Metallic Crystallites - crystallites that have naru br ene constant geometric shape
Modifiers - substances added to form small crystallites in a liquid metal
Den d ri r - crystal in the form of a branchy tree
A l Lothrop (polymorphism) - may be due to the formation of molecules with different numbers of atoms or the formation of crystals of different modifications
Alloy - substance of two or more metals, obtained from mixing them during melting e
Pseudo- p lava - alloys formed without a rail izheni I elements, such as by electrolysis, and other methods of sublimation
System - alloys are also called systems
Component - each of the elements that make up the alloys
M ex and mixtures nical - alloys, the components of which are dissolved in the liquid state, but do not dissolve in the solid state and do not form a chemical compound between themselves
Solid solutions - homogeneous solids, consisting of several components, the concentrations of which can be changed without destroying the homogeneity
Chemical compounds - alloys, which are formed as a result of the chemical reaction of the components in the process of primary crystallization
