Patlisisong le nts'etsopele ea lihlahisoa tsa carbide tse samenteng, hangata re nka "ho boloka likarolo tse ling tsa carbide e samenteng le ho ntlafatsa ho tiea ha eona ka hohle kamoo ho ka khonehang" e le sepheo sa lipatlisiso, e le ho fumana tšebetso e ntlafetseng.

Joalo ka lisebelisoa tsa tšepe, ho tiea ha carbide e entsoeng ka samente ho ka bonts'oa ho latela boima ba tšusumetso le ho tiea ha fracture. Ho na le kamano e pakeng tsa matla a ts'usumetso le matla a flexural a carbide e entsoeng ka samente. Lintlha tse khethollang matla a flexural a alloy li boetse li ama ka matla ho tiea ha phello ea alloy. Tšusumetso e matla ea alloy e boetse e angoa ke lintlha tse ling.

Tšusumetso e matla ke bokhoni ba lisebelisoa ho hanela ho hloleha ha o ntse o kenya letsoho. Litšitiso tse ka hare ho li-alloys li na le liphello tse tšoanang ho matla a flexural le ho tiea ha tšusumetso. Ka kakaretso, li-alloys tse thata ke lisebelisoa tse brittle, 'me mosebetsi oa elastic deformation o ikarabella bakeng sa karolo e kholo ha e le tlas'a tšusumetso, kahoo matla a flexural a alloy a na le tšusumetso ea bohlokoa ho bohlokoa ba ho tiea ha tšusumetso.

Bakeng sa alloy e nang le 10% Co, ka keketseho ea boholo ba lijo-thollo tsa WC, le hoja boima ba ho robeha ha motsoako bo ntse bo eketseha, matla a flexural a fokotseha 'me boleng ba ts'ebetso ea ts'ebetso le bona bo fokotseha, ho bontša hore matla a flexural a phetha karolo ea bohlokoa ho matla a tšusumetso. .

Ha boima ba carbide e entsoeng ka samente bo ntse bo eketseha, ho thatafala ha fracture ho batla ho fokotseha. Empa ka har'a mefuta e itseng, e bontša hore lintlha tse ling le tsona li ama ho tiea ha fracture tlas'a boima bo tšoanang.

Ka ho sekaseka kamano lipakeng tsa matla a tšusumetso, ho tiea ha fracture le lisebelisoa tse ling tsa mochini le likarolo tsa sebopeho sa carbide e entsoeng ka lipina tse fapaneng, boholo ba karolo ea WC le maemo a fapaneng a ts'ebetso, re fihlela liqeto tse latelang:

Ho na le lintlha tse ngata tse amang phello ea toughness bohlokoa ba cemented carbide, haholo-holo ho akarelletsa le mefokolo ea sebopeho, matla le toughness, joalo-joalo. Matla a flexural a alloy a na le tšusumetso e kholo ho toughness ea tšusumetso.Bothata ba tšusumetso le matla a flexural a boloka kamano e itseng ea linear. Ke feela tlas'a boemo ba matla a tšoanang a flexural, li-alloys tse nang le bothata bo botle ba fracture li bontša ho ba le tšusumetso e matla.

Ho robeha ho thata ha carbide e entsoeng ka samente ho amana haholo le ho thatafala. Ha boima ba alloy bo ntse bo eketseha, ho tiea ha fracture ho fokotseha ka mokhoa o itekanetseng, empa ho fetoha ka har'a mefuta e itseng. Ha boima bo ts'oana, motsoako o tlase oa Coarse-grained o na le bothata bo betere ba ho robeha. Li-alloys tse entsoeng ka homogeneously li na le matla a holimo a ho robeha empa matla a fokolang a fokolang le ho ba le tšusumetso e matla ho feta li-alloys tse se nang homogeneously.

Ha ho bapisoa le boleng ba toughness ea carbide e entsoeng ka samente, boleng ba ho robeha ha fracture bo na le bohlokoa bo sebetsang haholoanyane. Ha e kopantsoe le matšoao a mararo a ts'ebetso ea mochini oa ho thatafala ha fracture, ho thatafala le matla a tenyetsehang a alloy, e ka bonts'a ts'ebetso ea alloy hamolemo.
