Popis:	The thermal expansion and magnetostriction of Nd2Fe14Si3 polycrystalline intermetallic compound was measured, using the strain gauge method in the temperature range 77–590 K under applied magnetic fields up to 1.5 T. Results show that both linear thermal expansion and linear thermal expansion coefficient exhibit anomalies below Curie temperature. A pronounced positive spontaneous volume magnetostriction has been observed below the Curie temperature. The spontaneous volume magnetostriction decreases with Si substitution in Nd2Fe17 compound. The saturation trend of the anisotropic magnetostriction below 115 K depends on the saturation of the λγ mode. In the low field region (μ0H
