Lub plasticity ntawm tungsten alloy yog hais txog cov cuab yeej uas ib qho khoom raug rau lub zog tshaj nws cov elastic txwv, uas qhia tas li thiab mus tas li deformation. Nws hais txog lub peev xwm ntawm cov khoom siv los tiv thaiv cov yas deformation yam tsis muaj kev tawg. Nws feem ntau yog ntsuas los ntawm universal tensile lub zog kuaj tshuab. Lub tshuab ntsuas tensile yog lub cim tshiab ntawm cov cuab yeej ntsuas kev sib xyaw ua ke nrog kev tswj hwm lub computer, kev ntsuas tsis siv neeg, kev tau txais cov ntaub ntawv, tshuaj ntsuam xyuas, thiab kev sim ua tiav. Nws siv lub tshuab ua haujlwm nyob rau hauv lub tog raj kheej roj raws li lub platform, thiab tau nruab nrog cov twj tso kua mis precision, electro-hydraulic servo li qub, thiab PC servos. tus tswj.
Lub plasticity ntawm tungsten alloy tsis tas li thiab yuav cuam tshuam los ntawm ntau yam, xws li cov khoom muaj pes tsawg leeg, raw khoom piv, microstructure, txheej txheem tsis, post-processing thiab ua hauj lwm ib puag ncig, thiab lwm yam txo ntawm cheeb tsam, qhov zoo dua cov plasticity ntawm cov khoom siv alloy; conversely, qhov me me qhov elongation los yog qhov txo qis ntawm cheeb tsam, qhov ua rau cov plasticity ntawm cov khoom siv hlau tsis zoo.
1. Cov khoom muaj pes tsawg leeg
Cov muaj pes tsawg leeg ntawm tungsten-raws li alloys muaj xws li nyuaj theem tungsten, binder theem nickel, hlau los yog tooj liab, thiab lwm yam. Thaum lub binder theem sib txawv, lub plasticity Performance index ntawm tungsten-raws li alloy kuj txawv. Cov kev tshawb fawb tau pom tias qhov elongation ntawm 90W7Ni3Fe yog 18 feem pua -29 feem pua, thiab elongation ntawm 90W6Ni4Cu yog li 6 feem pua.
2. Raw khoom piv
Thaum cov khoom muaj pes tsawg leeg thiab daim ntawv thov yog tib yam, thiab qhov piv ntawm raw cov ntaub ntawv nyob rau hauv ib tug tej yam ntau yam, ntau dua cov binder theem cov ntsiab lus los yog cov ntsiab lus tungsten tsawg, qhov zoo dua cov plasticity ntawm tungsten alloy; Ntawm qhov tsis sib xws, qhov tsawg dua cov ntsiab lus binder theem lossis siab dua cov ntsiab lus tungsten, Lub plasticity ntawm tungsten alloy yog qhov phem dua. Cov kev tshawb fawb tau pom tias qhov elongation tus nqi ntawm 90W7Ni3Fe yog 18 feem pua -29 feem pua, ntawm 91W6Ni3Fe yog 17 feem pua -27 feem pua, ntawm 92W5Ni3Fe yog 16 feem pua -26 feem pua, ntawm 93W4Ni3Fe yog 1. feem pua -24 feem pua , thiab ntawm 95W3Ni2Fe yog 10 feem pua -22 feem pua . 97W2Ni1Fe yog 6 feem pua -13 feem pua .
3. Microstructure
Nyob rau hauv cov ntaub ntawv ntawm tib cov ntaub ntawv muaj pes tsawg leeg thiab lwm yam, lub finer lub tungsten hais, qhov ntau uniform lub particle loj tis, thiab ntau uniform lub binder theem faib, qhov zoo dua lub plasticity ntawm tungsten-raws li alloy.
4. txheej txheem tsis
Cov txheej txheem ntau lawm ntawm tungsten alloy feem ntau suav nrog hmoov metallurgy thiab txhaj tshuaj molding tshuab. Ntawm lawv, cov txheej txheem ntawm cov hmoov metallurgy txheej txheem yog: sib tov → nias → pre-firing → kua theem sintering → tshav kub kev kho mob → blank cutting → txias ua → cov nyhuv → kawg txiav → tiav cov khoom. Cov txheej txheem ntawm kev txhaj tshuaj molding tshuab yog: sib xyaw pub → granulation → txhaj tshuaj → degreasing thiab pre-sintering → sintering → kho cua sov → khoom tiav.
Txawm li cas los xij, nyob rau hauv ob qho tib si txheej txheem, sintering kub muaj qhov cuam tshuam zoo rau cov yas ntawm tungsten alloy. Nws cov plasticity yuav ua ntej nce thiab tom qab ntawd txo nrog qhov nce ntawm sintering kub.
5. Tom qab ua tiav
Lub plasticity ntawm tom qab kho tungsten alloy yog qhov zoo dua. Tom qab kev kho mob feem ntau suav nrog kev kho cua sov thiab deformation ntxiv dag zog. Ntawm lawv, txoj kev kho cua sov feem ntau suav nrog kev kho quenching, lub tshuab nqus tsev lossis inert cua dehydrogenation kev kho mob, kev kho cua sov cyclic, thiab lwm yam.; Lub zog deformation feem ntau suav nrog forging, kub extrusion, kub dov thiab forging puas deformation txheej txheem.
