Spheroidized structure

Metals; Metallurgy

A microstructure consisting of a matrix containing spheroidal particles of another constituent.

Speroidizing annealing

Metals; Metallurgy

A subcritical annealing treatment intended to produce spheroidization of cementite or other carbide phases.

Spalling

Metals; Metallurgy

The cracking and flaking of particles out of a surface.

Specific gravity

Metals; Metallurgy

A numerical value representing the weight of a given substance as compared with the weight of an equal volume of water, for which the specific gravity is taken as 1. 0000.

Space lattice

Metals; Metallurgy

A system of equivalent points formed by the intersections of three sets of planes parallel to pairs of principal axes; the space lattice may be thought of as formed by the corners of the unit cells.

Sorbitic pearlite

Metals; Metallurgy

Structure of steel resulting, on cooling under the proper conditions, from the decomposition of austenite; has a fine, lamellar appearance.

Sorbite

Metals; Metallurgy

Structure of steel, resulting from the tempering of martensite. In a truly sorbitic structure, the cementite is completely dispersed in the matrix. The trend is to call this structure tempered ...
