Experimental Study of Compressibility of a VNM-3-2 Alloy under Megabar Pressures

This paper describes an experimental study of isentropic compression of a VNM-3-2 heavy tungsten alloy (tungsten–nickel–copper) by a pressure of a superstrong pulsed magnetic field, induced by MC-1 magnetocumulative generator. Experimental points obtained on a p–ρ diagram of the alloy are compared with its cold compression curve, previously constructed on the basis of shock-wave experiments. The purpose of this study is to correct and clarify a equation of state of the alloy under an ultrahigh pressure and low temperature. This equation is used to analyze data obtained in experiments on isentropic compression of various substances.
