Professor B.A. Kolachev’s Scientific School
The main scientific results obtained by Prof. B.A. Kolachev and his followers are described. Some aspects of the hydrogen embrittlement origin and means to suppress the embrittlement are considered. Diagrams of critical hydrogen content causing embrittlement of titanium alloys are given. Articles by B.A. Kolachev about application of the plasticizing effect of hydrogen at different processing steps are listed. His crucial role in the progress of researches of phase transformation mechanisms occurring in titanium alloys is highlighted. Methods of computation of coefficients, which define phase composition of alloys depending on alloying and a method of computation of alloy strength depending on the value of the above coefficients are offered.
