Ƙayyadaddun ƙayyadaddun sinadarai na bayanan bayanan alloy na 6082 na aluminium a cikin jeri guda uku an ƙaddara ta amfani da sikirin karantawa kai tsaye na Swiss ARL, kamar yadda aka nuna a cikin Table 3.
2.1 Gwajin Aiki
Don kwatantawa, an yi nazarin aikin bayanan martaba na kewayon abun ciki guda uku tare da hanyoyi daban-daban na quenching, sigogi iri ɗaya na extrusion, da matakan tsufa.
2.1.1 Aikin Injini
Bayan tsufa na wucin gadi a 175 ° C na tsawon sa'o'i 8, an ɗauki daidaitattun samfurori daga hanyar extrusion na bayanan martaba don gwajin tensile ta amfani da na'urar gwajin lantarki ta Shimadzu AG-X100. Ayyukan injina bayan tsufa na wucin gadi don abubuwan ƙira daban-daban da hanyoyin kashewa ana nuna su a cikin Tebura 4.
Daga Table 4, ana iya ganin cewa aikin injiniya na duk bayanan martaba ya wuce daidaitattun ƙimar ƙasa. Bayanan bayanan da aka samar daga 6082-Z alloy billlets suna da ƙananan haɓaka bayan karaya. Bayanan martaba da aka samar daga 6082-7 alloy billlets sun sami mafi girman aikin injina. 6082-X alloy profiles, tare da daban-daban m hanyoyin mafita, nuna mafi girma yi tare da m sanyaya hanyoyin quenching.
2.1.2 Lankwasawa Gwajin Aiki
Yin amfani da na'urar gwaji ta duniya ta lantarki, an gudanar da gwaje-gwajen lanƙwasawa mai maki uku akan samfurori, kuma an nuna sakamakon lanƙwasawa a cikin Hoto 3. Hoto na 3 ya nuna cewa samfuran da aka samar daga 6082-Z alloy billlets suna da bawon lemu mai tsanani a saman kuma suna fashe a kan baya na lankwasa samfurori. Kayayyakin da aka samar daga 6082-X alloy billlets sun sami kyakkyawan aiki na lankwasa, filaye masu santsi ba tare da kwasfa na lemu ba, kuma ƙananan fasa a wurare da aka iyakance ta yanayin geometric a bayan samfuran lanƙwasa.
2.1.3 Babban Dubawa Mai Girma
An lura da samfurori a ƙarƙashin na'urar gani na gani na Carl Zeiss AX10 don nazarin ƙananan ƙananan abubuwa. Sakamakon bincike na microstructure na nau'o'in nau'in nau'i na nau'i na nau'i na nau'i na nau'i guda uku an nuna su a cikin Hoto 4. Hoto na 4 yana nuna cewa girman hatsi na samfurori da aka samar daga sandar 6082-X da 6082-K alloy billets sun kasance kama, tare da ƙananan ƙwayar hatsi a cikin 6082-X. alloy idan aka kwatanta da 6082-y gami. Kayayyakin da aka samar daga 6082-Z alloy billlets suna da girman hatsi masu girma da yadudduka masu kauri, wanda cikin sauƙi ya haifar da bawon lemu da raunin haɗin ƙarfe na ciki.
2.2 Binciken Sakamako
Dangane da sakamakon gwajin da ke sama, ana iya ƙarasa da cewa ƙira na kewayon abun ciki na gami yana tasiri sosai ga microstructure, aiki, da haɓakar bayanan bayanan da aka fitar. Ƙara yawan abun ciki na Mg yana rage ƙyallen alloy kuma yana haifar da samuwar fashewa yayin extrusion. Mafi girma Mn, Cr, da abun ciki na Ti suna da tasiri mai kyau a kan tace ƙananan ƙananan abubuwa, wanda hakan yana tasiri tasiri mai kyau a saman, aikin lankwasawa, da kuma aikin gaba ɗaya.
