Martensite (Noun)
Meaning
A solid solution of carbon in alpha-iron that is formed when steel is cooled so rapidly that the change from austenite to pearlite is suppressed; responsible for the hardness of quenched steel.
Classification
Nouns denoting substances.
Examples
- Martensite is a solid solution of carbon in alpha-iron that forms in steel as it undergoes rapid cooling, leading to its characteristic hardness.
- During the quenching process, the austenite transforms into martensite, resulting in significantly increased strength and durability of the steel.
- The rapid cooling of steel prevents the formation of pearlite, allowing martensite to take its place and causing the steel to become stronger and more brittle.
- By adjusting the cooling rates of steel alloys, manufacturers can control the amount of martensite that forms, influencing the final properties of the material.
- The formation of martensite in steel is a critical factor in the heat treatment process, as it is responsible for its high hardness and resistance to wear.
