K D36 steel phaj

 

 

Mechanical Property Hloov

 

Yield zog txhim kho: Tom qab KD36 steel phaj tau txais kev kho kev laus, cov precipitates (xws li carbides, nitrides, thiab lwm yam) thaum lub sij hawm laus txheej txheem yuav impede dislocation txav. Nws zoo li teeb tsa ntau yam teeb meem ntawm txoj kev, thiab qhov kev tsis sib haum xeeb yuav tsum tau kov yeej ntau dua kev tawm tsam. Piv txwv li, nyob rau hauv cov kev laus tsim nyog, lub zog yield tuaj yeem txhim kho tau zoo, ua rau cov khoom siv tau zoo dua tuaj yeem tiv thaiv sab nraud yam tsis muaj qhov pom tseeb ntawm cov yas deformation. Qhov no yog qhov tseem ceeb heev rau kev nyab xeeb ntawm cov qauv xws li nkoj.

 

Tensile zog hloov: Lub zog tensile kuj tseem yuav hloov. Feem ntau, nrog kev kho kom zoo ntawm microstructure thiab nag lossis daus ntxiv zog thaum lub sij hawm kev laus, lub zog tensile yuav nce. Txawm li cas los xij, yog tias lub sijhawm laus ntev dhau los lossis qhov ntsuas kub tsis raug tswj tau zoo, ua rau muaj kev loj hlob ntau dhau ntawm precipitates lossis coarsening ntawm microstructure, lub zog tensile yuav txo.

 

Toughness thiab Ductility hloov: Kev laus kev kho mob muaj kev cuam tshuam rau toughness thiab ductility. Nyob rau hauv lub sij hawm thaum ntxov ntawm kev laus, vim dispersed tis ntawm precipitates, lub toughness thiab ductility ntawm cov khoom yuav txo me ntsis vim hais tias cov precipitates txwv tsis pub txav ntawm dislocations rau qee qhov, ua rau cov khoom muaj feem cuam tshuam rau pob txha thaum deformation. Txawm li cas los xij, yog tias cov txheej txheem kev laus raug tswj kom zoo kom cov dej nag sib npaug sib npaug thiab qhov loj me, qhov toughness thiab ductility tuaj yeem khaws cia rau qee qhov, thiab qee zaum, lub toughness kuj tseem tuaj yeem txhim kho.

Kev hloov pauv ntawm lub cev

 

 

Coefficient ntawm Thermal Expansion Hloov: Cov coefficient ntawm thermal expansion ntawm KD36 steel phaj kuj tseem yuav hloov vim kev laus kho. Hom kev sib txuas ntawm cov tshiab - tsim precipitates thiab cov matrix thiab lawv cov yam ntxwv sib txawv thermal expansion yuav ua rau muaj kev hloov pauv ntawm tus cwj pwm ntawm cov khoom thaum nws yog rhuab thiab nthuav. Hauv qee qhov kev siv nrog cov kev xav tau siab rau qhov tseeb qhov tseeb, xws li precision mechanical structures, qhov kev hloov pauv ntawm cov coefficient ntawm thermal expansion yuav tsum xav txog.

 

Corrosion Resistance Hloov: Cov kev hloov hauv microstructure tom qab kev laus kho yuav cuam tshuam rau corrosion kuj ntawm KD36 steel phaj. Yog tias cov txheej txheem kev laus ua rau kev tsim cov yeeb yaj kiab dense oxide ntawm cov khoom sib dhos lossis nws tuaj yeem txhim kho cov xeb corrosion. Piv txwv li, qee cov ntsiab lus alloy yog enriched rau ntawm qhov chaw thaum lub sij hawm laus txheej txheem los tsim ib tug tiv thaiv zaj duab xis, tiv thaiv corrosive nruab nrab los ntawm kev tiv tauj lub hauv paus hlau. Ntawm qhov tsis sib xws, yog tias kev laus ua rau muaj qhov tsis xws luag hauv microstructure, xws li cov khoom tsis sib xws ntawm cov nag lossis daus ntawm cov ciam teb, nws tuaj yeem txo qhov kev tiv thaiv corrosion vim tias cov chaw tsis zoo no yog qhov pib ntawm corrosion.
