alloys; heat conduction of nickel and nickel-base alloys; ductility of 
refractory steels; heat resistance of austenitic-ferritic weld metals; 
welding of heat-resistant steels; and plasticity properties of fireproof 
steels. 
Other studies concerned the use of Constantan wires as strain gages; 
use of ultrasound in preparing suspensions; analysis and calculation of the 
combustion of coal dust; equation for stress relaxation of fastening 
materials; aerodynamics of furnace cyclone chambers; and the bending of 
curved thin-walled tubes. 
The Institute has a gas-turbine laboratory, a laboratory of 
radiation heat exchange, a welding laboratory, and a laboratory of long-time 
strength. A branch of the Institute is located in Moscow. 
A Trudy is published by the Institute, and the Degree of Candidate 
of Technical Sciences is awarded.
