ʻO ka noi nui o High Entropy Alloys (HEAs)

ʻO nā Alloy Entropy kiʻekiʻe (HEAs) he mau mea metala kūikawā i haku ʻia me ʻelima a ʻoi aku paha nā mea metala. Ma muli o kona microstructure kū hoʻokahi a me nā waiwai maikaʻi loa, ua hoʻohana ʻia nā mea metala kiʻekiʻe entropy alloy i kekahi mau kahua. Aia nā noi nui:

Nā mea hoʻolālā kiʻekiʻe: ʻO nā mea metala kiʻekiʻe-entropy he paʻa paʻa kiʻekiʻe a me ke kūpaʻa wela kiʻekiʻe, a he kūpono ia no ka hana ʻana i nā ʻāpana hoʻolālā wela kiʻekiʻe ma ke kahua mokulele, e like me nā ʻāpana aerospace a me nā mea hoʻolālā spacecraft.

Nā mea kū'ē i ka corrosion: Loaʻa i nā mea metala kiʻekiʻe-entropy ke kūpaʻa maikaʻi loa a kūpono no ka hanaʻana i nā mea hana kemika, nā mea paipu, a me nā mea'ē aʻe i kaʻoihana kemika.

Biomedical kahua: No ka mea, he biocompatibility maikaʻi nā mea metala kiʻekiʻe-entropy, ua hoʻohana ʻia lākou ma ke kahua biomedical e hana i nā mea lapaʻau, e like me nā hui artificial, implantable stents, etc.

Ke kahua ikehu nuklea: Hiki ke hoʻohana ʻia nā mea metala kiʻekiʻe entropy i loko o ke kahua ikehu nuklea e hana i nā mea hoʻolālā nuklea.

Nā kahua ʻē aʻe: Hiki ke hoʻohana ʻia nā mea metala kiʻekiʻe entropy i ka ʻenekinia moana, ka hana kaʻa, ka hana mīkini a me nā kula ʻē aʻe.

Ma keʻano laulā, no ka mea he mau waiwai maikaʻi loa nā mea metala kiʻekiʻe entropy e like me ka ikaika kiʻekiʻe, ka pale ʻana i ka corrosion, a me ka pale ʻana i ke kapa, loaʻa iā lākou nā manaʻo noiʻi ākea ma nā ʻano he nui.
