Dab tsi yog cov yam ntxwv yooj yim ntawm kev kho cua sov? Kev Txhim Kho Cov Khoom Siv Khoom Siv

Kev kho cua sov yog ib qho txheej txheem tseem ceeb hauv kev tsim kho ntawm lub cev thiab qee zaum cov khoom siv hluav taws xob, thiab kev kho kom sov, thiab ductility. Ib qho ntxiv, tus muaj pes tsawg leeg ntawm cov khoom siv thiab cov kev kho mob kub tshwj xeeb (xws li anealing tshav kub, quenching, tempering kev kho mob kom tau txais cov khoom siv cua sov {}}

Cov Ntsiab Lus Tseem Ceeb:

Kev Ntsuam Xyuas: Nws yog ib qho tsim nyog los txuas ntxiv saib thiab kho qhov ntsuas kub kom tswj cov mob xav tau thoob plaws tus txheej txheem .
Cua sov thiab cua txias

Cov cua sov tus nqi: tus nqi uas cov khoom siv cuam tshuam rau micraltructure thiab cov khoom cua sov heev yuav tsis ua tiav qhov xav tau {}}}
Tus nqi txias: tus nqi ntawm kev txias txias, tshwj xeeb yog tom qab quenneness, tab sis nws tseem tuaj yeem tswj hwm lub hardness thiab tawv me me, tus nqi txias yuav tsum tau tswj .
Quenching nruab nrab: kev xaiv ntawm quenching nruab nrab (roj, dej, cua cuam tshuam thiab cov khoom kawg ntawm cov khoom .
Ib puag ncig ib puag ncig

Kev Kho Mob Hauv Tshav Ntuj: Cov huab cua thaum kho tshav kub (e {{
Kev tsis huv: kom muaj kev huv ib puag ncig huv huv yog qhov tseem ceeb los saib xyuas kev ncaj ncees ntawm cov khoom siv .
Cov Khoom Siv Cov Khoom Siv

Alloy cov ntsiab lus: Lub xub ntiag ntawm cov ntsiab lus yuav cuam tshuam rau cov txheej txheem kho cua sov thiab cov khoom siv kub thiab kub thiab txias}
Cov khoom sib thooj: Cov khoom siv ntawm cov khoom yuav tsum tau ua kom zoo nkauj kom ntseeg tau tias nws cov khoom siv tau zoo sib xws.
Kev Kho Cua Sov

Annaling: Cov txheej txheem ntawm cov khoom siv rau ib qho kub thiab txias thiab tom qab ntawd txias nws maj mam tshem tawm sab hauv kev ntxhov siab thiab nce ductility .
Quenching: tempering: sai sai txias los ntawm qhov kub kom nce zog, feem ntau ua raws li los ntawm tempering kom txo brittleness .
Tempering: cua sov cov khoom quenched rau qhov kub tsawg dua los txo cov brittleness thaum tswj cov hardness .
Cov ntaub ntawv hardening: txheej txheem uas ua rau tawv nqaij ntawm cov khoom thaum ua kom cov tub ntxhais mos mos thiab tawv {}
Yuav tsum muaj neeg kho tshuab cov khoom

Hardness: Lub peev xwm ntawm cov khoom siv los tiv thaiv deformation thiab hnav .
Tougness: lub peev xwm los nqus lub zog thiab deform plastically yam tsis tau tawg .
Ductility: Muaj peev xwm deform hauv qab kev ntxhov siab nyob rau hauv tensile muaj kev ntxhov siab, feem ntau ntsuas raws li elongation ua ntej tawg.
Kev nkag siab thiab kev tswj hwm cov khoom ntiag tug yuav tsum muaj nyob rau hauv kev kho cua sov yog qhov tseem ceeb kom ua tiav cov khoom siv uas xav tau raws li tau txais hauv daim ntawv thov .
