Kev cuam tshuam ntawm Low Yield Strength ntawm Plasticity

 

Yooj yim nkag mus rau Plastic Deformation Theem
Hlau nrog lub zog qis zog, xws li Q235 steel, yuav pib tsim cov yas deformation nyob rau hauv kev ntxhov siab me me. Qhov no yog vim qhov kev ntxhov siab tus nqi sib xws rau nws qhov taw tes tawm los tsawg. Thaum lub zog sab nraud mus txog qhov ntsuas qis qis, cov qauv siv lead ua hauv cov hlau pib plam, thiab kev txav txav txav zuj zus, yog li ua rau cov hlau muaj qhov pom tseeb ntawm cov yas deformation. Piv txwv li, hauv qee cov tswv cuab hauv tsev yooj yim, xws li cov purlins ntawm cov tsev khaws khoom me me, thaum raug lub ru tsev loads thiab lawv tus kheej qhov hnyav, yog siv cov hlau uas muaj lub zog qis dua, qee qhov ntawm cov yas deformation yuav tshwm sim hauv kev pabcuam ib txwm muaj. loads.

 

Ntau dua cov yas deformation muaj peev xwm
Txij li cov hlau tsis tshua muaj zog tuaj yeem nkag mus rau cov yas deformation ua ntej, nws tuaj yeem tiv taus qhov deformation loj dua yam tsis muaj kev puas tsuaj rau theem no. Cov yam ntxwv no ua rau hom hlau no haum rau qee lub sijhawm uas yuav tsum tau ua cov yas. Piv txwv li, nyob rau hauv lub txias - dabtsi yog khoov txoj kev, Q235 steel yuav yooj yim dua khoov mus rau hauv ntau yam duab vim hais tias nws muaj peev xwm hloov mus rau lub puab pwm los ntawm nws tus kheej yas deformation thaum lub sij hawm khoov txheej txheem thiab yuav tsis tawg vim ntxov ntxov mus txog lub zog. txwv.

Kev cuam tshuam ntawm High Yield Strength ntawm Plasticity

 

Nyuaj nkag mus rau Plastic Deformation Stage
Cov hlau uas muaj lub zog muaj zog, xws li Q420 steel, yuav tsum muaj kev ntxhov siab ntau dua kom cov hlau pib tsim cov yas deformation. Qhov no yog vim hais tias nws cov qauv siv lead ua sab hauv yog ntau compact thiab lub zog khi ntawm atoms muaj zog dua. Txhawm rau ua kom muaj kev txav mus los thiab siv lead ua plam tshwm sim, yuav tsum muaj lub zog sab nraud ntau dua los kov yeej qhov kev sib khi no. Hauv cov qauv tsim, rau cov tswv cuab tseem ceeb ntawm cov tsev siab-nce, siv high-yield-lub zog steel tuaj yeem ua kom nws nyob rau hauv qhov elastic deformation ntau yam thaum coj tus qauv tsim loj dua thiab txo cov yas deformation tsis tsim nyog.

 

Relatively txwv cov yas deformation muaj peev xwm
Txawm hais tias siab - tawm los - lub zog steel kuj tuaj yeem tsim cov yas deformation tom qab yielding, nws cov yas deformation ntau kuj nqaim. Qhov no yog vim hais tias tom qab ncav cuag lub zog muaj zog dua, cov qauv microscopic hauv cov hlau twb tau tiv thaiv kev ntxhov siab loj, thiab kev deformation tsis tu ncua tuaj yeem ua rau muaj kev nthuav dav ntawm sab hauv tsis xws luag (xws li micro - tawg). Piv txwv li, thaum lub sij hawm lub tensile xeem ntawm Q420 steel, lub strain ntau yam uas nws muaj peev xwm tiv tau nyob rau hauv lub yas deformation theem tom qab yielding yog me dua li ntawm cov hlau uas muaj zog yield zog. Yog hais tias tus kab mob siab tshaj ib qho kev txwv thaum lub sij hawm cov txheej txheem yas deformation ntawm cov hlau no, nws yuav ua rau cov hlau tawg.

 

Obvious Strain - hardening Phenomenon tom qab yas deformation
Tom qab high-yield - lub zog steel undergoes yas deformation, lub strain - hardening index yog siab. Qhov no ua rau muaj kev ntxhov siab ntau ntxiv thaum lub zog nce ntxiv thaum lub sijhawm deformation. Piv txwv li, nyob rau hauv lub tensile xeem ntawm ib co high-lub zog alloy steels, thaum cov hlau nkag mus rau hauv lub yas deformation theem, txoj kab nqes ntawm nws txoj kev ntxhov siab - strain nkhaus yog loj, qhia tias lub peev xwm ntawm cov hlau los tiv thaiv deformation thaum lub sij hawm tas li deformation nce sai heev. . Qhov kev pom tseeb no - qhov tshwm sim hardening tuaj yeem ua rau cov hlau tuaj yeem tiv thaiv kev deformation ntxiv rau qee qhov, tab sis tib lub sijhawm, nws kuj tseem tuaj yeem ua rau kev ua haujlwm - cov teeb meem nyuaj thaum ua tom ntej lossis siv cov hlau, cuam tshuam rau nws cov kev ua haujlwm yas ntxiv.
