Structure of MetalsDOE-HDBK-1017/1-93ALLOYSThe important information in this chapter is summarized below.An alloy is a mixture of two or more materials, at least one of which is a metal.Alloy microstructuresSolid solutions, where secondary atoms introduced as substitutionals orinterstitials in a crystal lattice.Crystal with metallic bondsComposites, where secondary crystals are imbedded in a primarypolycrystalline matrix.Alloys are usually stronger than pure metals although alloys generally havereduced electrical and thermal conductivities than pure metals.The two desirable properties of type 304 stainless steel are corrosion resistanceand high toughness.Rev. 0Page 17MS-01
