Fatigue in Materials

Definition: The behavior of materials under fluctuating and reversing loads (or stresses) is known as fatigue. This behavior is different from that under the steady load. Fatigue is, however, not a dynamic effect. The rate of loading is usually not a factor in fatigue behavior. Fatigue behavior is experienced by all materials whether metals, plastics, […]

Crystal Structure Analysis by X Ray Diffraction

Crystal Structure Analysis by X Ray Diffraction Structures of solids can be determined by various techniques. Out of these techniques, X-rays and microscopic studies have helped immensely in studying crystallography of metals. Therefore these two techniques are very popular. Hence X-rays will be discussed in this article and microscopy is discussed in another one. X-RAYS

Classification of Solids

Classification of Solids Solids, on the basis of their structures, may be classified as: Examples of such solids are as under: Metallic solids: Na, Cu, Zn; compounds such as borides, hydrides, nitrides, carbides etc. formed by transition elements. Ionic solids: NaCl, Na2SO4, MgAl204, calcite (CaCO3), magnesia (Mg0), Zincblende (or sphalerite) ZnS having FCC structure, and
