Raws li peb txhua tus paub, ntxiv ntau hom hlau rau hauv cov hlau sib xyaw ua rau cov khoom siv tawg. Txawm li cas los xij, cov hlau sib xyaw ua ke siab (HEAs) txawv ntawm cov hlau sib xyaw ua ke: lawv muaj ntau yam hlau tab sis tsis qhia txog kev tawg, ua rau lawv yog cov khoom siv tshiab.
Hauv kev tsim khoom lag luam, kev ua kom ruaj khov thiab sib xws ntawm cov khoom siv high-entropy alloy yog qhov tseem ceeb heev. Vim li no, Vickers hardness testers yog siv los ua qhov kev ntsuam xyuas hardness ntawm high-entropy alloys thaum lub sijhawm tsim khoom, uas ua rau pom tau cov teeb meem zoo raws sijhawm. Yog tias tus nqi hardness txawv ntawm qhov xav tau, nws yuav qhia txog qhov tsis zoo hauv cov txheej txheem tsim khoom - xws li kev tswj hwm tsis raug ntawm cov khoom sib xyaw lossis cov txheej txheem kho cua sov tsis raug. Los ntawm kev kho cov txheej txheem tsim khoom sai sai, txhua pawg ntawm cov khoom siv high-entropy alloy tuaj yeem ua tau raws li cov qauv zoo, yog li txhim kho tus nqi tsim nyog thiab kev ntseeg siab ntawm cov khoom.
Peb tau txais cov qauv hauv qab no uas xav tau los kuaj qhov nyuaj.
Cov txheej txheem ntawm kev sim qhov nyuaj ntawm HEA los ntawm Vickers hardness tester
1. Ua qhov kev npaj ntawm HEA no rau hauv cov qauv txheem los ntawm kev nias lub tshuab tsis siv neeg, peb tuaj yeem sim nws qhov nyuaj los ntawm Vickers hardness tester tom qab sib tsoo thiab polishing.
2. Muab cov qauv tso rau ntawm qhov chaw ua haujlwm ntawm Vickers hardness tester.
3. Kho qhov kev tsom mus rau lub hom phiaj kom pom cov duab meej hauv Vickers hardness tester software.
4. Teem cov kev ntsuas ntawm cov qauv HEA uas tau sim hauv Vickers hardness tester software.
5. Tus indenter ua ib qho rhombus indentation ntawm HEA qauv nto, ces nyem lub pob Auto Measurement kom tau txais tus nqi hardness hauv Vickers hardness tester software.
6. Kev Ua Haujlwm Txheeb Xyuas: sau cov nqi ntsuas ntawm txhua pawg thiab tshem tawm cov outliers.
7. Kev Ua Haujlwm Txog Kev Txheeb Xyuas: Xam tus nqi nruab nrab thiab qhov sib txawv ntawm tus qauv.
Tus nqi siab tshaj plaws ntawm HEA raug kuaj los ntawm Model HVT-50A, uas yog hom Vickers hardness testers muag kub hauv peb lub tuam txhab.
