Cov kev kho cua sov dab tsi muaj rau Qib 2 titanium forgings?
Qib 2 yog unalloyed (kev lag luam ntshiab) titanium, yog li nws tsis tuaj yeem ntxiv dag zog los ntawm kev kho cua sov zoo li nag lossis daus - hardening alloys. Nws muaj cov kev kho cua sov yog npaj rau kev ntxhov siab, softening, txhim kho ductility, los yog kho microstructure, es tsis muaj zog.
Lub ntsiab kev kho cua sov rau Qib 2 titanium forgings yog raws li nram no:
1. Kev ntxhov siab (feem ntau siv)
Qhov no yog kev kho cua sov tshaj plaws rau Qib 2 forgings tom qab forging lossis machining.
Lub Hom Phiaj: Txhawm rau tshem tawm cov kev ntxhov siab uas nyob hauv tau qhia thaum lub sijhawm forging, machining, sib sau, lossis vuam, txhawm rau txhim kho qhov ruaj khov thiab txo qhov kev pheej hmoo ntawm kev cuam tshuam lossis tawg hauv kev pabcuam.
Qhov kub thiab txias: 482-593℃(900-1100 ° F)
Cua txias: Feem ntau cua txias
Cov nyhuv: Tsis hloov pauv lub zog tensile lossis hardness; tuav zoo ductility thiab toughness.
2. Annealing (tag nrho annealing / recrystallization annealing)
Siv rau forgings uas yuav tsum tau siab tshaj plaws ductility, txhim kho formability, los yog uniform microstructure.
Lub hom phiaj: Ua kom tag nrho recrystallize lub microstructure, soften cov khoom, txo hardness, thiab txhim kho elongation thiab formability.
Qhov kub thiab txias: 704-760℃(1300-1400 ° F)
Tuav lub sij hawm: txaus los xyuas kom meej sib xws los ntawm -thickness cua sov
Cua Txias: Cua txias lossis cua sov cua txias
Cov nyhuv: Muab qhov zoo tshaj plaws ua ke ntawm ductility thiab toughness rau Qib 2 forgings.
3. Txheej txheem Annealing / Intermediate Annealing
Siv thaum lub sij hawm intermediate forming cov kauj ruam los kho formability.
Lub Hom Phiaj: Txhawm rau rov qab cov yas ntawm ntau qhov kev sib sau lossis kev ua haujlwm machining, tiv thaiv kev tawg thaum ua haujlwm txias.
Qhov kub thiab txias: Zoo ib yam li kev ntxhov siab los yog qis dua -kub annealing.
Ntsiab Lus
Qib 2 titanium tsis muaj kev laus, quenching, los yog nag lossis daus - kev kho cua sov, vim nws tsis dhau theem kev hloov pauv uas tso cai rau lub hnub nyoog hardening.
Kev kho cua sov yuav tsum tau ua nyob rau hauv qhov chaw tiv thaiv (nqus los yog inert gas) kom tiv thaiv oxidation, embrittlement, los yog hydrogen pickup.
Cov khoom siv kho tshuab ntawm Qib 2 forgings feem ntau yog tswj los ntawm cov tshuaj lom neeg muaj pes tsawg leeg (tshwj xeeb yog cov ntsiab lus sib txawv xws li O, N, H) thiab txheej txheem forging, tsis yog los ntawm kev kho cua sov.
Cov ntsiab lus
Rau Qib 2 titanium forgings, cov tswv yim thiab cov qauv kev kho cua sov yog:
Kev ntxhov siab
Tag nrho annealing (recrystallization annealing)
Intermediate txheej txheem annealing
Cov kev kho no txhim kho ductility, seem stability, thiab uniformity tsis muaj zog.
