6Al-4V ELI
Apr 16, 2020
Tsawg interstitial version of Ti-6Al-4V, rau qhov siab tshaj plaws. Txheeb rau cov ntawv thov marine thiab cryogenic. Qib no nquag siv nyob rau hauv annealed mob. Ti-6Al-4V yog qhov kev xaiv zoo tshaj plaws rau daim teb cog hniav kho mob.
Kev nyuab siab nyem 900-1200 ° F 1 txog 4 teev, cua txias. Dune anneal, bar thiab qhov zam: Cov tshuaj anneal 50-100 ° F hauv qab qhov beta transus, tuav 1 teev tsawg kawg, cua txias. Tom qab ntawd rov rhaub dua li ntawm 1300-1400 ° F, tuav 1 teev tsawg kawg, cua txias. Kev ntxhov siab - nyem annealing yog ua tom qab vuam.
