Sekureva kwemushumo wenguva pfupi yapfuura wePhysicist Organisation Network, mainjiniya epaYunivhesiti yeCalifornia, Los Angeles, vakashandisa titanium carbide nanoparticles kugadzira iyo yakajairwa yakakosha aruminiyamu alloy AA7075, isingagone kubatanidzwa kuti iite welded. Chigadzirwa chinobuda chinotarisirwa kushandiswa mukugadzira mota uye mamwe minda kuita kuti zvikamu zvaro zvireruke, zvine simba zvakanyanya, uye zvirambe zvakasimba.
Iyo yakanyanya kusimba yeakajairika aruminiyamu alloy ndiyo 7075 alloy. Inenge yakasimba sesimbi, asi inorema chikamu chimwe chete muzvitatu cheiyo yesimbi. Inowanzoshandiswa muCNC machined parts, fuselage ndege uye mapapiro, smartphone shells uye rock kukwira carabiner, etc. Zvisinei, alloys yakadaro yakaoma kupinza, uye kunyanya, haigoni kugadzirwa nenzira inoshandiswa mukugadzira motokari, zvichiita kuti irege kushandiswa. . Izvi zvinodaro nekuti kana iyo alloy ichidziya panguva yewelding, chimiro chayo chemolecular inoita kuti zvinhu zvinoumba aluminium, zinc, magnesium uye mhangura zviyerere zvisina kuenzana, zvichikonzera kutsemuka kwechigadzirwa chakasungwa.

Ikozvino, mainjiniya eUCLA anobaya titanium carbide nanoparticles muwaya yeAA7075, ichibvumira aya nanoparticles kuita sekuzadza pakati pezvibatanidza. Uchishandisa iyi nzira nyowani, iyo yakagadzirwa welded joint ine simba rekusimba kusvika 392 MPa. Kusiyana neizvi, iyo AA6061 aruminiyamu alloy welded majoini, ayo anoshandiswa zvakanyanya mundege nezvikamu zvemotokari, ane simba rekusimba re 186 MPa chete.

Maererano nekudzidza, kurapwa kwekupisa mushure mekugadzirisa kunogona kuwedzera simba rekubatana kweAA7075 kusvika ku551 MPa, iyo inofananidzwa nesimbi. Tsvagiridzo nyowani yakaratidzawo kuti waya dzekuzadza dzakazadzwa neTiC titanium carbide nanoparticlesinogona zvakare kubatanidzwa nyore nyore kune dzimwe simbi uye simbi alloys izvo zvakaoma kupinza.

Mukuru aitungamirira chidzidzo ichi akati: “Michina mitsva iyi inotarisirwa kuita kuti aruminiyamu iyi ine simba guru ishandiswe zvikuru muzvigadzirwa zvinogona kugadzirwa pamwero mukuru, zvakadai semotokari kana mabhasikoro. Makambani anogona kushandisa maitiro akafanana uye midziyo yavanotova nayo. Aruminiyamu yakasimba-yakasimba inosanganisirwa mukugadzira kwayo kuita kuti ireruke uye ishande nesimba ichiri kuchengetedza simba rayo. " Vatsvakurudzi vakashanda nemugadziri wemabhasikoro kuti vashandise alloy iyi pamitumbi yemabhasikoro.
