Xaiv qhov Kub Kub

 

Txoj Cai: Kev laus kub muaj feem cuam tshuam rau cov khoom ntawm cov hlau. Nyob rau hauv qis kub, qhov atomic diffusion tus nqi qeeb, lub nucleation tus nqi ntawm lub precipitated theem yog siab, tab sis qhov loj hlob qeeb, thiab nws yog ib qho yooj yim rau tsim ib tug nplua thiab dispersed precipitated theem. Raws li qhov kub thiab txias nce, atomic diffusion nrawm dua, qhov kev loj hlob ntawm theem precipitated yuav nrawm dua, thiab qhov loj tuaj yeem nce ntxiv. Nyob rau tib lub sijhawm, dislocation txav kuj yuav nrawm. Piv txwv li, rau KA36 steel, yog tias qhov kub thiab txias qis dhau lawm, txawm hais tias cov txheej txheem precipitated zoo tuaj yeem tau txais, lub sijhawm laus ntev dua yuav tsum ua kom muaj zog ntxiv. Yog tias qhov kub thiab txias dhau lawm, cov theem precipitated yuav loj hlob thiab coarsen sai, thiab tej zaum yuav ua rau over-aging ntawm cov khoom thiab ib tug txo nyob rau hauv lub zog ntawm cov nyhuv.

 

Kev txiav txim siab ntawm qhov tsim nyog qhov ntsuas kub: Feem ntau hais lus, los ntawm kev sim thiab kev tshawb fawb, rau KA36 steel, qhov kub ntawm qhov tsim nyog yuav nyob nruab nrab ntawm 150 - 250 degree . Qhov ntsuas kub no pab tsim cov theem precipitated ntawm qhov tsim nyog loj, uas tuaj yeem cuam tshuam kev txav mus los thiab ua kom lub zog tawm los, thiab tseem tuaj yeem zam kev loj hlob ntau dhau ntawm cov theem precipitated. Nyob rau hauv qhov ntsuas kub no, lub zog tensile thiab lub zog tawm los ntawm cov khoom tuaj yeem txhim kho zoo dua, thiab cov tawv nqaij thiab cov yas kuj tseem tuaj yeem tswj tau ntawm qhov tsim nyog.

 

Tswj Lub Sijhawm Laus

 

Txoj Cai: Lub sijhawm laus muaj feem cuam tshuam nrog kev loj hlob ntawm cov theem precipitated thiab stability ntawm cov khoom siv. Thaum ntxov ntawm kev laus, raws li lub sij hawm nce, lub precipitated theem tsis tu ncua nucleates thiab loj hlob, thiab lub zog ntawm cov khoom maj mam nce. Tom qab ib lub sij hawm ntawm lub sij hawm, txoj kev loj hlob ntawm precipitated theem maj stabilizes, thiab cov khoom siv kuj zoo li stabilize. Yog hais tias lub sij hawm aging txuas ntxiv mus, dhau - aging phenomena xws li coarsening ntawm lub precipitated theem thiab redistribution ntawm dislocations yuav tshwm sim, ua rau ib tug poob ntawm cov khoom. Siv KA36 steel ua piv txwv, nyob rau theem pib ntawm kev laus, qee qhov kev nce ntxiv ntawm cov khoom muaj zog tuaj yeem raug pom txhua teev, vim tias tus lej thiab qhov loj ntawm cov theem precipitated tau nce tas li.

 

Kev txiav txim siab txog lub sijhawm tsim nyog: Lub sijhawm laus tshwj xeeb yuav tsum tau txiav txim siab raws li yam xws li qhov kub thiab txias thiab cov khoom muaj pes tsawg leeg. Feem ntau, nyob rau hauv qhov kub thiab txias ntawm 150 - 250 degree, lub sij hawm laus tuaj yeem tswj tau ntawm 8 - 24 teev. Nyob rau hauv lub sijhawm no, qhov kev ua tau zoo ntawm KA36 steel tuaj yeem ua tiav qhov sib npaug zoo dua, muab kev ua si tag nrho rau lub luag haujlwm ntawm kev laus zog, ua kom zoo rau cov khoom siv xws li lub zog tawm los thiab lub zog tensile, thiab tiv thaiv kev ua haujlwm tsis zoo los ntawm kev laus.
