Thermal expansion of zirconium in the solid phase
Vyacheslav Petukhov

Thermal expansion of zirconium was investigated in the temperature ranges 350 – 1220 K and from 1035 – 1830 K in two dilatometers. The reasons for the change in the size of the sample in the phase transformation region are analysed. The obtained results are coprocessed with the available reference data. The recommended values of the thermal expansion of zirconium are given for temperatures from 350 to 1830 K.
