Hauv kev tshawb fawb thiab kev tsim kho cov cemented carbide cov khoom, peb feem ntau coj "kev tswj hwm kom muaj peev xwm ua tau" ua lub hom phiaj tshawb fawb, txhawm rau kom tau txais kev ua tau zoo dua.

Zoo li cov ntaub ntawv hlau, cov tawv nqaij ntawm cov cemented carbide tuaj yeem qhia raws li kev cuam tshuam nyuaj thiab cov pob txha tawv tawv. Muaj kev sib raug zoo linear ntawm qhov kev cuam tshuam nyuaj thiab lub zog Flexural zog ntawm kev ua kom carbide. Qhov uas txiav txim siab lub zog ntawm lub zog ntawm cov alloy kuj tseem ceeb cuam tshuam rau qhov kev cuam tshuam nyuaj ntawm cov alloy. Qhov kev cuam tshuam nyuaj ntawm lub alloy kuj tseem cuam tshuam los ntawm lwm yam.

Kev cuam tshuam cov tawv tawv yog qhov muaj peev xwm ntawm cov khoom siv los tiv thaiv tsis tau ua tiav hauv kev cuam tshuam chaw thau khoom. Sab hauv tej yam tsis xws luag nyob rau hauv cov thoob plaws ib coloys muaj kev cuam tshuam zoo sib xws ntawm FLEXURAL lub zog thiab kev cuam tshuam todualness. Feem ntau, nyuaj alloys muaj cov ntaub ntawv loj heev, thiab Elastic deformation ua hauj lwm rau lub zog loj uas muaj kev cuam tshuam tseem ceeb ntawm qhov cuam tshuam muaj nqi.

Rau cov alloy muaj 10% CO, nrog rau kev nce ntawm WC grain loj, lub zog ua kom muaj zog zuj zus thiab muaj zog ua kom muaj zog, qhia txog lub zog yooj yim tshaj plaws

Raws li lub hardness ntawm cemented carbide nce ntxiv, lub pob txha tawv tawv tawv yuav txo qis. Tab sis nyob rau hauv qee qhov ntau, nws qhia tau tias lwm yam tseem ceeb tseem cuam tshuam rau cov pob txha tawv nruj nyob hauv tib lub hardness.

Los ntawm kev txheeb xyuas qhov kev sib raug zoo ntawm qhov kev cuam tshuam nyuaj, pob txha pob zeb thiab lwm yam khoom siv hluav taws xob thiab cov txheej txheem sib txawv, peb kos cov ntsiab lus sib txawv, peb kos cov lus xaus hauv qab no:

Muaj ntau yam cuam tshuam rau cov kev cuam tshuam tawv tus nqi ntawm kev tso cai carbide, feem ntau yog suav nrog alloys muaj zog thiab cuam tshuam nyuaj tib lub sijhawm. Lub zog ntawm lub zog ntawm lub zog muaj qhov cuam tshuam zoo ntawm qhov kev cuam tshuam nyuaj.Qhov kev cuam tshuam nyuaj thiab lub zog Flexural zog tswj hwm ib txoj kev sib raug zoo. Tsuas yog nyob rau hauv cov xwm txheej ntawm FLEXURAL HOM FLEXTAL lub zog, alloys nrog zoo bacture nyuaj qhia tau zoo heev kev cuam tshuam cov kev cuam tshuam zoo.

Lub pob txha tawv tawv ntawm cov paemented carbide yog qhov tseem cuam tshuam nrog lub hardness. Raws li lub hardness ntawm alloy nce ntxiv, qhov xwm txheej nruj heev, txo qis dua linearly, tab sis hloov nyob rau hauv ib tug ntau yam. Thaum lub hardness yog zoo sib xws, cov coarse-grained alloy muaj zoo dua pob txha tawv. Homogeneous txheej txheem alloys muaj siab dua sim pob tab sis qis dua qhov muaj zog yooj yim thiab cuam tshuam nyuaj dua li cov qauv tsis muaj txheej txheem.

Piv nrog rau qhov cuam tshuam nyuaj ntawm cov cemented carbide, lub pob txha tawv tawv tawv muaj qhov tseem ceeb tshaj qhov tseem ceeb. Ua ke nrog peb cov txuj ci ua haujlwm ntawm pob txha tawv tawv, hardness thiab flexural zog ntawm alloy, nws tuaj yeem ua tau zoo dua cov kev ua tau zoo ntawm cov alloy.
