Wahi a kahi hōʻike hou e ka Physicist Organization Network, ua noi nā ʻenekinia ma ke Kulanui o Kaleponi, Los Angeles, i nā nanoparticles titanium carbide e hana i ka alumini alumini kūikawā maʻamau AA7075, ʻaʻole hiki ke welded e lilo i welded.Manaʻo ʻia ka huahana e hoʻohana ʻia i ka hana kaʻa a me nā māla ʻē aʻe e hoʻomaʻamaʻa i kāna mau ʻāpana, ʻoi aku ka ikaika o ka ikehu, a paʻa mau.
ʻO ka ikaika maikaʻi loa o ka alumini alumini maʻamau ka 7075 alloy.Ua aneane like kona ikaika me ke kila, aka, he hapakolu wale no kona kaumaha o ke kila.Hoʻohana maʻamau ia i nā ʻāpana mīkini CNC, fuselage mokulele a me nā ʻēheu, nā pūpū atamai a me ka piʻi pōhaku carabiner, a me nā mea ʻē aʻe. .ʻO kēia no ka mea i ka wā e hoʻomehana ʻia ai ka alloy i ka wā o ke kaʻina hana kuʻi, ʻo kona ʻano molekala e hoʻoheheʻe ʻole ʻia nā mea hoʻohui i ka aluminika, zinc, magnesium a me ke keleawe, e hopena i nā māwae o ka huahana welded.

I kēia manawa, hoʻokomo nā mea ʻenekinia UCLA i nā nanoparticles titanium carbide i ka uea o AA7075, e ʻae ana i kēia mau nanoparticles e hana ma ke ʻano he mea hoʻopiha ma waena o nā mea hoʻohui.Ke hoʻohana nei i kēia ala hou, ʻo ka hui welded i hana ʻia he ikaika tensile a hiki i 392 MPa.ʻO ka hoʻohālikelike ʻana, ʻo ka AA6061 alumini alumini hui welded, i hoʻohana nui ʻia i nā mokulele a me nā ʻāpana kaʻa, loaʻa ka ikaika tensile o 186 MPa wale nō.

Wahi a ke aʻo ʻana, hiki i ka mālama wela ma hope o ke kuʻi ʻana ke hoʻonui i ka ikaika tensile o ka hui AA7075 i 551 MPa, i hoʻohālikelike ʻia me ke kila.Ua hōʻike pū ʻia nā noiʻi hou i hoʻopiha ʻia nā uea fillerTiC titanium carbide nanoparticleshiki ke hoʻohui maʻalahi i nā metala ʻē aʻe a me nā ʻāpana metala paʻakikī ke wili.

ʻO ka mea nui i mālama i ke aʻo ʻana: "Ua manaʻo ʻia ka ʻenehana hou e hana i kēia alumini alumini ikaika kiʻekiʻe i hoʻohana nui ʻia i nā huahana i hiki ke hana ʻia ma ke ʻano nui, e like me nā kaʻa a i nā kaʻa.Hiki i nā ʻoihana ke hoʻohana i nā kaʻina hana like a me nā lako i loaʻa iā lākou.Hoʻokomo ʻia kahi alloy alumini ikaika loa i loko o kāna kaʻina hana e hoʻomaʻamaʻa a ʻoi aku ka ikaika o ka ikehu ʻoiai e hoʻomau ana i kona ikaika. "Ua hana nā mea noiʻi me kahi mea hana kaʻa kaʻa no ka hoʻohana ʻana i kēia huila ma nā kino paikikala.
