Kuleli phepha, Umphumela we-CU element ekumelaneni kokubhaka kwe 8011 I-Alloy Aluminium Foil yafundwa ngokuhlolwa kweTensile, Ukuhlolwa kwePinhole, Isivivinyo seMetallographic, nokungamelana nokubhaka. Imiphumela ikhombisa ukuthi ngemuva kokuhlolwa kokubhaka at 275 ℃ / 75s, ngaphakathi kwebanga elithile, ukuqina okushisa okuphezulu kwe 8011 I-Alloy ithuthukisiwe ngokwanda kokuqukethwe kwe-CU 8011 ingxubevange.
Amathegi: 8011 ingxubevange; Ngento ethile; Ukuphikiswa kwe-BAK
1 ukuqulwa
1.1 Isivivinyo sokuhlola
Le khasi 8011 I-Alloy Casting kanye ne-Rolling Ballts bakhethwa njengezinto zokuhlola, futhi imali ekhokhwayo kwakungu-7.4mm * 1140. Okuqukethwe kwe-CU kwabathathu 8011 ama-alloys (8011-1, 8011-2, 8011-3) bekuhlukile, Futhi ukwakheka kwezinye izinto bekungafani kakhulu.

1.2 Uhlelo lokuhlola
Ukugeleza kwenqubo yokukhiqiza ye-aluminium foil: ukubhebhe – Ukuphonsa nokugoqa – ukugoqa okubandayo – Ukuvela okuphakathi – ukunquma – rolling rolling – ukushiswa – ukuwowapha.
Ngaphandle komehluko kokuqukethwe kwe-CU, ezinye izinqubo zokukhiqiza zalaba abathathu 8011 I-Alloy Aluminium Foils ikhiqizwa ngokuya ngamapharamitha enqubo efanayo. I-aluminium foil etholakele etholakele yahlolelwa ukusebenza kokusebenza nokubhaka ngokulandelana. Ngaphezu kwalokho, amasampula athathwe ukuhlolwa okuvuselelwa kuyo 180 ℃, 200 ℃, 220 ℃, 240 ℃, 260 ℃ Futhi 280 ℃ nge-3h.

Ukuhlolwa kwenani le-pinhole ne-dyne ye-aluminium foil kuhlolwe ngokuya ngezinhlinzeko ze-GB3198-2010. Amasampula amathathu aqediwe aqediwe atholwe abekwe esithandweni esifanayo sokuhlola ukubhaka. Ngokuya ngezidingo zangempela zokusebenzisa amakhasimende, Izinga lokushisa lokuhlolwa kokumelana nokubhaka kusethelwe 275 ℃, nesikhathi sokubhaka singama-75s.
Izinhlobo ze-Tensile zenziwa ngokuya nge-GB3198-2010 Standard, Ubude be-gauge ngu-100mm, Futhi i-axis ende ye-specimen ifana nendlela yokugoqa. Izinhlobo ze-Tensile zihlolwe emshinini wokuhlola we-KD II-1.

2 Imiphumela yokuhlola nokuhlaziywa
Ama-alloys amathathu anesakhiwo esifanayo futhi akukho devicessal sakhiwo enjengehlukaniso. Osayizi bokusanhlamvu balezi zinto ezintathu abuhlukile kakhulu, futhi usayizi wokusanhlamvu maqondana 150 μm, ehlangabezana nezidingo zenqubo yokugoqa okubandayo kanye nenqubo yokuvuselela ye-aluminium foil substrates.

Ukuze ufunde umphumela wokuqukethwe kwe-CU kwizakhiwo kanye nokumelana kokubhaka kwe-aluminium foil, izinhlobo ezintathu ze 8011 Imikhiqizo ye-Alloy Aluminium Foil enokuqukethwe okuhlukile kwe-CU kwahlolelwa izakhiwo zemishini nokusebenza kokuhlola kokubhaka kwemikhiqizo eqediwe. Ezintathu 8011 ama-alloys konke kuhlanganiswa okufanayo okubandayo, Ukuvela okuphakathi, futhi ukuzulazula kwe-foil kudlula ukuthola ama-foil aqediwe we-aluminium ubukhulu obufanayo. Amandla ashubile e-alloy akhombisa umkhuba owandayo ngokwanda kokuqukethwe kwe-CU. Ngemuva kokuhlolwa kokubhaka, amandla ashubile a 8011-3 I-Alloy enokuqukethwe okuphezulu kwe-CU yehle nge 24.1%, amandla ashubile a 8011-2 I-alloy yehle nge 30.9%, namandla ashubile a 8011-1 I-alloy yehle nge 33.3% . Kungabonakala lokho ngokwanda kokuqukethwe kwe-CU, ukuqina kokusebenza kwe-alloy ngemuva kokubhaka kuvame ukukhuphuka.

