HISTORY

Anosov was the first metallurgist to understand that
the structure of the metal, that is, the type and size of the
"grains" of which it consists, is a kind of metal passport.
Between the structure of this or that piece of metal, he
defined, and its mechanical properties, hardness, flexibility,
etc., there is a close connection.
This great discovery of the Russian metallurgist later
became the cornerstone of one of the most important exact
sciences - metallography, which studies the relationship
between the structure and properties of metals.
Anosov, on the other hand, was honored to create
those methods for studying the structure of metals,
which to this day occupy the main place in the arsenal of
metallography. He was the first in the world to begin the so-

To do this, he etched the samples with a weak acid,
which, acting differently on areas of the sample with an unequal chemical composition, seemed
to "show" a previously hidden picture, made all the features of the metal structure clear.
Also, Anosov was the first in the world to use a microscope to study the structure of
metals.
Back in 1831, at the time of his first searches, he, examining the metal, wrote: "... the
patterns are barely perceptible in a microscope."
Nowadays, in dozens of institutes, hundreds of factory laboratories, researchers every
day examine etched macrosections, bend over microscopes to reveal another secret of metal,
to help create the metals of the future.
However, we would look in vain in the Western European technical literature for indications
of Anosov's primacy in the creation of these most important methods of studying metals.
In foreign publications, the English scientist Sorby is praised as the "father" of metallography,
who first used the microscope for the study of metals only in 1854 - 23 years later than the
Russian innovator.
