Lub ductility ntawm tungsten alloy yog hais txog cov yas deformation muaj peev xwm ntawm cov khoom siv hlau ua ntej nws ruptures vim muaj kev ntxhov siab.Nws yog kev sib xyaw ua ke ntawm cov khoom siv kho tshuab nrog cov ntsiab lus zoo sib xws ntawm ductility thiab ductility, thiab cuam tshuam los ntawm ntau yam, nrog rau cov khoom muaj pes tsawg leeg, raw khoom piv, txheej txheem ntau lawm, thiab kev kho tom qab.Cov hauv qab no feem ntau qhia txog kev cuam tshuam ntawm impurity ntsiab ntawm ductility ntawm tungsten alloys.
Cov impurity ntsiab nyob rau hauv high density tungsten alloys muaj xws li carbon, hydrogen, oxygen, nitrogen, phosphorus, thiab sulfur ntsiab.
Cov ntsiab lus carbon: Feem ntau hais lus, raws li cov ntsiab lus carbon nce, cov ntsiab lus ntawm tungsten carbide theem hauv cov hlau kuj nce, uas tuaj yeem txhim kho hardness thiab lub zog ntawm tungsten alloy, tab sis nws cov ductility yuav txo.
Hydrogen caij: Thaum kub kub, tungsten reacts nrog hydrogen keeb los tsim hydrogenated tungsten, uas ua rau txo qis hauv cov ductility ntawm high density tungsten alloys, thiab cov txheej txheem no kuj ua hydrogen embrittlement.
Oxygen element: Feem ntau, muaj cov pa oxygen yuav txo cov ductility ntawm high density tungsten alloys, feem ntau vim tias cov pa oxygen yuav tsim cov oxides ruaj khov nrog tungsten, uas yuav ua rau muaj kev ntxhov siab ntawm cov ciam teb thiab hauv cov nplej.
Nitrogen: Qhov sib ntxiv ntawm nitrogen tuaj yeem txhim kho lub zog thiab hardness ntawm lub ntiajteb txawj nqus tshwj xeeb tungsten alloys, vim tias kev tsim cov khoom sib tov ntawm nitrogen thiab tungsten atoms yuav ua rau lattice distortion thiab ntxiv dag zog.Txawm li cas los xij, yog tias cov ntsiab lus nitrogen siab dhau lawm, kev sib txawv ntawm cov lattice thiab tshuaj lom neeg cov tshuaj tiv thaiv yuav ua rau muaj kev nce hauv brittleness ntawm cov hlau, yog li txo nws cov ductility.
Phosphorus: Phosphorus tuaj yeem nkag mus rau qhov siab ceev tungsten alloys los ntawm phosphide impurities hauv cov ntaub ntawv raw lossis cov pa phem thaum lub sijhawm tsim khoom.Nws muaj peev xwm ua rau embrittlement ntawm grain ciam teb, yog li txo cov ductility ntawm alloy.
Sulfur element: Sulfur ntsiab txhawb kev loj hlob ntawm cov nplej, uas nyob rau hauv lem cuam tshuam rau cov khoom siv thiab ductility ntawm tungsten alloys.Tsis tas li ntawd, leej faj kuj tuaj yeem tsim cov nkig sulfides ntawm cov ciam teb thiab cov nplej ntxhib, ntxiv kom txo tau cov ductility thiab toughness ntawm cov hlau.
