Tsis tshua muaj lub ntiaj teb kub-kub molybdenum daim hlau yog raws li molybdenum, doped nrog ib tug me me ntawm lub ntiaj teb tsis tshua muaj ntsiab lus, thiab yog tsim los ntawm hmoov metallurgy. Piv nrog cov ntshiab molybdenum phaj, nws muaj cov cuab yeej zoo dua thiab ua haujlwm kub. Nws txoj kev tsim khoom yog raws li nram no:
1. Siv molybdenum dioxide ua raw khoom, dope nws nrog lanthanum nitrate tov, thiab txo nws los ntawm lub cub hluav taws xob nyob rau hauv ib tug hydrogen cua ntawm 850-1000 degree kom tau txais 0.6% La2O3- Mo alloy hmoov nrog qhov nruab nrab particle loj ntawm Fisher 2-3um.
2. Cov hmoov tuaj yeem sintered los ntawm isostatic nias kom tau txais qhov kub-kub molybdenum phaj.
3. Tom qab qhib lub phaj molybdenum, kub dov thiab hla-rov qab sov dov tuaj yeem ua kom tau lub phaj tuab ntawm 1.00mm thiab tag nrho deformation tus nqi ntawm 95%.
Lub ntiaj teb tsis tshua muaj molybdenum phaj tseem muaj qhov zoo heev hauv chav tsev kub plasticity thiab toughness tom qab annealing ntawm 1700 degree. Tom qab annealing ntawm 1800 ~ 2000 degree, chav tsev kub plasticity thiab toughness txo me ntsis. Molybdenum daim hlau annealed ntawm 1100 degree muaj qhov zoo hauv chav tsev kub, tab sis lub toughness yog qis dua lub ntiaj teb tsis tshua muaj molybdenum daim hlau, thiab muaj qhov pom tseeb ntawm chav tsev kub brittleness tom qab annealing ntawm 1200 degree.
Lub recrystallization kub ntawm lub ntiaj teb tsis tshua muaj molybdenum phaj yog siab dua, thiab lub recrystallization termination kub yog 1700 degree, thaum lub recrystallization termination kub ntawm ntshiab molybdenum yog 1100 degree. Tom qab annealing ntawm 1200 degree, cov nplej recrystallized loj hlob sai.
Tsis tshua muaj ntiaj tebmolybdenumcov phaj muaj cov qauv sib txawv los ntawm molybdenum daim hlau, muab lawv zoo heev hauv chav sov toughness tom qab high-temperature annealing. Tom qab annealing ntawm 1800 degree, vim yog cov concentrated kev loj hlob ntawm crystal grains, lub dispersion particles kuj dispersed, thiab dislocation ceev yog txo, uas ua rau ib tug txo nyob rau hauv lub nam piv ntawm cov nplej, yog li lub chav tsev kub toughness txo.
