Popis:	We have found evidence of the existence of second- and third-order internal stresses within Fe powder grains (affected zone size: second order ≈ crystalline grains size; third order ≈ few interatomic distances) by means of X-ray diffraction. It is shown that the second-order internal stresses in powder grains induced during pulverization have qualitatively the same dependence on grain size and heat treatment as B H C .
