Kwicandelo lokuvelisa nobunjineli obuchanekileyo obuphezulu, ii-alloys ze-aluminium ziye zaba zizixhobo zokwakha ezingenakutshintshwa ngenxa yeempawu zazo ezilula nezinamandla aphezulu. Phakathi kwazo,Ibha ye-aluminiyam eyenziwe nge-7075 T652Ivelele njengemveliso ye-aluminium alloy enamandla aphezulu, eyinxalenye yoluhlu lwe-Al-Zn-Mg-Cu lwee-aluminium alloys ezinamandla aphezulu. Iyaziwa kakhulu kwi-aerospace, kwizixhobo zomkhosi, koomatshini abachanekileyo nakwamanye amashishini afunwa kakhulu ngenxa yeempawu zayo ezibalaseleyo zoomatshini kunye nozinzo olunemilinganiselo.
Ukwakheka kweekhemikhali ze-7075 T652 Forged Aluminium Bar
Ukusebenza okuphezulu kwe-7075 T652 forged aluminium bar kuxhomekeke ngokusisiseko kumlinganiselo wayo ochanekileyo wekhemikhali, ohambelana ngokungqongqo nemigangatho yamazwe ngamazwe efana ne-ASTM B247, i-AMS 4140 kunye ne-QQ-A-250/24. Izinto eziphambili zekhemikhali (inxalenye yobunzima) zezi zilandelayo:
I-Aluminiyam (Al) imalunga ne-90.7% ~ 94.7%, isebenza njenge-matrix element ukuqinisekisa ukuxhathisa okusisiseko kokukhanya kunye nokugqwala kwe-alloy.
I-Zinc (Zn) yeyona nto iphambili yokuqinisa, enomxholo we-5.1% ~ 6.1%, eyenza i-intermetallic compound enamandla aphezulu ene-magnesium kunye ne-copper ukuphucula kakhulu amandla okuxinana kunye nobunzima be-alloy.
Umxholo weMagnesium (Mg) yi-2.1% ~ 2.9%, isebenzisana ne-zinc ukuphucula isiphumo sokuqina kwemvula kunye nokunyusa amandla okuvelisa i-alloy.
Umxholo weCopper (Cu) yi-1.2% ~ 2.0%, nto leyo eyenza ukuba i-alloy ibe namandla kwaye iqine, ngelixa iphucula ukumelana kwayo nokugqwala ngenxa yoxinzelelo.
Ukongeza, izixa ezincinci zeChromium (Cr 0.18% ~ 0.28%) zongezwa ukuze kucocwe ulwakhiwo lwengqolowa, kususwe iziphene zangaphakathi, kwaye kuphuculwe ukumelana nokudinwa kwe-alloy, ngolawulo oluqinileyo lwezinto ezingcolisayo ezifana nentsimbi kunye ne-silicon ukuqinisekisa ubunyulu kunye nokuzinza kokusebenza kwebhari eyenziweyo.
Le bha ye-aluminium ehambelana ngokuchanekileyo ne-7075 T652 eyenziwe nge-aluminium enesiseko esiqinileyo, ithintela iziphene zokusebenza ezibangelwa ngumxholo we-element ogqithisileyo okanye onganeleyo, kwaye ibeka isiseko esiqinileyo seempawu zayo ezibalaseleyo zoomatshini kunye nokusebenza kwayo.
Iimpawu zokusebenza eziphambili ze-7075 T652 Forged Aluminium Bar
Ibha ye-aluminium eyenziwe ngomgunyathi ye-7075 T652 icutshungulwa ngokubumba ngokuchanekileyo, unyango lobushushu olunesisombululo, uxinzelelo lokunciphisa uxinzelelo kunye nokuguga okwenziweyo (ubushushu be-T652), nto leyo edibanisa ngokugqibeleleyo iingenelo zokubumba kunye nonyango lobushushu, ebonisa iseti yezalathisi zokusebenza ezigqwesileyo ezihlangabezana neemfuno zokwenziwa okuphezulu.
Ngokweempawu zoomatshini, inamandla okutsalwa kunye namandla okukhupha inkunkuma ephezulu kakhulu, inamandla okutsalwa ukuya kuthi ga kwi-570 ~ 590 MPa kunye namandla okukhupha inkunkuma angama-475 ~ 505 MPa, athelekiswa nentsimbi yekhabhoni ephakathi kwisinye kwisithathu soxinano lwentsimbi, ifikelela kwibhalansi efanelekileyo phakathi komthamo olula kunye nowokuthwala umthwalo. Ubunzima bayo beBrinell bufikelela kwi-150 ~ 160 HB, bunokumelana okuhle kokuguguleka kunye nokukwazi ukulwa nokuguquka, bufanelekile ukuvelisa izinto ezinomthwalo ophezulu. Okwangoku, i-T652 temperature isebenzisa ukukhululeka koxinzelelo lokucinezelwa kwe-1% - 5% emva konyango lwesisombululo, isusa ngokupheleleyo uxinzelelo lwangaphakathi oluvela kwinkqubo yokwenziwa kunye nonyango lobushushu, iqinisekisa uzinzo oluhle kakhulu ngexesha lokwenziwa kunye nokusetyenziswa kwexesha elide, iphephe ukugoba, ukuguqulwa kunye nokuphambuka kobungakanani, okubaluleke kakhulu kwiindawo zokwenziwa ngokuchanekileyo.
Ngokuphathelele ukulungelelana nokusingqongileyo, inamandla okudinwa kunye nokuqina kwempembelelo, iyakwazi ukumelana nemithwalo ephindaphindwayo etshintshanayo kunye nempembelelo ekhawulezileyo ngaphandle kokuqhekeka, ifanelekile kwinkonzo yexesha elide kwiimeko zokusebenza ezinzima. Nangona ukumelana kwayo nokugqwala kubuthathaka kunokwe-5000 series aluminium alloys, unyango olufanelekileyo lomphezulu olufana ne-anodizing kunye ne-coating lunokuphucula ngempumelelo ukumelana kwayo nokugqwala, lwandise ububanzi bokusetyenziswa kwayo. Ikwanayo nokusebenza kakuhle kwe-machinability, inokukwazi ukuzivumelanisa nokujika, ukugaya, ukubhola kunye nezinye iinkqubo zokugaya ngokuchanekileyo, kwaye kulula ukwenza iindawo ezintsonkothileyo zesakhiwo, ukuhlangabezana neemfuno zokucubungula ngokuchanekileyo kwezixhobo eziphezulu.
