Abstract: Since the 1960s, resistive pulse self-heating techniques, associated with 104 - 1010 K.s-1 heating rates, have been widely developed in order to study both solid and liquid states of pure and alloyed metals at very high temperature (up to 10,000 K). This paper is a review of the main recent results and advances obtained with such techniques. Thermophysical properties such as electrical resistivity, heat of fusion, melting points, volume expansion (density), heat capacity, thermal conductivity, thermal diffusivity, heat capacity, etc., of solid and liquid metals are then reachable throughout these high-speed experiments. This large set of thermophysical data may be completed with critical points determination as well as elastic constants data and equation-of-state parameters.
