Mune iri pepa, mhedzisiro ye cu melement pane yekubheka kuramba kwe 8011 Alloy Aluminium Foil yakadzidzwa neTensile Bvunzo, pinhole kuongorora, Metallographic Muedzo, uye kubheka kuramba. Migumisiro inoratidza kuti mushure mekuedza kubika pa 275 ℃ /75s, mukati meimwe nhanho, kugadzikana kwekushisa kwepamusoro kwe 8011 alloy inovandudzwa nekuwedzera kwekuteedzera Cu zvirimo mukati 8011 Alloy.

1.1 Test material
The the 8011 alloy casting uye rolling billets zvakasarudzwa sezvinhu zvekuedza, uye billet yaive 7.4mm*1140. The Cu zvirimo zvevatatu 8011 Alloys (8011-1, 8011-2, 8011-3) yakanga yakasiyana, uye kuumbwa kwezvimwe zvinhu kwakanga kusina kunyanya kusiyana.

1.2 Test plan
Iyo aluminium foil yekugadzira process inoyerera ndeye: kunyunguduka – kukanda nekukunguruka – kukunguruka kunotonhora – intermediate annealing – kucheka – foil rolling – kutsvedza – kurongedza.
Kunze kwekusiyana kweCu content, mamwe maitiro ekugadzira evatatu 8011 alloy aluminium foils inogadzirwa zvinoenderana neayo maitiro paramita. Iyo yakawanikwa yakapera aluminium foil yakaedzwa kuita uye kubheka bvunzo kuita zvichiteerana. Pamusoro pe, samples dzakatorwa kuti annealing test pa 180 ℃, 200 ℃, 220 ℃, 240 ℃, 260 ℃ uye 280 ℃ kwe3h.

Iyo pinhole uye dyne kukosha bvunzo yealuminium foil inoedzwa zvinoenderana nezvinopihwa zveGB3198-2010.. Iwo matatu alloy apedzwa samples akawanikwa akaiswa muchoto chimwe chete chemuffle yekubheka bvunzo. Maererano nezvinodiwa zvekushandisa zvevatengi, tembiricha yekubikira yekupikisa bvunzo yakaiswa 275 ℃, uye nguva yekubika i75s.
Tensile samples dzinoitwa zvinoenderana neGB3198-2010 standard, kureba kwegeji i100mm, uye akisi refu yemuenzaniso inofambirana negwara rekukunguruka. Tensile mienzaniso yakaedzwa paKD II-1 yemagetsi universal test muchina.

2 Miedzo mhinduro uye kuongorora
Iwo matatu alloys ane chimiro chakafanana uye hapana mukati mechimiro chakakanganisika sekupatsanurwa. Zviyo zvezviyo zvezviyo zvitatu hazvina kunyanya kusiyana, uye saizi yezviyo inenge 150 μm, iyo inosangana nezvinodiwa zvekutonhora kutenderedza maitiro uye annealing maitiro ealuminium foil substrates.

Kuti udzidze maitiro eCu zvemukati pane zvivakwa uye kubheka kuramba kwealuminium foil, mhando nhatu dze 8011 alloy aluminium foil zvigadzirwa zvine akasiyana Cu zvemukati zvakaedzwa zvemakanika zvivakwa uye kubheka bvunzo kuita kwezvakapera zvigadzirwa.. Vatatu 8011 Alloys vese vakasangana nechando chimwechete, intermediate annealing, uye foil rolling passs kuti uwane akapedzwa aruminiyamu foils ehukobvu hwakafanana. Kusimba kwekusimba kwealloy kwakaratidza kuwedzera kwemaitiro nekuwedzera kweCu content. Mushure mekuedza kubika, kusimba kwekusimba kwe 8011-3 alloy ine yakakwira Cu yemukati yakadzikira ne 24.1%, kusimba kwekusimba kwe 8011-2 alloy yakaderera ne 30.9%, uye kusimba kwesimba re 8011-1 alloy yakaderera ne 33.3% . Zvinogona kuonekwa kuti nekuwedzera kweCu content, kugadzikana kwekuita kwealloy mushure mekubika kunowedzera kuwedzera.

