Thermophysical properties of multicomponent nickel-chromium alloy VSDP-3 upon melting and in the liquid phase

The study of the high-temperature properties of a complex composition $(\rm Ni$–$\rm Cr$–$\rm Al$–$\rm Re$–$\rm Hf$–$\rm Y)$ alloy was performed under the rapid heating of the foil by a single pulse current during a few microseconds. The alloy melted in the temperature range of $1670$ to $2050$ K and heated in a liquid state up to $4000$ K. There were measured thermal properties (energy Joule heating, electrical resistance, and specific heat) of the alloy in the area of melting and in the liquid phase. Temperature was determined by a pyrometry system based on Thorlabs’ highspeed photodetector PDA-10A (with prior calibration of the optical path using a temperature lamp).
