukugeleza kwenqubo ethile kufaka phakathi ukufudumeza i-Ingot, ukukhishwa, ukuqondisa okuqondile, ukwelula okuqondisa nokusampula, ukuqina kwe-roller, ukuqina kokugcina, ukuhlolwa kwekhwalithi, nokulethwa kwekhwalithi.

Izinjongo ze-3.Experimental

Inhloso yalolu cwaningo bekuwukukhomba amapharamitha wokushisa okushisa okushisa kanye namapharamitha wokushisa wokushisa athonya ukusebenza kwamabha we-6082-T6, ekugcineni afezeke izidingo ezijwayelekile zokusebenza. Ngokusho kwamazinga, izakhiwo zemishini emide ka-Alvel202 Alloy kufanele zihlangabezane nezincazelo ezisohlwini lweThebula 2.

Indlela ye-4.Experimental

4.1 Ukushisa Ukushisa Kokwelashwa Kwezokwelapha

Uphenyo lokushisa lokushisa lokushisa ngokukhethekile lugxile kakhulu emiphumeleni yokushisa kokushisa kwe-INGOT yokushisa kanye nokushisa kwesitsha sokukhishwa kwezakhiwo zemishini. Izinketho ezithile zepharamitha zichazwe kuThebula 3.

4.2 Isixazululo Esiqinile Nophenyo Lokushisa Lokushisa Lokushisa

Umklamo wokuhlola we-orthogonal waqashwa kwikhambi eliqinile nenqubo yokuguga lokushisa ukushisa. Amazinga akhethiwe anikezwa kuThebula 4, netafula le-orthogonal design likhombe njenge-IJ9 (34).

I-5.Results nokuhlaziywa

5.1 Ukukhishwa kwesilinganiso sokushisa imiphumela yokuhlola nokuhlaziywa

Imiphumela yokuhlolwa kokushisa kokushisa kokushisa kwethulwa kuThebula 5 nakumfanekiso 1. Kuthathwe amasampula ayisishiyagalolunye eqenjini ngalinye, futhi kwanqunywa izilinganiso zokusebenza kwemishini ezimisiwe. Kususelwa ekuhlaziyweni kwe-metallographic kanye nokwakheka kwamakhemikhali, kwasungulwa irejimeni yamakhemikhali: Ukuqedwa ngo-520 ° C imizuzu engama-40 nokuguga ngo-165 ° C amahora angu-16 amahora angu-12. Ukusuka etafuleni 5 futhi Umdwebo 1, kungabonakala ukuthi njengoba izinga lokushisa le-INCOT INOTOT yokushisa nokushisa kwesitsha sokukhishwa kwe-Ingot kukhuphuke, womabili amandla ashukumisayo futhi akhuphuke kancane kancane. Imiphumela emihle yatholakala emazingeni okushisa akwa-450-500 ° C kanye nokushisa kwesitsha sokukhishwa esingu-450 ° C, ahlangana nezidingo ezijwayelekile. Lokhu kungenxa yomphumela wokuqina kokusebenza okubandayo emazingeni okushisa aphansi aphansi, okubangela ukumiswa kwezinhlamvu zokugcina okusanhlamvu kanye nokuvusa isisombululo esiqinile phakathi kwe-A1 ne-MN ngesikhathi sokushisa ngaphambi kokuqala, okuholela ekuvuseleleni kabusha, okuholela ekuvuseleleni kabusha. Njengoba izinga lokushisa lokukhishwa likhuphuke, amandla okugcina RM womkhiqizo athuthuke kakhulu. Lapho izinga lokushisa le-Extrowlesion lisondela noma lidlule izinga lokushisa le-Ingot, ukuguquguquka okungalingani kwehle, kunciphisa ukujula kwamasongo anamaqabunga anamaqabunga kanye nokwandisa amandla wesivuno RM. Ngakho-ke, amapharamitha afanelekayo ukwelashwa kokushisa kokushisa yilezi: Ukushisa kwe-INGOT CREXTSION CRESSTION of 450-500 ° C nokushisa kwesitsha sokushisa esingu-430-450 ° C.

5.2 Isixazululo Esiqinile Nemiphumela Yokuhlola Emigqemeni Yokuguga Northogonal

Ithebula 6 lembula ukuthi amazinga afanele yi-A3B1C2D3, aqede ngo-520 ° C, izinga lokushisa lokufanisa eliphakathi kwamahora ayi-16, okuholela ekugugeni kwamahora ayi-12. Inqubo yokuqothula yakha isixazululo esiqinile. Emazingeni okushisa aphansi aphansi, ukugcwala kwesixazululo esiqinile esinamandla kuyancipha, kuthinta amandla. Ukushisa okuqothuka okungama-520 ° C kuthuthukisa kakhulu umphumela wokuqina okuqinile - ukuqiniswa kwesisombululo esiqinile. Ukuphumula phakathi kokuguga okuhlanzekile nokuguga, okungukuthi, isitoreji sokushisa segumbi, kuthonya kakhulu izakhiwo zemishini. Lokhu kukhulunywa ngokukhethekile izinduku ezingazelulwa ngemuva kokucima. Lapho isikhathi sokuphumula phakathi kokugunda nokuguga sidlula ihora eli-1, amandla, ikakhulukazi amandla okuthela, anciphe kakhulu.

5.3 Ukuhlaziywa kweMetallographic Missuntructure

Ukuhlaziywa okuphezulu kanye nokuhlaziywa kwama-poliarid kwaqhutshwa kumabha we-6082-T6 kumazinga okushisa aqinile wesisombululo samazinga okushisa angama-520 ° C no-530 ° C. Izithombe eziphakeme kakhulu ziveze umfaniswano wezulu ongenayo ngenhlayiya yesigaba eyisisekelo ehlukahlukene isatshalaliswe. Ukuhlaziywa kokukhanya kwe-polarized usebenzisa imishini ye-axiovert200 kukhombise umehluko ohlukile ezithombeni zesakhiwo sokusanhlamvu. Indawo ephakathi ibonise okusanhlamvu okuncane futhi okufanayo, ngenkathi imiphetho ikhombisa ukubhekelwa kabusha okusanhlamvu okuphezulu. Lokhu kungenxa yokukhula kwe-crystal nuclei emazingeni okushisa aphezulu, kwakha ama-precipitate ahlanganayo.

Ukuhlolwa kokuzijwayeza kwe-6.Production

Ekukhiqizweni kwangempela, izibalo zokusebenza kwemishini zenziwa ngamabhathi angama-20 emigoqo nama-20 amaphrofayili amaphrofayili. Imiphumela iboniswa kumatafula 7 no-8. Ekukhiqizweni kwangempela, inqubo yethu yokukhishwa kwenhlangano yenziwa emazingeni okushisa aphumela kumasampula e-T6, kanti ukusebenza kwemishini kuhlangane namanani aqondiwe.

 

7.Conclusion
