Niobium Silicide, NbSi2

Niobium silicide composite binary alloy matrix composite ndeye inovimbisa yepamusoro-tembiricha chimiro chimiro. Mune ino miviri-chikamu chinoumbwa, mhinduro niobium inopa kutonhorera kwemukati mukamuri apo si2nb inopa yakasimba-tembiricha simba. Iyo inoumbwa ine yakakwira thermodynamic kugadzikana uye kugadzikana kweyakaomesesa patembiricha yakakwira.

1. Niobium silicide composite binary alloy matrix composite ndeye chivimbiso chepamusoro-tembiricha yechimiro. Mune ino mbiri-chikamu chinoumbwa, mhinduro niobium inopa kutonhorera kwemukati mukamuri apo si2nb inopa yakasimba-tembiricha simba. Iyo inoumbwa ine yakakwira thermodynamic kugadzikana uye kugadzikana kweyakaomesesa patembiricha yakakwira.
2. NbSi2 yakavakirwa superalloy ine yakanyanya kusungunuka poindi, yakaderera density uye yakanakisa yakazara zvivakwa. Iyo yekuvavarira sevhisi tembiricha iri 200-300 ℃ yakakwira kupfuura iyo yeNi yakavakirwa superalloy. Inotarisirwa kushandiswa mugesi turbine injini mashizha anoshanda pa1300-1500 ℃ uye anopisa magumo zvikamu zveaerospace mota scramjet injini.
3. Iyo yekutsvagisa nekusimudzira pfungwa yeNbSi2 yakavakirwa superalloy ndeyekuumba niobium based solid solution / Nb5Si3 hunyambiri chikamu chinoumbwa nekuwedzera ductile solid solution chikamu, icho chinogona kuvandudza mukamuri tembiricha kuomarara uku uchichengetedza yakanakisa yakakwira tembiricha simba.
