The results of a dilatometric study of the thermal coefficient of linear expansion of polycrystalline iron in the temperature range of 130–1180°K are presented. The measurements were made with an error of 3%. Temperature dependences were obtained and reference tables of the recommended values of volume properties were calculated. The region of the magnetic phase transition was studied in detail, and the critical indices of thermal expansion at the Curie point were determined.
