The reference book contains extensive material on the compositions, structures, properties and states of metals, functional relationships between them. The behavior of the material is described as a consequence of the interaction between defects in its structure and external loads, as well as from the point of view of the role of the thermodynamic state in the formation of driving forces and the kinetics of phase transformations. Thus, an end-to-end assessment of the metal, important for the machine builder, is possible: from its smelting to work in the machine.
