The method of experimental determination of adiabatic compression of nanopowders in soft pulsed compression is developed. The method is based on the measurement of the current values of the pressing pressure and the density of the compressible powder during pressing. This data set parametrically the adiabatic line of soft pulse compression and allow calculating the specific work of external forces to compress the powder. It is an operational tool for assessing the dynamic compressibility of powders and allows engineering calculations to predict the modes of pressing powders in forms with different sizes in the pressure range up to 1.5 GPa.

A numerical computer model describing satisfactorily the process of compression of powder media during compression of cylindrical billets by magnetic pulse compression of metal shells is created. The model is based on the actual characteristics of the shell material and the adiabatic compression of the pressed powder, which allows predicting the practically important characteristics of the pressing mode: the conditions of the shock wave in the compressed medium, the pressing pressure and the density of the resulting blanks, energy consumption.
