    On the Kinetics of Chemical Reactions in Solids Under Shock Compression (a review) (1993)
    Weinheim : Wiley-Blackwell
    Propellants, Explosives, Pyrotechnics 18 (1993), S. 100-105 
    Details
    ISSN: 0721-3115
    Keywords: Chemistry ; Polymer and Materials Science
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Consideration is given to physical and chemical methods useful for a proceeding time of chemical reactions under compression due to impact and, also, to diffusion-process peculiarities. Experimental data enable us to conclude that solid-phase reactions may be accomplished for times of the order 1-10 μs. The mechanism governing enhanced diffusion rate at the moment of impact has been proposed and experimentally confirmed.

    On the Nature of Boron Nitride E-Phase (1993)
    Weinheim : Wiley-Blackwell
    Propellants, Explosives, Pyrotechnics 18 (1993), S. 352-355 
    Details
    ISSN: 0721-3115
    Keywords: Chemistry ; Polymer and Materials Science

    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: A review of the works, in which the E-phase of boron nitride had been obtained under various physical treatments, revealed that in all cases during the formation or isolation of the E-phase the sample can be impurified with oxygen. An X-ray spectral study of crystalline E-phase obtained in the present work proved it to be a solid solution of the type BN1 - xOx containing B-B bonds.

    Effect of High Dynamic Pressure on the Structure of Solids (1987)
    Weinheim : Wiley-Blackwell
    Propellants, Explosives, Pyrotechnics 12 (1987), S. 206-208 
    Details
    ISSN: 0721-3115

    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: The influence of shock waves on crystal macrostructure and its physical and technological consequences are discussed. The size of crystal particles grain corresponding to the transition of solid into amorphous state is estimated. The magnitudes of microstrains in crystals during their grinding are calculated. It is shown that under shock-wave treatment the grain size and microstrain are usually about 10 times differed from the values in amorphous substances. The possibility of amorphization during chemical interaction under shock compression is shown. Phase transformations with change of stoichiometry under shock waves prove a perspective synthetic method.

    Effect of shock-thermal treatment on mechanical properties of steels (1989)
    Weinheim : Wiley-Blackwell
    Propellants, Explosives, Pyrotechnics 14 (1989), S. 238-240 
    Details
    ISSN: 0721-3115
    Keywords: Chemistry ; Polymer and Materials Science

    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: The shock-treatment permit to achieve high mechanical characteristics of steels. The interpretation of this effect is based on the possibility to change the carbon solubility in iron under these conditions. Measurements of the quality factors (internal friction in power-1) confirm this assumption.
