Ukusetshenziswa kwezinsimbi eziphikisayo

Izinsimbi eziphikisayo ziwuhlobo lwezinto zensimbi ezinokumelana nokushisa okuhle kakhulu nendawo yokuncibilika ephezulu kakhulu.

Lezi zakhi eziphikisayo, kanye nezinhlobonhlobo zezinhlanganisela nama-alloys ezakhiwe ngazo, zinezici eziningi ezivamile.Ngokungeziwe endaweni ephezulu yokuncibilika, futhi inokumelana nokugqwala okuphezulu, ukuminyana okuphezulu, futhi igcina amandla amahle kakhulu emishini emazingeni okushisa aphezulu.Lezi zici zisho ukuthi izinsimbi eziphikisayo zingasetshenziswa emikhakheni eminingi, njengama-electrode ancibilikisa ingilazi, izingxenye zesithando somlilo, okuhlosiwe okufafaza kuzo, ama-radiator nama-crucibles.Ochwepheshe boMnyango Wezobuchwepheshe we-RSM bethula izinsimbi ezimbili ezivame ukusetshenziswa kakhulu eziphikisayo kanye nezicelo zazo, okungukuthi, i-molybdenum ne-niobium.

i-molybdenum

Iyinsimbi ephikisayo esetshenziswa kakhulu kunazo zonke futhi inezakhiwo ezinhle kakhulu zemishini ngaphansi kwezinga lokushisa eliphezulu, ukunwetshwa okuphansi kwe-thermal kanye nokuhamba okuphezulu kwe-thermal.

Lezi zakhiwo zisho ukuthi i-molybdenum ingasetshenziswa ukwenza izingxenye ezihlala isikhathi eside zokusetshenziswa ukushisa okuphezulu, njengezingxenye ezithwalayo, amabhuleki e-elevator, izingxenye zomlilo, kanye nama-forging dies.I-Molybdenum isetshenziswa kuma-radiators ngenxa ye-thermal conductivity ephezulu (138 W/(m · K)).

Ngaphezu kwezakhiwo zayo zemishini nezokushisa, i-molybdenum (2 × 107S/m), eyenza i-molybdenum isetshenziselwe ukwenza i-electrode encibilikisa ingilazi.

I-molybdenum ivamise ukuxutshwa nezinsimbi ezihlukene ezisetshenziswayo ezidinga amandla okushisa, ngoba i-molybdenum isenamandla amakhulu ngisho nasezingeni eliphezulu lokushisa.I-TZM iyingxubevange yesisekelo se-molybdenum edumile, equkethe u-0.08% we-zirconium no-0.5% we-titanium.Amandla ale alloy ku-1100 ° C cishe aphindwe kabili kunalawo e-molybdenum engaxutshiwe, ngokunwebeka okuphansi okushisayo kanye nokuhamba okuphezulu kokushisa.

i-niobium

I-Niobium, insimbi ephikisayo, ine-ductility ephezulu.I-Niobium inokucutshungulwa okuphezulu ngisho nasezingeni eliphansi lokushisa, futhi inezinhlobo eziningi, njenge-foil, ipuleti kanye neshidi.

Njengensimbi ephikisayo, i-niobium inokuminyana okuphansi, okusho ukuthi ama-alloys e-niobium angasetshenziswa ukwenza izingxenye eziphikisayo ezisebenza kahle ezinesisindo esincane.Ngakho-ke, ama-alloys e-niobium afana ne-C-103 ngokuvamile asetshenziswa ezinjini zamarokhethi asemkhathini.

I-C-103 inamandla amahle kakhulu okushisa aphezulu futhi ingamelana namazinga okushisa afika ku-1482 ° C. Ibuye ihleleke kakhulu, lapho inqubo ye-TIG (Tungsten Inert Gas) ingasetshenziswa ukuyishisela ngaphandle kokuthikamezeka ngokuphawulekayo ukusebenziseka kalula noma i-ductility.

Ukwengeza, uma kuqhathaniswa nezinsimbi ezihlukene eziphikisayo, inengxenye ephambano ye-neutron eshisayo ephansi, ebonisa amandla esizukulwaneni esilandelayo sokusetshenziswa kwezikhali zenuzi.
