that is, a measure of a noncrystalline material’s resistance to permanent deformation vitrification During firing of a ceramic body, the formation of a liquid phase that upon cooling becomes a glass-bonding matrix vulcanization A nonreversible chemical reaction involving sulfur or an other suitable agent wherein crosslinks are formed between molecular chains in rubber materials The rubber’s modulus of elasticity and strength are enhanced W wave-mechanical model An atomic model in which electrons are treated as being wavelike weight percent (wt%) A concentration specification on the basis of weight (or mass) of a particular element relative to the total alloy weight (or mass) weld decay Intergranular corrosion that occurs in some welded stainless steels at regions adjacent to the weld welding A technique for joining metals in which actual melting of the pieces to be joined occurs in the vicinity of the bond A filler metal may be used to facilitate the process whisker A very thin, single crystal of high perfection that has an extremely large length-to-diameter ratio Whiskers are used as the reinforcing phase in some composites white cast iron A low-silicon and very brittle cast iron in which the carbon is in combined form as cementite; a fractured surface appears white whiteware A clay-based ceramic product that becomes white after high-temperature firing; whitewares include porcelain, china, and plumbing sanitary ware working point (glass) The temperature at which a glass is easily deformed, which corresponds to a viscosity of 103 Pa # s (104 P) wrought alloy A metal alloy that is relatively ductile and amenable to hot working or cold working during fabrication Y yielding The onset of plastic deformation yield strength (␴y) The stress required to produce a very slight yet specified amount of plastic strain;