Mukuedza kubika, sezvo kubikira kwekubikira kwealuminium foil kwakabatana zvakanyanya neiyo recrystallization maitiro eiyo alloy, kuitira kuenzanisa uye kudzidza maitiro ekudzokorora evatatu 8011 Alloys, vatatu 8011 alloy yakapera zvigadzirwa zvakaiswa pasi 180 ℃, Annealing pa 200 ℃ , 220 ℃ , 240 ℃ , 260 ℃ , 280 ℃ kwe3h, zvabuda zvinoratidza kuti annealing kugadzikana kwe 8011-3 Alloy yakakwira kupfuura iyo ye 8011-2 uye 8011-1 Alloy, 8011 panguva imwechete yekupisa tembiricha uye nenguva. -3 alloys ane shoma recrystallization uye softening dhigirii.

Pamusoro pe, takaitisawo dyne value test uye pinhole bvunzo pamatatu 8011 Alloys. Mhedzisiro yemuyedzo inoratidza kuti dyne kukosha uye pinhole nhamba yeatatu alloys ese anosangana neyakajairwa.

For the 8011 Alloy, mukati meimwe nhanho, nekuwedzera kweiyo trace alloying element Cu zvemukati, iyo yakasimba mhinduro yekusimbisa mhedzisiro yakakura, saka simba rayo 8011-3 alloy yakapedzwa chigadzirwa chakakwira kupfuura icho che 8011-2 uye 8011-1 Alloys.

Cu inogona kuumba hushoma hweCuA12 musanganiswa nekunaya kwemhinduro yakasimba mualuminium alloy. Iyo CuA12 komputa ine isina kurongeka uye yakatsetseka chimiro, uye inoparadzaniswa zvishoma nezvishoma mumuganhu wezviyo muchimiro cheskeletal, iyo inobata basa mu dislocation pinning mune inotevera aluminium foil processing uye deformation maitiro; chikonzero ndechekuti Cu inonyanya kuvepo muchimiro chemhinduro yakasimba muAl, uye zviri nyore kuunganidza zvakapoteredza dislocations. Kuumbwa kweCoriolis air mass kunoderedza kukanganiswa kwelatisi, inoderedza kusangana kwe elastic pakati pe solute maatomu uye dislocation, inoita dislocations munzvimbo yakati dzikamei, inoderedza kuwanda kwezvinofambiswa dislocation, inotadzisa kubatanidzwazve kwe dislocations, uye inotadzisa kubatanidzwazve kwe dislocations. Crystal nucleation uye nucleation inokura, nokudaro kuwedzera simba realloy uye recrystallization tembiricha yeyakapera aluminium foil.

Chepiri, kuteedzera huwandu hweCu zvinhu zvinogona zvakare kuumba yechipiri nhanho, izvo zvinotadzisa kutama kwemukati kweiyo recrystallized nuclei uye kutadzisa kukura kwezviyo zvakadzokororwa.. Muchidimbu, mukati meimwe nhanho, kuwedzera zviri mukati meiyo trace alloying element Cu inogona kuwedzera tembiricha yekupisa yealloy uye kuvandudza kusimba kwekupisa kweiyo alloy.. Zvinogona kuonekwa kuti microalloying ndiyo imwe yenzira dzakakosha dzekuvandudza kupisa kwekupisa kwema alloys.

3 Mhedziso
1) The the 8011-3 Alloy uye 8011-2 alloy mushure mekuwedzera iyo Cu yemukati inogona kusangana nezvinodiwa nevatengi maererano neyakapedzwa mekiniki zvivakwa, pamusoro dyne, uye nhamba yemapinikoni.
2) Nekuwedzera kweCu content, kusimba kwekusimba kwe 8011 alloy zvishoma nezvishoma inowedzera; panguva imwe, iyo recrystallization tembiricha yealloy inowedzerawo zvishoma nezvishoma.
3) Mushure mekuedza kubika pa 240 ℃/75S, kusimba kwekusimba kwe 8011-3 alloy ine yakakwira Cu yemukati yakadzikira ne 24.1%, uye kusimba kwesimba re 8011-2 alloy yakaderera ne 30.9%; Kusimba kwakadzikira 33.3%. 8011-3 alloy inoratidza kushomeka kudiki muzvivakwa pane 8011-2 uye 8011-1. Kuwedzera iyo Cu yemukati kunobatsira kuvandudza kubikwa kwekubikira kweyakapedzwa aluminium foil.
