I-Tungsten Alloy luhlobo lwe-alloy material kunye ne-transition metal tungsten (W) njengesigaba esinzima kunye ne-nickel (Ni), isinyithi (Fe), ubhedu (Cu) kunye nezinye izinto zetsimbi njengesigaba sokudibanisa. Ineepropati ezintle kakhulu ze-thermodynamic, iikhemikhali kunye nombane kwaye isetyenziswa ngokubanzi kukhuselo lwelizwe, umkhosi, i-aerospace, i-aviation, i-automotive, unyango, i-electronics yabathengi kunye nezinye iinkalo. Iimpawu ezisisiseko ze-tungsten alloys zifakwe ikakhulu ngezantsi.
1. Ukuxinana okuphezulu
Uxinaniso bubunzima kwiyunithi nganye yomthamo wento kunye nophawu lwento. Inxulumene kuphela nohlobo lwento kwaye ayinanto yakwenza nobunzima bayo kunye nomthamo. Ubuninzi be-tungsten alloy ngokuqhelekileyo yi-16.5 ~ 19.0g / cm3, ephindwe kabini ukuxinwa kwentsimbi. Ngokuqhelekileyo, ukuphakama komxholo we-tungsten okanye ungaphantsi komxholo wensimbi edibeneyo, ukuphakama kobuninzi be-tungsten alloy; Ngokuchasene noko, ubuninzi be-alloy buphantsi. Ubuninzi be-90W7Ni3Fe bumalunga ne-17.1g/cm3, leyo ye-93W4Ni3Fe imalunga ne-17.60g/cm3, kwaye leyo ye-97W2Ni1Fe imalunga ne-18.50g/cm3.
2. Indawo ephezulu yokunyibilika
Indawo yokunyibilika ibhekisa kwiqondo lobushushu apho into iguqukayo ukusuka kokuqinileyo ukuya kulwelo phantsi koxinzelelo oluthile. Indawo yokunyibilika ye-tungsten alloy iphezulu, malunga ne-3400 ℃. Oku kuthetha ukuba i-alloy material inokumelana nokushisa okulungileyo kwaye akulula ukuyinyibilika.
3. Ubunzima obuphezulu
Ukuqina kubhekiselele kwisakhono sezinto zokumelana ne-indentation deformation ebangelwa zezinye izinto ezinzima, kwaye yenye yezibonakaliso ezibalulekileyo zokuxhathisa ukunxiba. Ukuqina kwe-tungsten alloy ngokuqhelekileyo yi-24 ~ 35HRC. Ngokubanzi, okukhona uphezulu umxholo we-tungsten okanye usezantsi umxholo wesinyithi obophelelayo, kokukhona ukuqina kwe-tungsten alloy kunye nokuba ngcono ukuxhathisa ukunxiba; Ngokuchasene noko, ubuncinci ubunzima be-alloy, ngakumbi ukuchasana kokugqoka. Ubunzima be-90W7Ni3Fe yi-24-28HRC, leyo ye-93W4Ni3Fe yi-26-30HRC, kwaye leyo ye-97W2Ni1Fe yi-28-36HRC.
4. I-ductility elungileyo
I-Ductility ibhekiselele kwisakhono seplastiki sokuguqula izinto ngaphambi kokuqhekeka ngenxa yoxinzelelo. Kukukwazi kwezixhobo zokuphendula kuxinzelelo kunye nokukhubazeka ngokusisigxina. Ichatshazelwa zizinto ezifana nomlinganiselo wezinto ezikrwada kunye neteknoloji yokuvelisa. Ngokuqhelekileyo, okukhona kuphezulu isiqulatho se-tungsten okanye ukuthoba isiqulatho sesinyithi esidityanisiweyo, kokukhona kuncinci ukwandiswa kweealloyi ze-tungsten; Ngokuchasene noko, ukunyuka kwe-alloy kuyanda. Ubude be-90W7Ni3Fe yi-18-29%, leyo ye-93W4Ni3Fe yi-16-24%, kwaye leyo ye-97W2Ni1Fe yi-6-13%.
5. Amandla aphezulu okuqina
Amandla e-tensile lixabiso elibalulekileyo lotshintsho ukusuka kwi-deformation yeplastiki efanayo ukuya kwi-deformation yeplastiki egxininiswe yendawo yezixhobo, kunye nobukhulu bomthamo wezinto eziphathekayo phantsi kweemeko zokuxinana kwe-static. Inxulumene nokwakhiwa kwezinto, umlinganiselo wezinto eziluhlaza kunye nezinye izinto. Ngokubanzi, amandla okuqina e-tungsten alloys ayanda ngokunyuka komxholo we-tungsten. Amandla e-tensile ye-90W7Ni3Fe yi-900-1000MPa, kwaye leyo ye-95W3Ni2Fe yi-20-1100MPa;
6. Ukusebenza kakuhle kokukhusela
Ukusebenza kokukhusela kubhekiselele kwisakhono semathiriyeli ukuvala imitha. I-Tungsten alloy inomsebenzi obalaseleyo wokukhusela ngenxa yobuninzi bayo. Ubuninzi be-tungsten alloy yi-60% ephezulu kuneyelothe (~ 11.34g / cm3).
Ukongeza, i-alloys ye-tungsten ephezulu yoxinaniso ayinayo ityhefu, ihambelana nokusingqongileyo, ayinayo i-radioactive, i-coefficient yokwandisa i-thermal ephantsi kunye nokuhanjiswa kakuhle.
