Njengoko sonke sisazi, ukongeza ezinye iintlobo zeentsimbi kwi-alloy kudla ngokuyiqhekeza loo nto. Nangona kunjalo, ii-alloys ezine-entropy ephezulu (ii-HEA) zahlukile kwii-alloys eziqhelekileyo: ziqulathe iintsimbi ezininzi kodwa azibonisi ukuqhekeka, nto leyo ezenza zibe ludidi olutsha lwezinto.
Kwimveliso yemizi-mveliso, ukuqinisekisa uzinzo kunye nokungaguquguquki kweemveliso ze-alloy ezine-entropy ephezulu kubalulekile. Ngenxa yesi sizathu, abavavanyi bobulukhuni beVickers basetyenziselwa ukwenza uvavanyo lobulukhuni kwii-alloy ezine-entropy ephezulu ngexesha lenkqubo yemveliso, nto leyo evumela ukubonwa ngokukhawuleza kweengxaki zomgangatho. Ukuba ixabiso lobulukhuni liyaphambuka kuluhlu olulindelekileyo, linokubonisa iziphene kwinkqubo yemveliso—njengolawulo olungachanekanga lokwakheka kwe-alloy okanye iinkqubo zonyango lobushushu ezingafanelekanga. Ngokulungisa inkqubo yemveliso ngokukhawuleza, iqela ngalinye leemveliso ze-alloy ezine-entropy ephezulu linokufikelela kwimigangatho yomgangatho, ngaloo ndlela liphucula izinga lokufaneleka kwemveliso kunye nokuthembeka.
Sifumana isampuli efunekayo ukuze kuvavanywe ubulukhuni ngezantsi.
Iinkqubo zovavanyo lobunzima be-HEA nguVickers hardness tester
1. Yenza ulungiselelo lwesampulu yale HEA ibe yibhloko yesampulu eqhelekileyo ngomatshini wokuyibeka ngokuzenzekelayo, ukuze sivavanye ubulukhuni bayo ngesixhobo sokuvavanya ubulukhuni beVickers emva kokuyigaya nokuyipolisha.
2. Beka isampuli kwiziko lokusebenzela ngokuthe ngcembe lesixhobo sokuvavanya ubunzima beVickers.
3. Lungisa ingqwalasela ejolise kuyo ukuze ibonise umfanekiso ocacileyo kwisoftware yokuvavanya ubulukhuni beVickers.
4.Seta iiparameter zesampulu ye-HEA evavanyiweyo kwisoftware yokuvavanya ubulukhuni beVickers.
5. I-indenter yenza i-rhombus indentation kumphezulu wesampulu ye-HEA, uze ucofe iqhosha le-Auto Measurement ukuze ufumane ixabiso lobunzima kwisoftware yokuvavanya ubunzima beVickers.
6. Umsebenzi wezibalo: urekhoda amaxabiso alinganisiweyo eqela ngalinye aze asuse ngokuzenzekelayo izinto ezingaphandle.
7. Umsebenzi wezibalo: Bala ixabiso eliphakathi kunye nokuphambuka okuqhelekileyo.
Ixabiso lobunzima be-HEA elingaphezulu kwe-HV livavanywa yiModel HVT-50A, oluluhlobo oluthengiswa kakhulu lwabavavanyi bobunzima beVickers kwinkampani yethu.
