Ngokombiko wakamuva we-Physicist Organisation Network, onjiniyela baseNyuvesi yaseCalifornia, eLos Angeles, basebenzise i-titanium carbide nanoparticles ukuze benze ingxubevange evamile ye-aluminium ekhethekile i-AA7075, engakwazi ukushiselwa ukuba ishiselwe. Umkhiqizo ovelayo kulindeleke ukuthi usetshenziselwe ukukhiqiza izimoto nakweminye imikhakha ukuze wenze izingxenye zawo zibe lula, zisebenzise amandla kakhudlwana, futhi zihlale ziqinile.
Amandla angcono kakhulu engxubevange ye-aluminium ejwayelekile kakhulu ingxubevange engu-7075. Icishe iqine njengensimbi, kodwa inesisindo esisodwa kuphela kwezintathu zensimbi. Ivame ukusetshenziswa ezingxenyeni zomshini we-CNC, i-fuselage yendiza kanye namaphiko, amagobolondo e-smartphone kanye ne-rock climbing carabiner, njll. Nokho, ama-alloys anjalo anzima ukushisela, futhi ikakhulukazi, awakwazi ukushiswa ngendlela esetshenziselwa ukukhiqizwa kwezimoto, ngaleyo ndlela awenze angasetshenziswa. . Lokhu kungenxa yokuthi lapho i-alloy ishiswa ngesikhathi senqubo yokushisela, ukwakheka kwayo kwamangqamuzana kubangela ukuthi izakhi ze-aluminium, i-zinc, i-magnesium nethusi zigeleze ngokungalingani, okuholela ekuqhekekeni komkhiqizo oshiselwe.

Manje, onjiniyela be-UCLA bajova i-titanium carbide nanoparticles ocingweni lwe-AA7075, okuvumela lezi nanoparticles ukuthi zisebenze njengesigcwalisi phakathi kwezixhumi. Ukusebenzisa le ndlela entsha, ijoyinti elishiselwe elikhiqiziwe linamandla aqinile afinyelela ku-392 MPa. Ngokuphambene, amajoyinti ashiselwe i-aluminium alloy AA6061, asetshenziswa kakhulu ezindizeni nasezintweni zezimoto, anamandla aqinile angama-186 MPa kuphela.

Ngokusho kocwaningo, ukwelashwa kokushisa ngemuva kokushisela kungakhuphula amandla okuhlangana kwe-AA7075 kuya ku-551 MPa, eqhathaniswa nensimbi. Ucwaningo olusha luphinde lwabonisa ukuthi izintambo zokugcwalisa zigcweleTiC titanium carbide nanoparticleskungabuye kuhlanganiswe kalula nezinye izinsimbi nama-alloys ensimbi okunzima ukuwashisela.

Ophethe lolu cwaningo uthe: “Lobu buchwepheshe obusha kulindeleke ukuthi zenze le ngxube ye-aluminium enamandla amakhulu isetshenziswe kabanzi emikhiqizweni engenziwa ngezinga elikhulu, njengezimoto noma amabhayisikili. Izinkampani zingasebenzisa izinqubo ezifanayo kanye nemishini esezinayo kakade. Ingxubevange ye-aluminium enamandla kakhulu ihlanganiswa nenqubo yokukhiqiza ukuze ilula futhi isebenzise amandla kakhudlwana kuyilapho igcina amandla ayo.” Abacwaningi basebenze nomkhiqizi wamabhayisikili ukuze basebenzise le ngxubevange emizimbeni yamabhayisikili.
