A substance that bonds together the surfaces of two other materials (termed adherends). Adherend Alloy steel. A ferrous (or ironbased) alloy that contains appreciable concentrations of alloying elements (other than C and residual amounts of Mn, Si, S, and P). These alloying elements are usually added to improve mechanical and corrosion resistance properties. MnSiSP Brass. A copper-rich copperzinc alloy. - Bronze. A copper-rich coppertin alloy; aluminum, silicon, and nickel bronzes are also possible. - Calcination. A high-temperature reaction whereby one solid material dissociates to form a gas and another solid. It is one step in the production of cement. Cast iron. Generically, a ferrous alloy, the carbon content of which is greater than the maximum solubility in austenite at the eutectic temperature. Most commercial cast irons contain between 3.0 and 4.5 wt%C, and between 1 and 3 wt%Si. 3.0-4.5% C 1-3% Si Cement. A substance (often a ceramic) that by chemical reaction binds particulate aggregates into a cohesive structure. With hydraulic cements the chemical reaction is one of hydration, involving water.involving water....
