Main cases of damage of superheaters from steel 12Kh1MF due to disturbance of the process of production of the tubes and due to creep, thermal fatigue, and short-term superheating are considered. The methods of metallographic analysis and scanning electron microscopy are used to determine the special features of their microstructure and fracture surfaces. The results obtained are used to develop an algorithm for detecting the causes of damage in superheaters produced from heat-resistant pearlitic steels. © 2013 Springer Science+Business Media New York.

The effect of the parameters of austenization of a new sparingly-alloyed roll steel 70Kh3G2VTB on the phase composition and processes of dissolution of carbide phase is determined. The susceptibility of austenite grains to growth in heating is studied. The resistance of the steel to softening during tempering after quenching from various temperatures is estimated. © 2013 Springer Science+Business Media New York. Source

This is the second article on a method developed by TsNIITMASh to design forging ingots. The method makes it possible to eliminate axial porosity in the body of the ingot. Results are presented from a comparison of calculated data and experimental data obtained on the basis of the new method. It is shown that the calculated results agree satisfactorily with the experimental results. © 2012 Springer Science+Business Media, Inc. Source

This is the third and final article on a method developed by TsNIITMASh to design forging ingots so as to prevent the formation of an axial shrinkage cavity in the body of the ingot. Theoretical and experimental results from use of the method and factory-designed casting equipment to obtain such ingots are compared together with requirements of the standard OST 108.962.02-85. It is shown that the theoretical and experimental results agree satisfactorily with one another . © 2012 Springer Science+Business Media, Inc. Source