Ekuhlolweni kokubhaka, Kusukela ukumelana kokubhaka kwe-aluminium foil kuhlobene kakhulu nokuziphatha okuphindaphindeka kwe-alloy, Ukuze uqhathanise futhi utadishe indlela yokuhlaziya kabusha kwabathathu 8011 ama-alloys, ezintathu 8011 imikhiqizo eqediwe ye-alloy yafakwa ngaphansi 180 ℃, Anveling at 200 ℃ , 220 ℃ , 240 ℃ , 260 ℃ , 280 ℃ nge-3h, Imiphumela ikhombisa ukuthi ukuqina kokuvusa 8011-3 I-alloy iphakeme kunaleyo 8011-2 futhi 8011-1 ingxubevange, 8011 Ekushiseni okufanayo kokushisa nesikhathi. -3 Ama-alloys anokuphindaphinda kabusha kanye neziqu zokuthambisa.

Ngaphezu kwalokho, Siphinde saqhuba ukuhlolwa kwenani le-dyne kanye nokuhlolwa kwePinhole kwezintathu 8011 ama-alloys. Imiphumela yokuhlola ikhombisa ukuthi inani le-dyne nenombolo ye-pinhole yama-alloys amathathu ahlangabezana nezinga.

Okwe 8011 ingxubevange, ngaphakathi kwebanga elithile, ngokwanda kwe-Trace Alloying Element CU Okuqukethwe, Isixazululo esiqinile sokuqinisa umphumela sikhulu, Ngakho-ke amandla e 8011-3 Umkhiqizo oqediwe we-alloy uphakeme kunalokho kwe 8011-2 futhi 8011-1 ama-alloys.

I-CU ingakha inani elincane le-CUA12 Compound nge-Solid Solution Treapitation e-Aluminium Alloy. I-CUA12 Compound inesimo esingajwayelekile futhi esibushelelezi, futhi kusatshalaliswa ngaphakathi emngceleni wokusanhlamvu ngesimo samathambo, okudlala indima ekuhlukaniseni ukuphonswa kwe-aluminium foil elandelayo; Isizathu ukuthi i-CU ikakhulukazi ikhona ngendlela yesisombululo esiqinile ku-al, futhi kulula ukuqongelela ukuhlukaniswa. Ukwakheka kweCoriolis Air Mass kunciphisa ukuhlukaniswa kwe-lattice, Yehlisa ukusebenzisana kokunwebeka phakathi kwama-athomu we-solute, kwenza ukwakhekiswa esimweni esizinzile, Yehlisa inani lokuphambanisa okungahambi kahle, kuvimbela ukuphindaphinda kwe-dislocations, futhi kuvimbela ukuphindaphinda kwe-dislocations. I-Crystal nucletional ne-nucleation ikhule, Ngaleyo ndlela wandisa amandla we-alloy kanye nokushisa kabusha kokushisa kwe-aluminium foil eqediwe.

Okwesibili, Amanani we-TRACE wezinto ze-CU angaphinde akha izigaba zesibili, okuvimbela ukufuduka kwe-nuclei okuphindaphindwayo futhi kuvinjelwe ukukhula okusanhlamvu okuphindaphindwayo. Kafushane, ngaphakathi kwebanga elithile, Ukwandisa okuqukethwe kwe-Trace Alloying Element CU kungakhuphula izinga lokushisa kabusha kabusha kwe-alloy futhi kuthuthukise ukuqina kokushisa kwe-alloy. Kungabonakala ukuthi i-microalloying ingenye yezindlela ezibalulekile zokuthuthukisa ukumelana nokushisa kwama-alloys.

3 Ukugcina
1) Le khasi 8011-3 alloy futhi 8011-2 I-Alloy ngemuva kokukhulisa okuqukethwe kwe-CU ingahlangabezana nezidingo zamakhasimende ngokuya ngezezakhiwo zemishini eziqediwe, gyne surface, nenombolo yama-mainholes.
2) Ngokwanda kokuqukethwe kwe-CU, amandla ashubile a 8011 I-Alloy kancane iyanda; ngesikhathi esifanayo, Izinga lokushisa kabusha kabusha le-alloy libuye likhuphuke kancane kancane.
3) Ngemuva kokuhlolwa kokubhaka at 240 ℃ / 75s, amandla ashubile a 8011-3 I-Alloy enokuqukethwe okuphezulu kwe-CU yehle nge 24.1%, namandla ashubile a 8011-2 I-alloy yehle nge 30.9%; Amandla ashubile anciphile 33.3%. 8011-3 I-Alloy ikhombisa ukuhluka okuncane kwizakhiwo kune 8011-2 futhi 8011-1. Ukwandisa okuqukethwe kwe-CU kusiza ukuthuthukisa ukumelana kokubhaka kwe-aluminium foil eqediwe.
