Definition of martensite in English:
martensite
noun ˈmɑːtɪnzʌɪtˈmɑrtnˌsaɪt
mass nounMetallurgy A hard and very brittle solid solution of carbon in iron that is the main constituent of hardened steel.
Example sentencesExamples

- The ability of steel to form martensite on quenching is referred to as the hardenability.
- Trip steels have a microstructure with retained austenite, ferrite and martensite.
- During this heat treatment all of the austenite transforms to martensite.
- The martensite of quenched tool steel is exceedingly brittle and highly stressed.
Derivatives
adjective
Metallurgy The martensitic stainless steels can be welded in the annealed or fully hardened condition, usually without preheat or postheat.
Example sentencesExamples
- Exceptions include highly alloyed ferritic stainless steels, some of the martensitic stainless steels, and a few of the free-machining grades.
- The swirler is formed of a powder sintered compact of martensitic stainless steel having corrosion resistance and wear resistance.
- The martensitic, age-hardenable martensitic and semi-finished grades are used for small forgings.
- The martensitic stainless steels are hardenable by heat treatment and are magnetic.
Origin
