Yield Strength Sib txawv
Feem ntau hais lus, raws li lub thickness ntawm kub-dov hlau phaj nce, lub zog tawm los yuav txo. Piv txwv li, thinner kub - dov steel daim hlau (xws li cov thickness ntawm 3 - 5 hli) yuav muaj ib tug kuj siab yield zog, uas muaj peev xwm ncav cuag li ntawm 300 - 400MPa. Qhov no yog vim tias cov hlau nyias nyias muaj cov cua txias ceev ceev thaum lub sij hawm kub - dov txheej txheem. Lub degree ntawm grain refinement nyob rau hauv lawv cov qauv sab hauv yog siab dua, thiab cov dislocation ceev yog loj, uas yuav pab tau cov khoom muaj peev xwm tiv thaiv yas deformation.
Txawm li cas los xij, rau cov phaj tuab tuab tuab (xws li cov tuab ntawm 20 - 30 hli), lub zog tawm los yuav txo qis rau 200 - 300MPa. Cov phaj tuab tuab muaj qhov qis qis dua tom qab dov, thiab cov nplej muaj sij hawm ntau dua, ua rau cov qoob loo loj dua thiab yooj yim dua rau kev txav mus los, yog li lub zog tawm los txo qis.

Tensile Strength Sib txawv
Lub zog tensile ntawm nyias kub - dov steel phaj feem ntau yog siab. Cov hlau nyias nyias tau raug rau ib qho kev sib tw ntau dua thaum lub sij hawm kub - dov txheej txheem, thiab lawv cov qauv sab hauv yog ntau compact, ua kom lawv lub zog tensile ncav cuag tus nqi siab, feem ntau nyob ib ncig ntawm 400 - 500MPa.
Lub zog tensile ntawm tuab kub - dov steel phaj yog qhov tsawg. Vim lub thickness loj ntawm cov hlau tuab, tej zaum yuav muaj qhov sib txawv ntawm qhov deformation thiab lub koom haum lub xeev ntawm lub hauv paus thiab qhov chaw nto thaum lub sij hawm dov txheej txheem. Tej zaum yuav muaj qee qhov tsis sib xws hauv cov qauv sab hauv, xws li porosity. Lawv lub zog tensile yuav nyob ib ncig ntawm 300 - 400MPa.

Qhov txawv ntawm elongation
Thicker kub - dov steel phaj feem ntau muaj ntau dua elongation. Qhov no yog vim hais tias thaum tuab steel phaj yog raug rau tensile quab yuam, muaj ntau qhov chaw nyob rau hauv lawv kom haum yas deformation. Piv txwv li, qhov elongation ntawm kub - dov steel phaj nrog lub thickness ntawm 20mm los yog ntau tshaj yuav ncav cuag li 25% - 30%.
Lub elongation ntawm nyias kub - dov steel phaj yog qhov tsawg, feem ntau nyob ib ncig ntawm 15% - 20%. Vim hais tias tus ntoo khaub lig-seem ntawm nyias steel daim hlau yog me me thaum lub sij hawm stretching txheej txheem, lub zos kev nyuaj siab concentration phenomenon ntawm cov khoom yog kuj pom tseeb, thiab necking thiab lwm yam tshwm sim yuav tshwm sim, ua rau ib tug kuj me me elongation.

 

 

 

Impact Toughness txawv
Qhov cuam tshuam toughness ntawm nyias kub - dov steel daim hlau yog qhov tsawg. Vim tias lawv cov qauv yog qhov sib zog, thaum lawv raug cuam tshuam, qhov kev ntxhov siab yoj propagates ntawm qhov ceev ceev, thiab kev ntxhov siab concentration yuav tshwm sim, ua rau cov khoom tawg ntawm qhov cuam tshuam tsawg zog. Piv txwv li, qhov cuam tshuam toughness ntawm nyias steel daim hlau (nrog lub thickness ntawm 3 - 5 hli) yuav nyob ib ncig ntawm 30 - 50J.
