Description: 
The Institute, founded in 1930, has placed heavy emphasis on 
diffusion studies in ferrous metallurgy. Among some of the areas covered 
are the influence of primary hardening on the diffusion speed of carbon in 
austenite, the mechanisms of diffusion, and the diffusion of various metals 
in carbon and noncarbon steels. The Institute has also studied the effect 
of various conditions of heat treatment and mechanical treatment on the 
structure and properties of ferrous metals, malleability of cast iron, 
internal friction in hardened and tempered steels, methods for hardening 
steels, and numerous other processes involving ferrous metallurgy. 
Selected studies have been performed at the Institute to determine 
satisfactory methods of automating and controlling production. One of these 
concerned the use of an analog computer in problems of structural mechanics, 
strength of materials, and theory of elasticity. Other developments pertained 
to automatic controlling and sorting machines. 
Precision quality controls by microspectral analysis and oscillo- 
graphic recording have also been implemented. 
The Institute places great emphasis on basic research in the fields 
of physics and mathematics. Several Trudys are published each year. 
Courses of study available at the Institute include machine-building 
technology, machine tools, equipment and technology of pressure working 
metals, automation and remote control, mining, mining equipment, and hoisting 
and transportation equipment.
