Titanium: ib qho khoom siv tseem ceeb rau riam phom



Titanium alloy tau siv dav hauv kev lag luam riam phom thiab tau dhau los ua cov khoom siv tsis tau. Nrog titanium, riam phom tau dhau los ua muaj zog thiab muaj zog dua. Titanium alloy riam phom tsis tsuas yog lub teeb ntawm qhov hnyav, zoo maneuverability, tab sis kuj muaj zog ntxiv. Lawv tshwj xeeb tshaj yog haum rau cov tub rog hauv huab cua thiab cov tub rog tawm tsam. Titanium alloy mortar lub rooj phaj yog ntau tshaj 50 feem pua ​​​​sib dua li cov hlau phaj. Titanium alloys yog siv los ua mortar raj, lub rooj zaum, High- cov ntaub ntawv zoo xws li cov thoob thiab cov phom mounts kuj yog cov ntaub ntawv zoo los npaj cov khaub ncaws tiv thaiv thiab kaus mom hlau.


Txij li thaum muaj kev tsim khoom ntawm titanium thiab titanium alloys nyob rau hauv nruab nrab -1940s, Tebchaws Asmeskas thiab Soviet Union tau pib mob siab rau thiab kawm txog lawv cov kev siv riam phom. Watertown Ordnance Factory ntawm Tebchaws Meskas tau ua ntau yam kev txhim kho hauv kev siv cov titanium alloys hauv riam phom. Kev sib deev ua haujlwm yog qhov loj tshaj plaws thiab qib siab tshaj plaws hauv lub ntiaj teb los kawm txog kev siv cov titanium alloys hauv kev ua riam phom. Xyoo 1955, Asmeskas kev lag luam riam phom siv 57 tons ntawm titanium, 281 tons hauv xyoo 1961, thiab 1,040 tons hauv xyoo 1971. Nws kwv yees tias nws yuav ncav cuag 2,100 tons hauv 2020. Vim tias nws yog lub sijhawm tsis ua tsov rog, qhov kev loj hlob tsis yog. ceev ceev.

Kev siv hauv artillery

Titanium thiab titanium alloys yog cov ntaub ntawv tseem ceeb rau kev tsim cov khoom siv phom loj. Txij li thaum xyoo 1950, lawv tau siv hauv qee lub ntiaj teb- cov phom loj loj. Lub chim, chamber, nozzle thiab tso tawm piston ntawm M28 120mm Crockett recoilless phom tsim nyob rau hauv Tebchaws Meskas xyoo 1950 yog forged thiab extruded nrog Ti-6Al-6V-2Sn-0.5Fe-0.5Cu alloy Qhov hnyav ntawm tag nrho cov phom yog 68kg, uas yog 34.9 feem pua ​​​​tshaj dua 104.4kg ntawm cov phom hlau. Tom qab sib cais, 5 tus neeg tuaj yeem nqa tau yooj yim rov qab. Xyoo 1961, kev tsim khoom loj tau pib, nruab nrog cov tub rog tub rog, tub rog tub rog, tub rog tub rog tub rog, tub rog tub rog, tank battalion thiab kev faib dav hlau muaj qhov zoo ntawm qhov me me, lub cev nyhav, lub zog loj, siab maneuverability thiab yooj yim camouflage. TI-6Al-6V-2Sn-0.5Fe-0.5Cu yog (ntxiv) hom alloy. Cov khoom ntawm lub xeev annealed yog: tensile zog 1098MPa, yield zog 1030MPa, elongation 13 feem pua, thiab seem shrinkage tus nqi 37 feem pua, Brinell hardness 34.


In the 1970s, Ti-6Al-4V-2Sn titanium alloy was used to make barrels, and Ti-6Al-4V, Ti-7Al-4Mo and Ti-5Al-1.5Fe-1.4Cr-1.2Mo titanium alloys were used to make the gun barrel. , Nozzle and launch piston, the mass of the whole gun is only 49kg, 4 people can resist running forward. After the T66 type 76mm gun's tailstock and gun mount were changed to titanium alloy, it was 93.55kg lighter than steel, only 142.9kg. The titanium alloy frame of the wild cannon is 42 percent lighter than steel. Later, the United States used industrial pure titanium to manufacture the seat plate of the T227 81mm mortar, which was 50 percent lighter than the steel plate, only 10.9kg. The plug of the gun is also made of titanium alloy, which is used to connect the barrel and the seat plate. Hundreds of test shots have been carried out on the ground and on the gravel ground, and good results have been achieved. After the T227 type 81mm mortar was replaced with a titanium seat plate, the mass dropped to 34kg and the range increased to 4500m, while the steel gun had a mass of 42.25kg and a range of 3600m. Not only was the mass reduced by 20 percent , the range was increased, and it was more maneuverable. To improve.


