Niobium Silicide, NbSi2

ʻO ka Niobium silicide composite binary alloy matrix ahupapa kahi mea i kūkulu nui ʻia me ka wela. I loko o kēia hui pālua-pae, hāʻawi ka niobium solution i ka paʻakikī wela o ka lumi a hāʻawi ʻo si2nb i ka ikaika wela wela. Loaʻa ka paʻa thermodynamic kiʻekiʻe a me ka paʻa paʻa microstruktur i ka mahana wela.

1. ʻO Niobium silicide composite binary alloy matrix ahupapa kahi mea hoʻohiki kiʻekiʻe-wela. I loko o kēia hui pālua-pae, hāʻawi ka niobium solution i ka paʻakikī wela o ka lumi a hāʻawi ʻo si2nb i ka ikaika wela wela. Loaʻa ka paʻa thermodynamic kiʻekiʻe a me ka paʻa paʻa microstruktur i ka mahana wela.
2. NbSi2 ma muli o ka superalloy he kiko hoʻoheheʻe kiʻekiʻe, haʻahaʻa haʻahaʻa a me nā waiwai laulā maikaʻi. ʻO 200-300 ℃ ke kiʻekiʻe o kāna anahana lawelawe ma luna o ke kiʻekiʻe o Ni. Manaʻo ʻia e hoʻohana ʻia i nā pahi ʻenekini turbine e hana ana ma 1300-1500 ℃ a me nā ʻena hopena wela o ka engine scramjet engine aerospace.
3. ʻO ka manaʻo noiʻi a me ka hoʻomohala ʻana o ka superalloy NbSi2 i hoʻokumu ʻia e hana i ka niobium i hoʻokumu ʻia i ka hopena paʻa / Nb5Si3 pālua pae i hoʻohui ʻia e ka hoʻohui ʻana i ka ʻāpana hoʻonā paʻa paʻa ductile, hiki ke hoʻomaikaʻi i ka wela o ka wela o ka lumi me ka mālama ʻana i ka ikaika wela kiʻekiʻe.
