Niobium Silicide, NbSi2

Niobium silicide composite binary alloy matrix puas yog qhov ua tau zoo siab cov khoom kub ua haujlwm. Hauv ob qib ua ke no, kev daws teeb meem niobium muab chav kub ua kom nruj thaum si2nb muab kev ua haujlwm ntawm siab kub. Cov khoom ua ke muaj qhov siab thermodynamic ruaj khov thiab microstructural stability ntawm qhov kub.

1. Niobium silicide composite binary alloy matrix puas yog qhov ua tau zoo siab cov khoom nruab nrab siab. Hauv ob qib ua ke no, kev daws teeb meem niobium muab chav kub ua kom nruj thaum si2nb muab kev ua haujlwm ntawm siab kub. Cov khoom ua ke muaj qhov siab thermodynamic ruaj khov thiab microstructural stability ntawm qhov kub.
2. NbSi2 based superalloy muaj qhov chaw siab melting, qhov ntom ntom thiab cov khoom zoo heev. Nws lub hom phiaj pabcuam kub yog 200-300 ℃ siab dua li ntawm Ni based superalloy. Nws xav kom siv rau hauv cov roj av rau lub cav ntsaws lub ntsej muag ua haujlwm ntawm 1300-1500 ℃ thiab kub kawg Cheebtsam ntawm aerospace tsheb scramjet cav.
3. Lub tswv yim tshawb nrhiav thiab kev tsim kho ntawm NbSi2 raws superalloy yog tsim niobium raws li cov khoom siv ruaj khov / Nb5Si3 dual theem sib ntxiv los ntawm kev ntxiv cov kua roj ua kua theem, uas tuaj yeem txhim kho chav kub kom nruj thaum tswj lub zog kub zoo.
