b. Siab melting point: Lub melting point ntawm zirconium yog siab heev, txog 1855 degrees Celsius. Qhov no tso cai rau zirconium alloys los tswj cov qauv kev ruaj ntseg nyob rau hauv high-temperature ib puag ncig thiab yog li ntawd ua tau zoo nyob rau hauv high-temperature daim ntaub ntawv.
c. Tsawg neutron absorption cross-section: Zirconium muaj qhov tsis tshua muaj neutron absorption cross-section, uas ua rau zirconium alloys dav siv hauv kev lag luam nuclear, tshwj xeeb tshaj yog hauv kev tsim hluav taws xob nuclear.
d. Cov khoom siv zoo heev: Zirconium alloy muaj cov khoom siv zoo, nrog rau lub zog siab thiab hardness, uas ua rau nws siv rau qee qhov tshwj xeeb kev lag luam, xws li aerospace thiab nuclear industries.
3. Daim ntawv thov teb Zirconium alloy feem ntau yog siv hauv cov teb hauv qab no:
a. Kev lag luam Nuclear: Zirconium alloy yog siv dav hauv kev tsim cov roj hluav taws xob nuclear. Vim nws tsis tshua muaj neutron absorption cross-section, nws dhau los ua cov khoom siv zoo tshaj plaws hauv cov reactors nuclear.
b. Kev lag luam tshuaj lom neeg: Vim nws superior corrosion kuj, zirconium alloy yog siv nyob rau hauv kev lag luam tshuaj los lis corrosive media xws li muaj zog acids, alkali thiab ntsev tov.
c. Aerospace : Nyob rau hauv aerospace teb, zirconium alloys feem ntau yog siv los tsim cov kub kub, siab zog qhov chaw, xws li cav qhov chaw thiab missile lug.
d. Kev kho mob: Vim lub biocompatibility ntawm zirconium alloy, nws yog siv nyob rau hauv kev kho mob teb los tsim tej yam kev kho mob, xws li cov pob qij txha thiab cov ntaub ntawv kho hniav.
Qhov ceev: Zirconium alloy muaj qhov ntom ntom dua, txog 6.5 g / cm³, uas hnyav dua titanium.
Lub zog: Zirconium alloy muaj lub zog siab, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias, tab sis tus txheeb ze lub zog yuav qis.
Corrosion kuj: Zirconium alloy muaj qhov zoo tiv thaiv corrosion, tshwj xeeb tshaj yog rau cov kua qaub thiab alkaline xov xwm.
Thermal neutrality: Zirconium alloy yog dav siv nyob rau hauv nuclear kev lag luam vim hais tias nws pom zoo stability nyob rau hauv nruab nrab thiab high-temperature radioactive ib puag ncig.
Nuclear daim ntaub ntawv: Zirconium alloy feem ntau yog siv nyob rau hauv nuclear fais fab nroj tsuag ua roj pas cov khoom vim nws tsis tshua muaj neutron absorption cross-section.
Thermal expansion coefficient: Lub thermal expansion coefficient ntawm zirconium alloy yog qhov qis thiab sib tw zoo nrog qee yam khoom siv.
titanium alloys thiab zirconium alloysmuaj sib xws:
Biocompatibility: Ob leeg titanium thiab zirconium alloys muaj biocompatibility zoo thiab yog li siv dav hauv kev kho mob.
Corrosion kuj: Ob leeg muaj corrosion kuj zoo, tab sis muaj qhov sib txawv adaptability nyob rau hauv txawv ib puag ncig tej yam kev mob.
