Explosively Formed Projectile (EFP) yog lub cev muaj zog nkag mus rau hauv lub cev thaum lub cev zoo li tus nqi nrog cov tshuaj hauv qhov dej ntiav ntiav tawg. Nws yog ib ceg ntawm kev siv thev naus laus zis thiab feem ntau yog siv los tiv thaiv lub tank Artillery shells, missiles, aerial foob pob, mines thiab davhlau ya nyob twg rhiab mos txwv, thiab lwm yam.
Raws li ib qho ntawm cov khoom tseem ceeb ntawm EFP, ntxiv rau tooj liab, hlau ntshiab, ntshiab nickel lossis ntshiab tungsten cov ntaub ntawv, lub liner tuaj yeem ua los ntawm tantalum-tungsten (TaW) alloy, tungsten-copper (WCu) alloy thiab tungsten-tungsten-tungsten-nickel. hlau alloy. (WCuNi) alloy thiab lwm yam khoom siv los tsim. Ntawm lawv, cov tshuaj-hom daim npog qhov ncauj ua los ntawm tantalum-tungsten alloy muaj kev nkag tau zoo dua, nrog rau kev muaj peev xwm nkag mus thiab qhov tob tob, uas yog vim qhov ceev dua thiab zoo dua ductility ntawm TaW alloy.
Raws li kev tsim qauv sib txawv, tantalum-tungsten alloy liner tuaj yeem muab faib ua thawj nkhaus liner, quadratic kab liner thiab ntau txoj kab nkhaus, thiab lwm yam. npog thiab tswb-puab npog; nkhaus). Txawm hais tias hom tshuaj zoo li lub hau npog, lawv cov phab ntsa npog tuaj yeem sib npaug ntawm phab ntsa tuab lossis cov phab ntsa sib txawv, thiab lub khob hliav qab feem ntau yog 120 degree -150 degree .
Cov kauj ruam ntau lawm ntawm tantalum-tungsten alloy liner: ua ntej, cov hmoov metallurgy txoj kev (hmoov sib tov → isostatic nias → nqus tsev kub kub sintering) yog siv los ua cov hlau alloy; ces lub ingot yog tau los ntawm ob electron beam melting; thiab tom qab ntawd qhov loj deformation Calorimetry forging lub billet kom tau lub forged pas nrig dawb paug, thiab tom qab ntawd lub tshuab nqus tsev annealing tshav kub kho kom zoo dua cov nplej, thiab tom qab ntawd forging ua kom lub ntsej muag tshuaj dawb paug, ua raws li recrystallization annealing tshav kub kho kom tau cov tshuaj daim npog qhov ncauj; Thaum kawg siv lub tshuab dhos CNC los ua kom cov tshuaj npog ntsej muag dawb huv tiav rau hauv cov tshuaj zoo li cov khoom siv.
