1. VSRIGATORN MEFRATOR (VSR): Tsis -} Thermal, Kev Nyuaj Siab Txo
Cov ntsiab lus:
Rhais Electromagnetic lossis tshuab Vibrators rau welded tivthaiv, ces qhib lub coctration zaus kom phim cov khoom siv ntuj resonance (feem ntau 10-200 hz).
Khiav qhov kev co rau 30-120 feeb, nyob ntawm feem me me. Cov resonance ua rau sab hauv kev ntxhov siab los them cov mob tsis haum hauv cov hlau lub tshuab ua kom muaj kev ntxhov siab.
Hauj tes: Txo cov kev ntxhov siab ntawm30–50%(piv rau 60-80% nrog anealing). Nws tsis cuam tshuam SMA570w kev ua yeeb yaj kiab huab cua, vim tsis muaj cua sov yog siv los hloov kev xa cov khoom xa tawm.
Kev siv tau: Qhov zoo tagnrho rau cov khoom me me / xws li, nyias {{} {} Cov txheej txheem thauj mus rau annealing cov chaw yog tsis yooj yim. Nws tseem yuav zam cov thermal distortion - tseem ceeb rau cov khoom siv nrog kev ncua ntev.
2. Tsawg {{{{}} kub tempering: protually Thermal Nyem
Cov ntsiab lus:
Ua kom sov lub welded tivthaiv rau qhov kub ntawm180-220 degree(Nyob rau hauv qab no 550-600℃ntau rau annealing) thiab tuav tau 2-4 teev.
Txias cov tivthaiv maj mam nyob rau hauv huab cua (tsis muaj nruj tswj kev tswj hwm xav tau, tsis zoo li anealing).
Hauj tes: Txo cov kev ntxhov siab ntawm20–35%Thiab feem ntau yog txhim kho kev kub taub hau los ntawm kev kho me me, brittle Micructures (piv txwv li, martensite) tsim thaum lub sij hawm vuam. Nws tsis soften lub hauv paus cov hlau lossis dilute cov tshuaj tiv thaiv (Cu, CR), yog li patina tsim tsis muaj kev cuam tshuam.
Kev siv tau: Zoo tshaj plaws rau nyias daim hlau (<20mm) or components used in cold environments (below 0°C), where maintaining low-temperature toughness is critical. It is also used to "touch up" stress relief after VSR, further reducing remaining stress.
3. Tua Cov Peening: Kev Hloov Kev Nyab Xeeb Kev Nyab Xeeb
Cov ntsiab lus:
Blast lub weld nto thiab haz nrog me me, siab} Kev txhaj tshuaj steel lossis 0.21 hli hauv lub siab) ntawm lub siab ntawm 0.2-0.6 mpa.
Qhov cuam tshuam ntawm kev txhaj tshuaj tsim cov khoom me me ntawm cov npoo av, hloov tensile seem kev ntxhov siab (uas txhawb nqa kev tawg thiab corrosion.
Hauj tes: Tsom rauNto thiab ze - kev ntxhov siab saum npoo av(txog 0.5 hli tob), txo cov kev ntxhov siab no los ntawm40–60%Cov. Kev ntxhov siab txheej txheem txheej txheem txheej txheem ntawm kev pib ntawm txoj kev xeb pits, indirectly txhawb nqa Patina Stability.
Kev siv tau: Siv los ua cov txheej txheem ntxiv rau cov ntaub ntawv pov thawj kev sib tw (piv txwv li, pob qij txha) lossis chaw hnyav (piv txwv li thaj chaw ntug dej hiav txwv). Nws tsis tuaj yeem hloov cov annaling rau cov tuab (qhov twg sab hauv kev ntxhov siab ua rau muaj kev ntxhov siab ntxiv
