During fast pulse-heating experiments an electrically conducting sample is heated rapidly by the passage of a large current pulse. Heating continues until the material evaporates (thus leading to the so-called 'wire-explosion'). Simultaneous measurements of temperature, voltage drop, current, and thermal expansion deliver thermophysical properties for the solid and liquid state. Within this study, thermal expansions of Ir, Pd, Pt, and V together with the respective resistivity polynomials are presented since resistivity includes the geometry of the sample. We have added available literature values to the graphs. The notable agreement of the platinum curves was taken as a starting point for conclusions. The results are part of a compilation (the 'pulse-heating data collection') of 22 pure elements measured under the same experimental conditions (pulse-heating at TU Graz).