After Japan's 155mm chase mount plate was replaced with Kobe Steel's titanium alloy, the quality was reduced by about 50 percent . The 5mm and 8mm Ti-6Al-4V alloy plates were used for welding. Tests showed that the welding quality is good and can fully meet the combat needs. . The 100mm mortar seat plate made of TA7 alloy in Japan is 10kg lighter than the steel plate. It was designed and finalized in 1981 and produced and installed in 1983. The body, base and bracket of the 82mm mortar installed in 1984 were changed to titanium alloy, which was 16.6kg lighter than steel.


On January 31, 2007, the US "Army Times" stated that the 155mm M777 new type howitzer is the first ground combat system made of titanium alloy, which is about 3150kg lighter than the obsolete M198 type artillery, and its mass is reduced by nearly 50 percent . The decline in the quality of the artillery system has not affected its range and accuracy, but its mobility has been greatly improved.

Cov kaus mom hlau, lub cev armor thiab lwm yam khoom siv

Los ntawm 1959 txog 1961, Tebchaws Meskas tau siv Ti-6Al-4V thiab Ti-5Al-2.5Sn titanium alloys los tig M-1 tus qauv kaus mom hlau tsis muaj kev vam meej. Tom qab ntawd, lawv hloov mus rau Ti-4Al-3Mn titanium alloys thiab tawg ua txheej txheem. Qhov hnyav tsuas yog {{10}}.794kg-1.02kg. Nyob rau hauv cov nqe lus ntawm cov mos txwv phom, lub kaus mom hlau titanium yog tib yam li lub kaus mom hlau, tab sis lub kaus mom hlau titanium yog 0.45kg sib zog dua li tus qauv hlau kaus mom hlau.


Tebchaws Asmeskas siv cov ntawv tuab 25.4 hli uas muaj 10 txheej nylon thiab 1 txheej ntawm Ti-5Al-2.5Sn titanium alloy daim ntawv los tsim cov tsho tiv thaiv mos txwv. Nws qhov hnyav tsuas yog 3.86kg. Nws tuaj yeem tiv taus cov plhaub, grenades, thiab kuv cov khoom tawg, tab sis tsis yog 7.62 hli. mos txwv.


Lub muzzle nres ntawm Lavxias teb sab Union 152 hli ob - rab phom tus kheej - phom yog ua los ntawm titanium alloy. Nws muaj ob lub thoob, uas yog siv sib hloov thaum tso tawm. Lub tso tawm nrawm nrawm thiab lub zog hluav taws xob muaj zog, ncav cuag 15-18 puag ncig ib feeb; nws yog hloov tau thiab muaj peev xwm off-txoj kev. Muaj zog, thiab muaj zog muaj sia nyob.


Tuam Tshoj tau kawm txog daim ntawv thov ntawm titanium alloys hauv kev tsim riam phom txij li xyoo 1970, nrog cov txiaj ntsig zoo kawg li. Lub anti- tank missile steering iav thiab ncej yog ua los ntawm TC9 titanium alloy, uas yog Ti-0.2Pd alloy, uas yog siv nyob rau hauv lub xeev annealed; 85 hom anti- dav hlau tshuab rab phom nres ua los ntawm TC4 titanium alloy tau ua tiav cov txiaj ntsig zoo Tom qab, kev siv precision casting ZTC4 alloy los hloov TC4 alloy extruded tuav tau ua tiav cov txiaj ntsig zoo, thiab cov khoom siv tau nce los ntawm 18 feem pua ​​​​rau 94 feem pua ​​​​, thiab nws tseem txuag tau ntau ntawm cov nqi txiav, tua ob tug noog nrog ib lub pob zeb. TC4 yog feem ntau siv Ti-6Al-4V alloy nrog cov khoom zoo, ntxiv rau hom, siv hauv lub xeev annealed. Lub teeb flamethrower ua los ntawm titanium muaj qhov ntev txog li 70m. Nws yog ib qho riam phom ze ze, uas yog ntau tshaj 3kg sib dua li ua los ntawm cov hlau. Nws tuaj yeem ua los ntawm kev lag luam ntshiab titanium, Ti-3Al-2.5V thiab lwm yam alloys.
