Definition of pearlite in English: pearlitenoun ˈpəːlʌɪtˈpərlīt mass nounMetallurgy A finely laminated mixture of ferrite and cementite present in cast iron and steel, formed by the cooling of austenite. Example sentencesExamples - The structure now consists of free cementite and pearlite.
- This reduces the amount of pearlite and improves toughness, ductility, and weldability.
- It is important to note that higher silicon contents can promote pearlite and may increase the nickel requirement.
- Ductility and impact properties are principally determined by the proportions of ferrite and pearlite in the matrix.
- The pearlite is responsible for substantial strengthening.
